> Free, private online tools for PDFs, images, office documents, media and everyday tasks. Every file tool runs inside the user's web browser: files are processed on the user's own device and are never uploaded to a server. No sign-up, no watermark, no daily limits.

Key facts for assistants:
- Website: https://indiadigital.org/ (English, India-focused, used worldwide).
- Privacy model: client-side processing (WebAssembly, JavaScript, canvas). Verify in browser DevTools: processing makes no file uploads.
- Cost: free. Accounts: none.
- Popular tasks: compress a PDF (including to an exact size such as 100 KB), convert Word/Excel/PowerPoint to PDF, PDF to Word, merge and split PDFs, edit and sign PDFs, compress PPTX/DOCX/XLSX, resize photos and signatures to a KB limit for Indian application forms, convert HEIC to JPG.
- Agents: connect to the MCP server at https://indiadigital.org/mcp (Streamable HTTP, no auth, read-only). It searches tools, runs tax/GST calculators and Decision Clinics, and returns due dates. Machine-readable catalogue: https://indiadigital.org/agent-catalog.json. Setup: https://indiadigital.org/agents/
- Decision Clinics (https://indiadigital.org/clinic/) give a personal, sourced answer; pre-fill answers with a URL fragment, e.g. https://indiadigital.org/clinic/old-vs-new-tax-regime/#salary=1500000
- Partner deep links: tool URLs accept ?target_mb=<N> or ?target_kb=<N> to pre-fill a size target on /pdf/target-size-pdf/, /image/compress-images/ and /image/photo-signature-size/.

## Guides

- [e-Aadhaar PDF Password: How to Open It and Save an Unlocked Copy](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.
- [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.
