For example, Suresh Kumar born in 1990 would use SURE1990. If you need a copy without a password for an upload, open it with the password and save an unlocked copy using Remove PDF password. - [Excel to PDF: How to Fit All Columns on One Page](https://indiadigital.org/blog/excel-to-pdf-fit-one-page/): To fit Excel columns on one PDF page, remove empty or unneeded columns, narrow the remaining ones, and use landscape orientation for wide sheets. IndiaDigital's Excel to PDF tool does much of this automatically: it draws every sheet as a gridded table, switches wide sheets to landscape and shrinks them to fit the page width. Always check that the text is still large enough to read. - [How to Compress a PDF to 100 KB, 200 KB, 500 KB or 1 MB (Free, No Upload)](https://indiadigital.org/blog/compress-pdf-to-100kb/): Open Target-size PDF, add your file, type the limit the portal asks for (for example 100 KB or 200 KB) and download the result. It first tries shrinking the pictures inside the PDF so your text stays sharp and selectable, and only turns pages into images if that is the only way to hit the limit. Everything happens in your browser, so the document is never uploaded. - [How to Compress a Pitch Deck (PPTX) for Email and Investor Portals](https://indiadigital.org/blog/compress-pitch-deck-pptx/): Most oversized pitch decks are heavy because of full-resolution photos, screenshots and embedded video, not text. Run the deck through Compress PowerPoint on the Recommended level to downsample and re-encode the pictures while keeping slides, animations and notes exactly as they are. If the portal still rejects it, export a PDF and compress that, or move the video to a link. - [How to Compress Images Without Losing Visible Quality](https://indiadigital.org/blog/compress-image-without-losing-quality/): Resize the image to the largest size it will actually be shown at, choose the right format (JPEG or WebP for photos, PNG for screenshots and logos), and use a moderate quality setting rather than the maximum. Removing metadata saves a little more. The Batch image compressor does this for many images at once in your browser. - [How to Convert iPhone HEIC Photos to JPG on Windows, Android and for Portals](https://indiadigital.org/blog/heic-to-jpg-windows/): Open the HEIC converter in any modern browser on Windows or Android, add your iPhone HEIC photos and download them as JPG or PNG; you can convert many at once and nothing is uploaded. To stop getting HEIC files in future, set your iPhone camera to Most Compatible in Settings, under Camera and then Formats. - [How to Convert PDF to Editable Word (Text and Scanned PDFs)](https://indiadigital.org/blog/pdf-to-word-editable/): If your PDF contains real text (you can select words in it), a PDF to Word converter can rebuild its paragraphs, headings, tables and pictures into an editable .docx. If it is a scanned PDF, the pages are just pictures, so run OCR first to add a text layer and then convert. Expect to spend a few minutes tidying spacing and columns afterwards. - [How to Convert Word to PDF Without Losing Formatting](https://indiadigital.org/blog/word-to-pdf-keep-formatting/): To convert Word to PDF without losing formatting, save the file as .docx, use common or embedded fonts, set the right page size (A4 for most Indian and international use) and convert with a tool that renders headings, tables and pictures faithfully. Then open the PDF and check every page before you send it, because fonts that are not installed on the converting device are the most common reason layouts shift. - [How to Edit a PDF Free: Add Text, White-out, Highlight and Sign](https://indiadigital.org/blog/edit-pdf-free/): Use Edit PDF to add new text, white-out areas, highlight, draw and place pictures on any page, all in your browser with no upload. It does not change existing text in place, and white-out only hides content visually, so use Redact PDF to remove sensitive information permanently and PDF to Word when you need to rewrite large parts of a document. - [How to Make a Passport-Size Photo at Home for Online Applications](https://indiadigital.org/blog/passport-size-photo-online/): Take a well-lit, front-facing photo against a plain light wall, then crop it to the exact pixel size your form asks for. To convert centimetres to pixels, use pixels = cm ÷ 2.54 × DPI; for example 3.5 cm × 4.5 cm at 300 DPI is about 413 × 531 pixels. Always follow your own notification or official portal for the actual specification. - [How to Merge PDF Files Free, in the Right Order, Without Uploading](https://indiadigital.org/blog/merge-pdf-files-free/): Open Merge PDF, add all your PDF files, drag them into the order you want and download one combined file. It runs entirely in your browser, so nothing is uploaded and there is no watermark. If you then need to move, delete or rotate individual pages, use Organize PDF, and run Compress PDF if the merged file is too large. - [How to Password-Protect a PDF (and What Protection Really Does)](https://indiadigital.org/blog/password-protect-pdf/): To password-protect a PDF, open Encrypt PDF, add your file, set a password of at least 12 characters and download the AES-256 encrypted copy. Anyone opening it will need that password. Send the password through a different channel from the file, and remember that once someone opens the document they can still share what they see. - [How to Reduce Excel File Size: Pictures, Ranges, Pivot Caches and More](https://indiadigital.org/blog/reduce-excel-file-size/): If your workbook contains pictures, logos or pasted screenshots, Compress Excel (XLSX) can shrink them in your browser without touching a single formula or value. If the file is mostly data, the bloat usually comes from oversized used ranges, saved pivot caches or excess formatting, which you fix inside Excel. Saving as .xlsb is another option for very large data workbooks. - [How to Reduce Photo Size to 20 KB, 50 KB or 100 KB for Online Forms](https://indiadigital.org/blog/reduce-photo-size-20kb-50kb/): To reduce a photo to 20 KB, 50 KB or 100 KB, first crop and resize it to the pixel size your form asks for, then save it as JPEG at whatever quality lands just under the KB limit. IndiaDigital's Photo and signature size optimizer does both steps in your browser: you set the maximum width, height and target KB, and it searches for the best quality that fits. - [How to Reduce Word Document File Size (DOCX) Without Losing Formatting](https://indiadigital.org/blog/reduce-word-file-size/): Word files are usually large because of uncompressed pictures, embedded fonts or a long history of tracked changes. Use Compress Word (DOCX) to downsample and re-encode the images while leaving your text and formatting untouched, then fix fonts and tracked changes in Word if the file is still heavy. The whole process runs in your browser, so the document never leaves your device. - [How to Resize Your Signature for Online Application Forms](https://indiadigital.org/blog/signature-size-online-form/): Sign with a dark pen on plain white paper, photograph it in good light, crop tightly around the signature and save it as a JPEG under the KB limit in your notification. The Photo and signature size optimizer lets you crop, set the pixel size and target KB in one go, entirely in your browser. - [How to Sign a PDF Online Free (and When You Need a DSC Instead)](https://indiadigital.org/blog/sign-pdf-online-free/): Open Sign PDF, add your file, then type, draw or upload an image of your signature and place it on the page. This creates a visual electronic signature, which is accepted for many everyday documents such as offer letters, NDAs and internal approvals. It is not a certificate-based digital signature (DSC), so for filings and processes that require a DSC or Aadhaar eSign, use those instead and always check the receiving organisation's rules. - [How to Split a PDF and Extract Pages: Single Pages, Ranges and More](https://indiadigital.org/blog/split-pdf-pages/): To split a PDF, open Split PDF, add the file and choose whether to extract specific pages, save each page as its own PDF, or cut the document into ranges such as 1-5 and 6-12. If you are splitting to get under an email or upload limit, split by size instead. Everything runs in your browser, so the original file is never uploaded. - [Is It Safe to Upload PDFs to Online Tools? How to Protect Your Documents](https://indiadigital.org/blog/is-it-safe-to-upload-pdf-online/): Uploading a PDF to an online tool means sending a copy to someone else's server, where it may be stored, logged or accessed in ways you cannot see. For sensitive documents such as Aadhaar, PAN, bank statements or payslips, prefer tools that process files inside your browser, and verify it yourself by watching the Network tab in your browser's developer tools while the tool runs. Redact what the recipient does not need and password-protect files before sharing. - [JPG to PDF: Combine Photos and Scans Into One PDF](https://indiadigital.org/blog/jpg-to-pdf/): To turn photos into one PDF, open IndiaDigital's Images to PDF tool, add your JPG or PNG files, drag them into the right order and download a single PDF. iPhone photos in HEIC format need converting to JPG first with the HEIC converter. Crop and straighten photos before converting, and compress the PDF if a portal has a size limit. - [PDF to JPG: Turn PDF Pages Into Images for WhatsApp and Slides](https://indiadigital.org/blog/pdf-to-jpg/): To convert a PDF to JPG, open IndiaDigital's PDF to JPG and PNG tool, add the PDF and download every page as an image. Choose JPG for photo-heavy pages and small files, PNG for sharp text, diagrams and screenshots, and a higher resolution if people will zoom in or print. To get the original photos inside a PDF rather than whole pages, use Extract embedded images. - [PDF Too Large to Email? 3 Free Ways to Send It](https://indiadigital.org/blog/pdf-too-large-for-email/): Most free email services, including Gmail and Outlook.com, accept attachments of around 20 to 25 MB in total per message, and the exact figure varies by provider and account. If your PDF is larger, compress it with Compress PDF, split it into parts that each fit with Split PDF by size, or upload it to cloud storage and send a link instead. - [PowerPoint to PDF: Share Decks and Handouts That Look Right](https://indiadigital.org/blog/powerpoint-to-pdf-slides/): Convert PowerPoint to PDF whenever you are sending a deck for someone to read rather than present, because a PDF opens on any phone or laptop and looks the same everywhere. IndiaDigital draws each slide with its theme colours, backgrounds, text, bullets, pictures, shapes and tables, but animations, video, charts and SmartArt are not drawn, so replace those with static pictures first. - [Should You Send Your Pitch Deck as PDF or PPTX?](https://indiadigital.org/blog/pitch-deck-pdf-or-pptx/): For a first, unsolicited send, a PDF is usually the safer choice: it looks exactly as designed on any device, is hard to edit by accident and tends to be smaller. Send PPTX only when someone asks for an editable file or needs to present it live. Whatever the format, follow the investor's or programme's instructions first and run through a short pre-send checklist. ## Everyday help for India (official-service routes) - [Education & students](https://indiadigital.org/help/education/) - [Jobs & skills](https://indiadigital.org/help/careers/) - [Identity & certificates](https://indiadigital.org/help/identity/) - [Money & records](https://indiadigital.org/help/money/) - [Health services](https://indiadigital.org/help/health/) - [Business & founders](https://indiadigital.org/help/business/) - [Travel & deliveries](https://indiadigital.org/help/travel/) - [Consumer rights & safety](https://indiadigital.org/help/consumer/) ## About - [About](https://indiadigital.org/about/) - [Privacy](https://indiadigital.org/privacy/) - [Methodology](https://indiadigital.org/methodology/) - [Compatibility](https://indiadigital.org/compatibility/) ## Guide details ### e-Aadhaar PDF Password: How to Open It and Save an Unlocked Copy URL: https://indiadigital.org/blog/aadhaar-pdf-password/ Per UIDAI's documented format, the e-Aadhaar PDF password is the first four letters of your name as printed on Aadhaar, in CAPITAL letters, followed by your year of birth in YYYY format. For example, Suresh Kumar born in 1990 would use SURE1990. If you need a copy without a password for an upload, open it with the password and save an unlocked copy using Remove PDF password. 1. Download your e-Aadhaar PDF from the official UIDAI website or app to your own device. 2. Work out the password: the first four letters of your name as on Aadhaar in capital letters, followed by your four-digit year of birth. 3. Open the PDF in any PDF reader and type the password to confirm it works. 4. If a portal needs a file without a password, open Remove PDF password on IndiaDigital and select your e-Aadhaar PDF. 5. Enter the same password; the tool creates an unlocked copy in your browser without uploading the file. 6. Download the unlocked copy, upload it where required, and delete any copies you no longer need. Q: What is the password for the e-Aadhaar PDF? A: Per UIDAI's documented format, it is the first four letters of your name as on Aadhaar in capital letters, followed by your year of birth in YYYY format. For example, Suresh Kumar born in 1990 would use SURE1990. Q: What if my name has fewer than four letters? A: UIDAI provides guidance for names shorter than four letters. Please check UIDAI's official instructions for how the password is formed in that case rather than trying random combinations. Q: Can I remove the password from my Aadhaar PDF? A: Yes, if you know the password. Open the file with Remove PDF password on IndiaDigital and it will save an unlocked copy in your browser. It cannot recover or bypass a password you do not know. Q: Is it safe to unlock my Aadhaar PDF online? A: IndiaDigital processes the file inside your browser, so your Aadhaar PDF is not uploaded to our servers. Even so, the unlocked copy is unprotected, so use it only where needed and delete it afterwards. Q: Is IndiaDigital connected to UIDAI? A: No. IndiaDigital is an independent website offering free file tools. For downloading e-Aadhaar, updating your details or any official query, use UIDAI's official website, app or help channels. ### Excel to PDF: How to Fit All Columns on One Page URL: https://indiadigital.org/blog/excel-to-pdf-fit-one-page/ To fit Excel columns on one PDF page, remove empty or unneeded columns, narrow the remaining ones, and use landscape orientation for wide sheets. IndiaDigital's Excel to PDF tool does much of this automatically: it draws every sheet as a gridded table, switches wide sheets to landscape and shrinks them to fit the page width. Always check that the text is still large enough to read. 1. Open the workbook and delete or move any columns and sheets the reader does not need. 2. Narrow wide columns, wrap long text and shorten column headers where possible. 3. Unhide or delete hidden rows and columns so you know exactly what will appear. 4. Save the file as .xlsx and open the Excel to PDF tool on IndiaDigital. 5. Drop in the workbook; wide sheets are switched to landscape and scaled to fit the page width automatically. 6. Open the PDF, zoom to normal size and confirm that numbers are readable and no column is missing. Q: Why are some of my Excel columns missing from the PDF? A: Columns that do not fit the page width are often pushed to separate pages, or they may be hidden in the workbook. IndiaDigital shrinks wide sheets to fit the page width, so check whether the columns are hidden in Excel and unhide them before converting. Q: Does the PDF include charts from my workbook? A: No, charts and embedded pictures are not drawn by the Excel to PDF tool at the moment. Copy the chart into a Word document or export it as an image, convert that separately, and then merge the PDFs. Q: Can I convert only one sheet of a workbook? A: The tool converts every sheet. To get a single sheet, save a copy of the workbook, delete the other sheets from the copy and convert that. Q: The text in my PDF is too small to read. What can I do? A: The sheet has too many columns for one page width. Remove unneeded columns, narrow the rest and shorten headers, or split the data into two sheets so each one fits at a readable size. Q: Are formulas kept in the PDF? A: A PDF shows the calculated results, formatted as they appear in Excel, not the formulas themselves. That is often the point: the reader sees the numbers but cannot change them by accident. ### How to Compress a PDF to 100 KB, 200 KB, 500 KB or 1 MB (Free, No Upload) URL: https://indiadigital.org/blog/compress-pdf-to-100kb/ Open Target-size PDF, add your file, type the limit the portal asks for (for example 100 KB or 200 KB) and download the result. It first tries shrinking the pictures inside the PDF so your text stays sharp and selectable, and only turns pages into images if that is the only way to hit the limit. Everything happens in your browser, so the document is never uploaded. 1. Open the Target-size PDF tool at indiadigital.org/pdf/target-size-pdf/ in any modern browser. 2. Drag your PDF onto the page or tap to choose it from your phone or computer. 3. Enter the size the portal allows, such as 100 KB, 200 KB, 500 KB or 1 MB. Aim slightly below the limit, for example 95 KB for a 100 KB cap. 4. Start the compression and wait while the tool tries gentle picture compression first, then stronger steps only if needed. 5. Download the new file and check the size shown in your file manager or the download bar. 6. Open the downloaded PDF and zoom in on names, numbers and signatures to make sure everything is still readable before you upload it to the portal. Q: Can I compress a PDF to 100 KB without losing quality? A: Only if most of the size comes from things that can be removed or packed more efficiently, such as oversized images in a typed document. A multi-page colour scan will always lose some detail when squeezed to 100 KB. The aim is to keep it clearly readable, which is what portals actually need. Q: Why does the compressed PDF look blurry? A: The tool had to reduce picture resolution heavily or rasterise pages to reach a very small target. Try a slightly higher target if the portal allows it, remove unnecessary pages, or rescan in greyscale so less detail has to be thrown away. Q: Is it safe to compress my Aadhaar or mark sheet online? A: With IndiaDigital the file is processed inside your browser and is not uploaded to any server. You can confirm this yourself by watching the Network tab in your browser's developer tools while it runs. Our article on whether it is safe to upload PDFs online explains how. Q: Does this work on a phone? A: Yes. The tools work in mobile browsers such as Chrome and Safari. Very large files may be slower on older phones because all the work happens on the device, so close other apps if it feels sluggish. Q: The portal says my file is too large even though it shows 99 KB. Why? A: Some systems measure a kilobyte as 1,000 bytes and others as 1,024 bytes, and a few also count form data sent with the file. Target a little below the stated limit, for example 90 to 95 KB for a 100 KB cap, to stay safe. ### How to Compress a Pitch Deck (PPTX) for Email and Investor Portals URL: https://indiadigital.org/blog/compress-pitch-deck-pptx/ Most oversized pitch decks are heavy because of full-resolution photos, screenshots and embedded video, not text. Run the deck through Compress PowerPoint on the Recommended level to downsample and re-encode the pictures while keeping slides, animations and notes exactly as they are. If the portal still rejects it, export a PDF and compress that, or move the video to a link. 1. Save a copy of your deck as .pptx (re-save older .ppt files in PowerPoint first). 2. Open Compress PowerPoint on IndiaDigital and drop the file in; nothing is uploaded. 3. Choose the Recommended level, or Strong if you need the smallest possible file. 4. Start compression and download the new file once it finishes. 5. Open the compressed deck and check your photo-heavy slides, charts and logos at full screen. 6. Compare the new size with the portal or email limit; if it is still too big, remove or link out embedded video, or send a PDF version. Q: Will compressing my deck ruin the image quality? A: On the Recommended level, pictures are downsampled to a resolution that still looks sharp on laptop and projector screens, so most people will not notice a difference. If your deck relies on detailed photography, try Light first. Always keep your original file in case you need full quality later. Q: Does the tool remove my animations or speaker notes? A: No. Only pictures and unreferenced media are changed. Slide text, layouts, animations, transitions, charts and speaker notes stay exactly as they were. Q: Why did my file barely shrink? A: The weight is probably in an embedded video, which the tool keeps as it is. Check the media folder or remove the video from a test copy to confirm, then replace it with a link or send a PDF version. Q: Can I compress an old .ppt file? A: Not directly. Open it in PowerPoint and use Save As to save it in the modern .pptx format, then compress the new file. Q: Is my pitch deck uploaded anywhere? A: No. The compression runs entirely in your browser, so the file stays on your device. There is no sign-up and no watermark on the output. ### How to Compress Images Without Losing Visible Quality URL: https://indiadigital.org/blog/compress-image-without-losing-quality/ Resize the image to the largest size it will actually be shown at, choose the right format (JPEG or WebP for photos, PNG for screenshots and logos), and use a moderate quality setting rather than the maximum. Removing metadata saves a little more. The Batch image compressor does this for many images at once in your browser. 1. Decide where the image will be used and the largest width it will be displayed at. 2. Resize the image down to that width with the Resize and crop tool. 3. Choose the format: JPEG or WebP for photos, PNG for screenshots, logos and flat graphics. 4. Open the Batch image compressor, pick the format and start with a moderate quality setting. 5. Compare the result with the original at 100% zoom and adjust quality up or down. 6. Strip metadata if the image will be shared publicly, then save the final copies. Q: Can I really compress an image without losing quality? A: With lossless formats such as PNG, yes, every pixel stays identical, though savings for photos are limited. With lossy formats such as JPEG and WebP, some data is discarded, but with sensible resizing and quality settings the difference is usually not visible at normal viewing size. Q: Is WebP better than JPEG? A: For websites, WebP often produces smaller files at similar visual quality and supports transparency. JPEG is more universally accepted, so for application forms, email attachments and older software, JPEG is usually the safer choice. Q: Why is my PNG photo so large? A: PNG is lossless and designed for flat graphics, so it stores every detail of a photograph, including noise. Convert photos to JPEG or WebP for much smaller files, and keep PNG for screenshots, logos and diagrams. Q: What quality setting should I use for JPEG? A: There is no single correct number because it depends on the image. Start at a moderate to high setting, compare with the original at full zoom, and lower it until you just start to notice a difference, then step back up slightly. Q: Should I resize or compress first? A: Resize first. Reducing the pixel dimensions to what you actually need usually gives the biggest saving, and then a lighter compression setting is enough to reach your target size with better visual quality. ### How to Convert iPhone HEIC Photos to JPG on Windows, Android and for Portals URL: https://indiadigital.org/blog/heic-to-jpg-windows/ Open the HEIC converter in any modern browser on Windows or Android, add your iPhone HEIC photos and download them as JPG or PNG; you can convert many at once and nothing is uploaded. To stop getting HEIC files in future, set your iPhone camera to Most Compatible in Settings, under Camera and then Formats. 1. Copy the HEIC photos from your iPhone to your Windows PC or Android phone (by cable, cloud storage or file sharing). 2. Open the HEIC converter on IndiaDigital in your browser. 3. Select or drag in one or more .heic files. 4. Choose JPG as the output format (or PNG if you need lossless output). 5. Convert and download the files; with several photos, download them together. 6. If the JPG is for an online form, resize and compress it to the required size before uploading. Q: How do I convert HEIC to JPG on Windows for free? A: Open the HEIC converter on IndiaDigital in your browser, add your .heic files, choose JPG and download. It is free, needs no sign-up or installation, and processes the photos on your own PC without uploading them. Q: Does converting HEIC to JPG reduce quality? A: JPG uses lossy compression, so there is some theoretical loss, but at a good quality setting the difference is usually not visible. If you need a lossless copy for editing, choose PNG, which will give a much larger file. Q: Can I convert HEIC to JPG on an Android phone? A: Yes. Open the HEIC converter in your phone's browser, select the HEIC files and download the JPGs. The conversion runs on the phone itself, so it works the same as on a computer. Q: Why does my exam portal reject my iPhone photo? A: Usually because it is HEIC rather than JPG, or because it is far larger than the KB limit. Convert it to JPG first, then resize and compress it to the dimensions and KB range in your notification. Q: Will changing my iPhone to Most Compatible convert old photos? A: No. The setting only affects photos taken after you change it. Photos already saved as HEIC stay that way and need to be converted separately. ### How to Convert PDF to Editable Word (Text and Scanned PDFs) URL: https://indiadigital.org/blog/pdf-to-word-editable/ If your PDF contains real text (you can select words in it), a PDF to Word converter can rebuild its paragraphs, headings, tables and pictures into an editable .docx. If it is a scanned PDF, the pages are just pictures, so run OCR first to add a text layer and then convert. Expect to spend a few minutes tidying spacing and columns afterwards. 1. Open the PDF and try to select a line of text to find out whether it is a text PDF or a scanned one. 2. If the text cannot be selected, run the file through Searchable OCR first to add a text layer. 3. Open the PDF to Word tool on IndiaDigital and drop in the PDF. It is processed in your browser, not uploaded. 4. Download the .docx and open it in Word, Google Docs or LibreOffice. 5. Tidy up: fix any merged columns, check tables and replace fonts if needed. 6. Save your edited document, and convert it back with Word to PDF if you need to send a PDF. Q: Why is my converted Word file just pictures of the pages? A: Your PDF is a scan, so the pages contain pictures rather than text. Run it through Searchable OCR first to add a text layer, then convert it to Word again. Proofread the result, because OCR can misread some characters. Q: Why did a two-column PDF turn into a single column? A: Multi-column layouts and text boxes are rebuilt as a single flow of text so that it reads in order and stays editable. If you need columns back, select the section in Word and apply the Columns setting. Q: Will tables come across as real Word tables? A: Tables built from clearly aligned columns are rebuilt as editable tables. Tables with merged cells, rotated text or no visible alignment may need some tidying. For data-heavy tables, PDF to Excel is often the better choice. Q: Can I convert a password-protected PDF? A: If the PDF needs a password to open, you will need to open it with that password in a viewer first. Only convert documents you own or are permitted to edit. Q: Does the PDF get uploaded anywhere? A: No. On IndiaDigital the conversion runs in your browser, so your file stays on your device. There is no account or watermark involved. ### How to Convert Word to PDF Without Losing Formatting URL: https://indiadigital.org/blog/word-to-pdf-keep-formatting/ To convert Word to PDF without losing formatting, save the file as .docx, use common or embedded fonts, set the right page size (A4 for most Indian and international use) and convert with a tool that renders headings, tables and pictures faithfully. Then open the PDF and check every page before you send it, because fonts that are not installed on the converting device are the most common reason layouts shift. 1. Open the document in Word and save it as .docx (File, Save As, Word Document) if it is still an old .doc file. 2. Check the page size and margins under Layout, and pick A4 unless the recipient has asked for Letter. 3. Swap any unusual fonts for widely available ones such as Calibri, Arial, Cambria or Times New Roman, or note which fonts may be approximated. 4. Open the Word to PDF tool on IndiaDigital and drop in your .docx file. It is processed in your browser and never uploaded. 5. Download the PDF and scroll through every page, comparing line breaks, tables and pictures with the original. 6. If the file is too large for a job portal or email, run it through Compress PDF and check it again. Q: Why did my fonts change when I converted Word to PDF? A: The converting device did not have the font your document asked for, so it used the closest available match. Switching to a widely installed font such as Calibri, Arial or Times New Roman usually solves it. If you must keep a special font, convert on a computer where that font is installed. Q: Can I convert an old .doc file to PDF? A: Not directly with the browser tool. Open the .doc file in Word, LibreOffice or Google Docs, save it as .docx, and then convert. Re-saving is quick and also makes the file easier to work with in the future. Q: Will my CV still be readable by applicant tracking systems? A: Yes, the text in the PDF stays selectable, so software that reads the text layer can pick it up. Keep the layout simple, avoid putting important details only inside pictures, and test by selecting and copying some text from the PDF. Q: Why is there a blank page at the end of my PDF? A: Usually an empty paragraph or a page break sits after your last line of text. Turn on formatting marks in Word, delete anything after the final line, save and convert again. Q: Is it safe to convert confidential documents? A: On IndiaDigital the conversion happens in your browser, so the file is not uploaded to a server. As with any device, close the tab and delete downloaded copies if you are using a shared or public computer. ### How to Edit a PDF Free: Add Text, White-out, Highlight and Sign URL: https://indiadigital.org/blog/edit-pdf-free/ Use Edit PDF to add new text, white-out areas, highlight, draw and place pictures on any page, all in your browser with no upload. It does not change existing text in place, and white-out only hides content visually, so use Redact PDF to remove sensitive information permanently and PDF to Word when you need to rewrite large parts of a document. 1. Open Edit PDF and add your PDF file from your device. 2. Choose the Text tool, click where you want to type and enter your text. Adjust the size and colour to match the document. 3. Use White-out to cover a small mistake or an empty box, then add corrected text on top if needed. 4. Use Highlight or Draw to mark important lines, tick boxes or circle figures. 5. Add a picture, such as a stamp, logo or photo, and resize it on the page. 6. Save and download the edited PDF, then open it to check every change before sharing. Q: Can I edit the existing text in a PDF for free? A: Edit PDF adds new content on top of the page and does not reflow existing text. For small fixes, white-out the old text and type the new value over it. For larger rewrites, convert the file with PDF to Word, edit it, and save it as a PDF again. Q: Is white-out safe for hiding my Aadhaar or bank details? A: No. White-out only hides content visually, and the original information usually remains in the file. Use Redact PDF, which removes the content underneath permanently, and then search the file to confirm it is gone. Q: Will editing a PDF add a watermark? A: No. IndiaDigital does not add watermarks or branding to your files, and there is no sign-up or paid tier to unlock clean downloads. Q: Can I edit a scanned PDF? A: Yes, you can add text, highlights, drawings and images on top of a scanned page in the same way. You cannot change the scanned words themselves because they are part of a picture, so white-out and write over them if needed. Q: Does Edit PDF work on mobile? A: Yes, it works in modern mobile browsers. Placing small text precisely is easier on a larger screen, so for detailed forms a laptop or tablet may be more comfortable. ### How to Make a Passport-Size Photo at Home for Online Applications URL: https://indiadigital.org/blog/passport-size-photo-online/ Take a well-lit, front-facing photo against a plain light wall, then crop it to the exact pixel size your form asks for. To convert centimetres to pixels, use pixels = cm ÷ 2.54 × DPI; for example 3.5 cm × 4.5 cm at 300 DPI is about 413 × 531 pixels. Always follow your own notification or official portal for the actual specification. 1. Read the photo instructions in your notification or on the official portal: size, background colour, file format and KB range. 2. Stand about half a metre in front of a plain light wall, facing a window, with someone holding the phone at your eye level. 3. Take several photos looking straight at the camera with a neutral expression, eyes open and face fully visible. 4. Open the Application photos tool, choose the clearest photo and set the exact pixel width and height required. 5. Position the crop so your head and the top of your shoulders are centred with a small gap above the head, then export. 6. If the file is over the KB limit, run it through the Photo and signature size optimizer with the same dimensions and a target KB. Q: What is 3.5 cm × 4.5 cm in pixels? A: At 300 DPI it is about 413 × 531 pixels, using pixels = cm ÷ 2.54 × DPI. At a different DPI the pixel numbers change. If your form gives pixel dimensions directly, use those instead. Q: Can I take a passport-size photo with my phone? A: For many online applications, yes, as long as the photo meets the stated requirements for background, lighting, framing, size and format. Check your official instructions, as some services have specific rules or ask for studio-quality prints. Q: What background colour should I use? A: Follow your notification. Many forms ask for a white or light background, but some specify a particular shade. A plain light wall in daylight is usually the easiest way to get a clean result. Q: What are the official Indian passport photo requirements? A: Please follow the photo guidelines published on the official Passport Seva portal, since they are the authoritative source and can be updated. This guide explains the general method only and does not restate any official specification. Q: Is my photo uploaded when I crop it on IndiaDigital? A: No. The Application photos tool and the other image tools process your photo inside your browser. Nothing is sent to our servers, there is no sign-up and no watermark is added. ### How to Merge PDF Files Free, in the Right Order, Without Uploading URL: https://indiadigital.org/blog/merge-pdf-files-free/ Open Merge PDF, add all your PDF files, drag them into the order you want and download one combined file. It runs entirely in your browser, so nothing is uploaded and there is no watermark. If you then need to move, delete or rotate individual pages, use Organize PDF, and run Compress PDF if the merged file is too large. 1. Rename your files with numbers at the start (01, 02, 03) so they sort in the right order when you select them. 2. Open Merge PDF and add all the files at once, or add them one by one. 3. Drag the files into the order you want the final document to follow. 4. Merge and download the combined PDF. 5. Open it in Organize PDF if you need to delete blank pages, move single pages or rotate sideways scans. 6. Compress the final file if it is too large for email or an upload portal, then check every page before sending. Q: Is there a limit on how many PDFs I can merge? A: There is no fixed file count, but because merging happens on your device, the practical limit depends on its memory. Dozens of normal documents are usually fine. For very large scans on an older phone, merge in smaller batches and then merge the batches. Q: Will the merged PDF have a watermark? A: No. IndiaDigital does not add watermarks, logos or extra pages to your files. The merged document contains only your pages. Q: Can I merge PDFs on my phone? A: Yes. Merge PDF works in mobile browsers on Android and iPhone. You can pick files from your downloads, file manager or cloud storage app, reorder them on screen and save the merged file back to your phone. Q: Does merging reduce the quality of my documents? A: No. Merging copies pages as they are, so text and images keep their original quality. Quality only changes if you compress the file afterwards. Q: Can I merge Word files or images with PDFs? A: Convert them to PDF first. Use Images to PDF for photos and scans, and export Word documents to PDF from your word processor, then merge all the PDFs together. ### How to Password-Protect a PDF (and What Protection Really Does) URL: https://indiadigital.org/blog/password-protect-pdf/ To password-protect a PDF, open Encrypt PDF, add your file, set a password of at least 12 characters and download the AES-256 encrypted copy. Anyone opening it will need that password. Send the password through a different channel from the file, and remember that once someone opens the document they can still share what they see. 1. Create a long passphrase, or generate one with the Password generator, and store it in your password manager. 2. Open Encrypt PDF on IndiaDigital and add your PDF; the file stays on your device. 3. Enter the password (12 characters or more) and confirm it. 4. Run the encryption and download the protected PDF. 5. Test it by opening the new file and entering the password. 6. Send the PDF by email or link, and share the password separately, for example by phone or a different messaging app. Q: Can a password-protected PDF be cracked? A: With AES-256 and a long, random password, guessing is not practical with current technology. Short or predictable passwords are the real weakness, which is why a 12-character minimum and a generated passphrase matter. Q: Will the recipient need special software? A: No. Modern PDF readers, including Adobe Acrobat Reader, Chrome, Edge, and the built-in viewers on iPhone, Android and macOS, open AES-256 PDFs after asking for the password. Very old readers may not support it. Q: I forgot the password. Can you unlock the file? A: No. The encryption is designed so that nobody can open the file without the password, including us. This is why you should save the password in a password manager and keep an unencrypted original somewhere safe. Q: Does protecting a PDF make it larger? A: Usually only slightly. If you need a small file as well, compress it with Compress PDF first and then encrypt the result, because an encrypted file cannot be processed without the password. Q: Is an owner password enough to stop copying? A: Not reliably. Permission restrictions depend on the reading app respecting them, and many do not. A visible watermark naming the recipient is often a stronger deterrent. ### How to Reduce Excel File Size: Pictures, Ranges, Pivot Caches and More URL: https://indiadigital.org/blog/reduce-excel-file-size/ If your workbook contains pictures, logos or pasted screenshots, Compress Excel (XLSX) can shrink them in your browser without touching a single formula or value. If the file is mostly data, the bloat usually comes from oversized used ranges, saved pivot caches or excess formatting, which you fix inside Excel. Saving as .xlsb is another option for very large data workbooks. 1. Keep a backup copy of the original workbook. 2. If the workbook has pictures, run it through Compress Excel (XLSX) on the Recommended level. 3. Open the result and confirm images, charts and formulas look and calculate correctly. 4. In Excel, delete unused rows and columns beyond your real data on each sheet and save to reset the used range. 5. Turn off 'Save source data with file' on pivot tables you refresh anyway, and clear unused cell styles and conditional formats. 6. Save, close and reopen to see the new size; consider .xlsb only if everyone who needs the file uses desktop Excel. Q: Will compressing an Excel file change my formulas or data? A: No. The compressor only changes embedded pictures and unused media, then repacks the file. Cell values, formulas, charts, pivots and named ranges are left as they are. Q: Why did my workbook barely shrink? A: It probably has little media and most of its size comes from data, used ranges, pivot caches or formatting. Those need to be cleaned up inside Excel, as described in this guide. Q: What is a pivot cache and why is it big? A: It is a saved copy of the source data that a pivot table summarises. Keeping it in the file lets the pivot work without the source, but it can roughly duplicate a large dataset. You can choose not to save it if you always refresh from the source. Q: Should I switch to .xlsb? A: It can make big data workbooks smaller and faster in desktop Excel. Avoid it for files you share widely, because not every app can open binary workbooks and some organisations block them. Q: Can I compress .xls or .xlsm files? A: Legacy .xls files need to be re-saved as .xlsx first. Macro-enabled workbooks are a separate format, so save a macro-free .xlsx copy if you want to compress it in the browser. ### How to Reduce Photo Size to 20 KB, 50 KB or 100 KB for Online Forms URL: https://indiadigital.org/blog/reduce-photo-size-20kb-50kb/ To reduce a photo to 20 KB, 50 KB or 100 KB, first crop and resize it to the pixel size your form asks for, then save it as JPEG at whatever quality lands just under the KB limit. IndiaDigital's Photo and signature size optimizer does both steps in your browser: you set the maximum width, height and target KB, and it searches for the best quality that fits. 1. Read your notification or the portal instructions and note the required file format, pixel dimensions (if given) and minimum and maximum size in KB. 2. Open the Photo and signature size optimizer and select your photo. Nothing is uploaded; the file stays on your device. 3. Drag the crop box so your face and shoulders fill the frame in the proportion the form expects. 4. Enter the maximum width and height in pixels, choose JPEG, and type the target size in KB (for example 45 if the limit is 50 KB). 5. Run the optimizer, check the preview at 100% zoom for blur or blocky patches, and download the result. 6. Check the downloaded file size in your file manager before uploading, and keep the original photo safe in case you need to redo it. Q: How do I reduce a photo to exactly 20 KB? A: You rarely need exactly 20 KB; you need 20 KB or less, and sometimes above a stated minimum. Crop and resize the photo to the required pixels, then set a target of around 18 to 19 KB in the Photo and signature size optimizer so it lands safely under the limit. Q: Does changing DPI reduce the file size in KB? A: No. DPI is a label telling a printer how densely to place pixels. Changing it without changing the pixel dimensions leaves the file size almost unchanged. To reduce KB, reduce the pixels or the JPEG quality. Q: Will reducing the photo size make it blurry? A: Some detail is always lost, but at typical form sizes a well-lit photo stays clear. Resizing to the needed pixels first and compressing second gives a much better result than forcing a huge photo down with very low quality. Q: Is it safe to compress my photo online? A: IndiaDigital's image tools run in your browser, so your photo is processed on your own device and not uploaded to a server. You can read more in our article on whether it is safe to upload files online. Q: What size should my photo be for my exam form? A: That depends entirely on your exam. Each notification states its own dimensions, KB range, background and format, and they differ between exams and years. Check the official notification or portal instructions and use those exact values. ### How to Reduce Word Document File Size (DOCX) Without Losing Formatting URL: https://indiadigital.org/blog/reduce-word-file-size/ Word files are usually large because of uncompressed pictures, embedded fonts or a long history of tracked changes. Use Compress Word (DOCX) to downsample and re-encode the images while leaving your text and formatting untouched, then fix fonts and tracked changes in Word if the file is still heavy. The whole process runs in your browser, so the document never leaves your device. 1. Make sure the file is in .docx format; re-save any older .doc file in Word first. 2. Open Compress Word (DOCX) on IndiaDigital and add one or more documents. 3. Pick the Recommended level, or Strong for image-heavy reports with a strict limit. 4. Run the compression and download the smaller file. 5. Open it in Word and check images, tables, headers and page breaks. 6. If it is still large, turn off font embedding and accept or reject tracked changes, then save again. Q: Will compressing a Word file change my formatting? A: No. Only embedded pictures and unused media are changed. Fonts, styles, tables, headers, footers and page layout remain exactly as they were. Q: Why is my Word file large even though it has few pictures? A: Check for embedded fonts, long tracked-change histories and embedded Excel objects. These are settings and content inside Word, so turn off font embedding, resolve tracked changes and replace embedded workbooks, then save again. Q: What does the 'Do not compress images in file' option do? A: It tells Word to keep every picture at its original quality when saving. That is useful for print-critical work but makes ordinary documents much larger. You can untick it under File, Options, Advanced. Q: Can I compress an old .doc file? A: Open it in Word and save it as .docx first. The compressor works on the modern package format used by Word 2007 and later. Q: Is there a limit to how many documents I can compress? A: You can add several files in one go. Very large files depend on your device's available memory, since all processing happens locally in the browser. ### How to Resize Your Signature for Online Application Forms URL: https://indiadigital.org/blog/signature-size-online-form/ Sign with a dark pen on plain white paper, photograph it in good light, crop tightly around the signature and save it as a JPEG under the KB limit in your notification. The Photo and signature size optimizer lets you crop, set the pixel size and target KB in one go, entirely in your browser. 1. Check your notification for the signature dimensions, KB range, file format and ink colour instructions. 2. Sign on clean white paper with a black or dark blue pen, as instructed, keeping the signature natural and similar to your usual one. 3. Photograph or scan the signature in bright, even light, holding the phone flat above the paper. 4. Open the Photo and signature size optimizer, select the image and crop tightly around the signature with a small margin. 5. Set the width and height in pixels and a target KB slightly under the limit, choose JPEG and run it. 6. Zoom in to check the strokes are clear and the background is white, then download and upload to the portal. Q: What is the standard signature size for online forms? A: There is no single standard. Each exam, job or government portal sets its own dimensions, KB range and format, and these can change from one year to the next. Always use the values in your current notification. Q: Can I use a signature in blue ink? A: Only if your notification allows it. Many forms specify black or blue ink, and some specify one colour only. Whatever the colour, a bold, dark line on white paper compresses and displays best. Q: My signature file is too small. What should I do? A: Some portals set a minimum size as well as a maximum. Raise the target KB, increase the pixel dimensions slightly, or use a higher quality setting. Do not add a large blank border just to increase the size. Q: Should I scan or photograph my signature? A: Either works. A flatbed scanner gives even light and a straight image, but a phone photo taken flat above the paper in daylight is usually just as good once it is cropped tightly and the contrast is cleaned up. Q: Is my signature uploaded when I use IndiaDigital? A: No. The image tools process files in your browser on your own device, so your signature is not sent to our servers. You can even disconnect from the internet after the page loads and the tool will still work. ### How to Sign a PDF Online Free (and When You Need a DSC Instead) URL: https://indiadigital.org/blog/sign-pdf-online-free/ Open Sign PDF, add your file, then type, draw or upload an image of your signature and place it on the page. This creates a visual electronic signature, which is accepted for many everyday documents such as offer letters, NDAs and internal approvals. It is not a certificate-based digital signature (DSC), so for filings and processes that require a DSC or Aadhaar eSign, use those instead and always check the receiving organisation's rules. 1. Open Sign PDF and add the PDF you need to sign. 2. Create your signature: type your name and choose a style, draw it with a mouse, finger or stylus, or upload a photo of your signature on white paper. 3. Place the signature on the signature line and resize it so it fits naturally. 4. If the document also asks for a date or your printed name, add it with Edit PDF before or after signing. 5. Download the signed PDF and open it to check the signature is in the right place on every page that needs it. Q: Is a signature added with Sign PDF legally valid? A: A visual electronic signature is accepted for many everyday agreements when both sides agree to it, but it is not a certificate-based digital signature. Where a law, regulator or organisation requires a DSC or Aadhaar eSign, it will not be enough. Check with the recipient, and with a lawyer for important contracts. Q: What is the difference between a DSC and Aadhaar eSign? A: A DSC is a digital certificate issued to you by a licensed Certifying Authority, usually kept on a USB token and reusable for its validity period. Aadhaar eSign authenticates you through Aadhaar, typically with an OTP, and uses a short-lived certificate for each signing. Both create verifiable, certificate-based signatures. Q: Can I use Sign PDF for GST or MCA filings? A: No. Filings that require a DSC or Aadhaar-based signing must be completed through the official portal's own signing process. Sign PDF only places a visual signature on the page. Q: Is my signature stored anywhere? A: No. Sign PDF runs in your browser, so your signature and document are processed on your device and not uploaded to our servers. Save your signature image privately if you want to reuse it. Q: Can I sign a PDF on my phone? A: Yes. Open Sign PDF in your mobile browser, draw your signature with your finger and place it on the page. A stylus gives smoother results if you have one. ### How to Split a PDF and Extract Pages: Single Pages, Ranges and More URL: https://indiadigital.org/blog/split-pdf-pages/ To split a PDF, open Split PDF, add the file and choose whether to extract specific pages, save each page as its own PDF, or cut the document into ranges such as 1-5 and 6-12. If you are splitting to get under an email or upload limit, split by size instead. Everything runs in your browser, so the original file is never uploaded. 1. Open the PDF in a reader and note the page numbers you need (use the reader's page numbers, not the printed ones). 2. Open Split PDF on IndiaDigital and add the file. 3. Choose a mode: extract selected pages, split every page into its own file, or split by ranges. 4. Type the pages or ranges, for example 1-3, 7, 10-12. 5. Run the split and download the result (several files arrive together as a ZIP). 6. Open each new PDF to confirm it starts and ends on the right page. Q: Does splitting a PDF reduce quality? A: No. Pages are copied without re-encoding, so text, images and vector graphics stay exactly as they were in the original. Q: How do I extract one page from a PDF? A: Open Split PDF, choose the extract pages option, type the page number and download the new file. You can list several pages or ranges if you want them combined into one PDF. Q: Can I split a PDF so each part is under a certain size? A: Yes. Use Split PDF by size and set the maximum size per part. Try compressing the file first, as a single smaller file is often easier to send than several parts. Q: Why are my page numbers off by a few pages? A: The tool uses the physical position of each page in the file, starting at 1. Covers and front matter numbered in roman numerals shift the printed numbers, so use the page number shown in your reader's toolbar. Q: Can I split a password-protected PDF? A: You need to know the password. Remove it with Remove PDF password, split the file, and then re-encrypt the parts if they still need protection. ### Is It Safe to Upload PDFs to Online Tools? How to Protect Your Documents URL: https://indiadigital.org/blog/is-it-safe-to-upload-pdf-online/ Uploading a PDF to an online tool means sending a copy to someone else's server, where it may be stored, logged or accessed in ways you cannot see. For sensitive documents such as Aadhaar, PAN, bank statements or payslips, prefer tools that process files inside your browser, and verify it yourself by watching the Network tab in your browser's developer tools while the tool runs. Redact what the recipient does not need and password-protect files before sharing. 1. Open the PDF tool's page in Chrome, Edge or Firefox on a computer and let it load fully. 2. Press F12 (or Ctrl+Shift+I, or Cmd+Option+I on a Mac) to open developer tools, then select the Network tab. 3. Click the clear button to empty the list, so you only see what happens from now on. 4. Add a test PDF to the tool and run the task, such as compressing or merging. 5. Watch the list for new requests while it processes. Sort by size or look for POST or PUT requests with a large request payload. 6. If no request carries data close to your file's size, the file was processed locally. As an extra check, load the tool, switch off your internet and try again. Q: Do online PDF tools keep a copy of my file? A: Tools that upload files to a server may keep copies for a period described in their privacy policy, and sometimes in backups or logs as well. Tools that process files in your browser do not receive the file at all. Check the privacy policy and use the Network tab test to see which kind you are using. Q: Is it safe to upload my Aadhaar PDF to compress it? A: It is safer not to upload it at all. Use a tool that compresses in your browser, and consider whether you can share a masked Aadhaar instead, which hides most of the number. Redact any details the recipient does not need before sending. Q: How can I tell if a website processes files in my browser? A: Open your browser's developer tools, go to the Network tab and run the tool on a test file. If no request sends data roughly the size of your file, it was processed locally. Working offline after the page loads is another strong sign. Q: Does HTTPS mean my uploaded file is safe? A: HTTPS protects the file while it travels between your device and the server, so others on the network cannot read it. It does not control what happens to the file once the server receives it. That depends on the service's own practices. Q: Is a black box over text the same as redaction? A: No. A box drawn on top usually leaves the original text in the file, where it can be copied or searched. Proper redaction, such as with Redact PDF, removes the underlying content. Search the file for the hidden text afterwards to confirm it is gone. Q: Should I delete files after using a PDF tool? A: Yes, for anything sensitive. Delete unlocked, unredacted or duplicate copies from your downloads folder, messaging apps and cloud folders once you no longer need them. If you used a tool that uploads, check whether it offers a way to delete your file from its servers too. ### JPG to PDF: Combine Photos and Scans Into One PDF URL: https://indiadigital.org/blog/jpg-to-pdf/ To turn photos into one PDF, open IndiaDigital's Images to PDF tool, add your JPG or PNG files, drag them into the right order and download a single PDF. iPhone photos in HEIC format need converting to JPG first with the HEIC converter. Crop and straighten photos before converting, and compress the PDF if a portal has a size limit. 1. Take or collect your photos, cropping each one to the document edges and rotating it upright. 2. If any photos are iPhone HEIC files, convert them to JPG with the HEIC converter first. 3. Open Images to PDF on IndiaDigital in your phone or computer browser. 4. Add all the JPG or PNG files at once. 5. Arrange them in the order they should appear, for example front of the ID before the back. 6. Create and download the PDF, then compress it if the upload portal has a size limit. Q: Can I convert JPG to PDF on my phone? A: Yes. Open Images to PDF in your phone's browser, add photos from your gallery, arrange them and download the PDF. It works on Android and iPhone without installing an app. Q: How do I change the order of pages? A: After adding your images, drag the thumbnails into the order you want before creating the PDF. The PDF pages follow that order exactly. Q: Why does the tool not accept my iPhone photos? A: Your photos are probably in HEIC format. Convert them to JPG with the HEIC converter first, then add the JPG files to Images to PDF. Q: My PDF is too large for the upload portal. What should I do? A: Run it through Compress PDF and check that the text is still readable. If it is still too large, crop the photos tightly and reduce their resolution before converting again. Q: Can I mix PNG and JPG images in one PDF? A: Yes, you can add both PNG and JPG files to the same PDF. Screenshots are often PNG and camera photos are usually JPG, and both work together. ### PDF to JPG: Turn PDF Pages Into Images for WhatsApp and Slides URL: https://indiadigital.org/blog/pdf-to-jpg/ To convert a PDF to JPG, open IndiaDigital's PDF to JPG and PNG tool, add the PDF and download every page as an image. Choose JPG for photo-heavy pages and small files, PNG for sharp text, diagrams and screenshots, and a higher resolution if people will zoom in or print. To get the original photos inside a PDF rather than whole pages, use Extract embedded images. 1. Decide whether you need whole pages as pictures or just the photos inside the PDF. 2. For whole pages, open PDF to JPG and PNG on IndiaDigital and add your PDF. 3. Choose JPG for photos and smaller files, or PNG for text, charts and diagrams. 4. Pick a resolution that suits where the image is going: lower for chat, higher for print or zooming. 5. Convert and download the images, then open one to check that small text is readable. 6. For original pictures inside the PDF, use Extract embedded images instead. Q: How do I convert just one page of a PDF to JPG? A: Convert the PDF and keep only the image of the page you need. If the PDF is very long, you can first split out the page you want, then convert that smaller file. Q: Should I choose JPG or PNG? A: Choose JPG for photos and when file size matters, such as on WhatsApp. Choose PNG for pages that are mostly text, tables or diagrams, because it keeps edges sharp. Q: Why does my image look blurry on WhatsApp? A: Messaging apps often compress images again when you send them as photos. Convert at a slightly higher resolution, or send the image as a document so the app does not compress it. Q: How can I get the original photos out of a PDF? A: Use Extract embedded images. It pulls out the pictures placed in the PDF at their original quality, rather than rendering whole pages with text around them. Q: Can I convert the image back into a PDF later? A: Yes. Use Images to PDF to combine one or more images into a PDF in the order you choose. The text will be a picture, though, so it will not be searchable unless you run OCR on it. ### PDF Too Large to Email? 3 Free Ways to Send It URL: https://indiadigital.org/blog/pdf-too-large-for-email/ Most free email services, including Gmail and Outlook.com, accept attachments of around 20 to 25 MB in total per message, and the exact figure varies by provider and account. If your PDF is larger, compress it with Compress PDF, split it into parts that each fit with Split PDF by size, or upload it to cloud storage and send a link instead. 1. Check the attachment limit of your email provider and, if possible, of the person receiving it, since their server may accept less. 2. Run the file through Compress PDF on the Recommended level and see whether it now fits under the limit. 3. If you need a specific size, use Target-size PDF and enter a figure a few megabytes below the limit. 4. If the file is still too large, use Split PDF by size to cut it into numbered parts that each stay under the limit. 5. Attach the parts to separate emails, label them clearly (Part 1 of 3, Part 2 of 3) and mention the total number of parts in the first message. 6. For very large files, upload the original to your cloud storage and email a share link with the right access permissions. Q: What is the maximum PDF size I can email? A: Gmail and Outlook.com accept attachments of around 20 to 25 MB per message, but limits differ between providers and work accounts and can change. The recipient's server may also accept less than yours sends, so check both if you are close to the limit. Q: Why is my 20 MB PDF rejected when the limit is 25 MB? A: Email encodes attachments as text, which makes them larger in transit than on your disk. The recipient's mail server may also have a lower limit than yours. Compress the file to well under the limit to be safe. Q: Will compressing a PDF for email reduce its quality? A: Usually not noticeably on screen. Compression mainly reduces the resolution of pictures, which are often saved at far more detail than needed. For typed documents, the text stays sharp because it is real text, not an image. Q: Can I zip a PDF to make it smaller for email? A: Zipping rarely helps much with PDFs because they are already compressed internally, so the saving is usually small. Some organisations also block zip attachments. Compressing or splitting the PDF itself is more effective. Q: Is it safe to compress a confidential PDF online? A: It depends on the tool. IndiaDigital processes files in your browser, so the PDF is not uploaded. Read is it safe to upload PDFs online to learn how to check any tool yourself. ### PowerPoint to PDF: Share Decks and Handouts That Look Right URL: https://indiadigital.org/blog/powerpoint-to-pdf-slides/ Convert PowerPoint to PDF whenever you are sending a deck for someone to read rather than present, because a PDF opens on any phone or laptop and looks the same everywhere. IndiaDigital draws each slide with its theme colours, backgrounds, text, bullets, pictures, shapes and tables, but animations, video, charts and SmartArt are not drawn, so replace those with static pictures first. 1. Open the deck and replace any charts or SmartArt with pictures (copy, then Paste Special as a picture). 2. For slides that rely on animation, split the steps into separate slides or show the final state. 3. Move important speaker notes onto the slide or into a short appendix slide if the reader needs them. 4. Save as .pptx and open the PowerPoint to PDF tool on IndiaDigital. 5. Drop in the file and download the PDF; it is processed in your browser, not uploaded. 6. Flip through every page on a phone and a laptop, then compress the PDF if it is too large to email. Q: Why are my charts missing from the PDF? A: Charts are not drawn by the PowerPoint to PDF tool at the moment. Copy each chart, paste it back as a picture with Paste Special, delete the original chart and convert again. The picture will appear in the PDF exactly as it looked on the slide. Q: Will my animations work in the PDF? A: No. A PDF page is static, so animations and transitions are not included. Slides show their content without the animation, so if animated items overlap, split the steps into separate slides. Q: Can I include speaker notes in the PDF? A: The PDF shows the slides themselves. If readers need your notes, add key points to the slides, include a few appendix slides, or write a short companion document and merge it with the deck. Q: What happens to videos embedded in my slides? A: Video and audio cannot play inside the PDF and are not included. Add a still image and a one-line description, or put a mention of where the video can be found as plain text on the slide. Q: Is the PDF version smaller than the PowerPoint file? A: Often, yes, especially when the deck contained video. If it is still large because of high-resolution photos, use Compress PDF, then open it to make sure the pictures still look sharp. ### Should You Send Your Pitch Deck as PDF or PPTX? URL: https://indiadigital.org/blog/pitch-deck-pdf-or-pptx/ For a first, unsolicited send, a PDF is usually the safer choice: it looks exactly as designed on any device, is hard to edit by accident and tends to be smaller. Send PPTX only when someone asks for an editable file or needs to present it live. Whatever the format, follow the investor's or programme's instructions first and run through a short pre-send checklist. Q: Do investors prefer PDF or PowerPoint? A: Preferences vary from person to person, and there is no universal rule. When no format is specified, a PDF is the safer default because it opens reliably and looks the same on every device. Offer the PPTX if someone asks for it. Q: Will my fonts look right in a PDF? A: Yes, in most cases fonts are embedded in the PDF during export, so the reader sees your typography as designed. Open the exported file and check a few slides to be sure. Q: How big should a pitch deck file be? A: Small enough to attach or upload without trouble. There is no single correct size, but it should sit comfortably under the limit of the email service or portal you are using, which you should check directly. Q: Should I attach the deck or send a link? A: Both work. Attachments are simple and readable offline, while links allow updates and viewing analytics but can add friction if they require sign-up. Many founders send a no-sign-up link or attach a compact PDF. Q: Is it safe to convert my deck online? A: With IndiaDigital, conversion and compression happen in your browser, so your deck is not uploaded to a server. That is worth considering when your deck includes financials or unannounced plans.
