Redact

Mask sensitive information in PDF. Right in your browser. 100% free, privacy protected.

Redact permanently removes sensitive information from a PDF rather than just covering it up. Drawing a black box with an annotation tool leaves the original text sitting underneath, where anyone can select and copy it — a mistake that has caused real leaks. This tool deletes the underlying content in the redacted region and then draws the blackout, so the words are gone from the file, not merely hidden. Redaction is applied in your browser, which matters given the kind of document that usually needs it.

Frequently Asked Questions

Can the redacted text be recovered?

No. The content inside the redacted area is removed from the page's content stream before the file is written, so there is nothing left underneath to select or extract.

How is this different from drawing a black rectangle?

A drawn rectangle is an annotation layered on top. The original text stays in the file and can be copied out or revealed by removing the annotation. Redaction deletes the content itself.

Does it redact scanned pages?

Yes. On a scan the region is an image, and the pixels inside the redaction area are removed rather than covered.

Should I check the result?

Always. Open the output and try selecting text over the redacted areas before you send it. It takes a few seconds and it is the only way to be certain.
