Accepts a PDF and places opaque redaction marks over selected areas before exporting a new copy.
Redact PDF
Permanently black out sensitive areas — entirely in your browser.
A black box drawn in a PDF viewer often just sits on top of the text underneath — the original content is still selectable and copyable beneath it. Redact PDF actually flattens the page, so what's covered is gone for good, not hidden.

Each page loads as a preview you can review.
⚙
Mark what to redact
Draw a box over each area of sensitive text or images, on any page.
↧
Redact and download
Every marked area is permanently blacked out in the downloaded file.
Limitations and quality
Review the exported file carefully: visual redaction is intended to cover content, but it is not a substitute for a specialist legal redaction workflow when hidden metadata or compliance matters.
Practical example
Cover an account number or personal address before sending a document to someone who does not need that information.
Troubleshooting
Zoom in before placing marks, cover the complete sensitive area, then reopen the exported PDF and try selecting or copying the covered text to verify the result.
Processing happens in your browser. Keep the original file until you have opened and checked the downloaded result.
Frequently Asked Questions
01Is the redacted content really removed, not just covered?⌄
Yes — the page is flattened so the covered content can't be recovered by selecting text or lifting the black box in another PDF editor.
02Can I redact different areas on different pages?⌄
Yes — step through the pages and add as many redaction boxes as you need on each one.
