Take it step by step
- Work on a copy and identify the exact information you are permitted and required to remove.
- Check text, pictures, QR codes, headers, footers and attachments manually.
- Apply actual removal rather than drawing an opaque shape.
- Inspect the exported file independently and check hidden content before sharing.
A situation to try.
Use a synthetic document with a fake identifier repeated in a header and an image. Confirm both appearances are removed; do not use someone’s real identity document as a public example.
Use the tool’s synthetic example first where available. The example here explains a decision; it is not a reported benchmark result.
Before you call it done.
- Search and copy text around every redacted region.
- Inspect images, attachments and metadata.
- Do not rely on a single detection pattern.
Know the limits.
This guide does not certify legal compliance or guarantee detection of every identifier. Sensitive releases need an independent recovery review.
This tool’s current boundary: Rebuilds selected pages from pixels. Searchable text, links, forms and signatures on those pages are lost.
Evidence and scope
Technical source guidance and task-specific output checks. These do not establish that every file, browser or device passes.
Use the checks above on your own exported result. A source explains the format or mechanism; it is not proof that this export preserved every feature.

Automatic PII redaction
Find possible identifiers and review removal page by page.
On your deviceWhy use it: Review local detection suggestions.
Before you start: Automation can miss identifiers; review every page.
Redact PDF
Remove reviewed regions in a rasterized PDF copy.
On your deviceWhy use it: Remove reviewed regions from an exported copy.
Before you start: Independently attempt recovery before sensitive sharing.
Preparation tools process locally. Official service links take you to the authority’s website. Inspect any exported copy before sharing it.
