What is Redact PDF?
Simply drawing a black box over text in a PDF viewer doesn't actually remove it — the original text is often still selectable underneath. Proper redaction permanently deletes the covered content from the file, not just visually hides it.
Mark the areas you want redacted, and this tool removes that content entirely from the underlying document, so it can't be recovered by copying, searching, or opening the file in another program.

When to use it
Legal teams redact a client's personal details from a document before it's filed publicly. HR departments redact salary figures from an internal report before sharing a summary more broadly.
Healthcare administrators redact patient identifiers from a case study document before using it for training, and journalists redact a source's identifying details from a leaked document before publication.
Tip: Double-check by searching the downloaded PDF for the redacted text afterward — a properly redacted file should return no results, confirming the content was actually removed rather than just covered.

Redact PDF – frequently asked questions
Is redacted content actually removed, or just hidden visually?
It's genuinely removed from the file — the underlying text or image data no longer exists in the document.

Can I undo a redaction before downloading?

Does redaction work on scanned documents?

Will the redacted areas be visible as black boxes?
Yes, redacted areas appear as solid black boxes in the final document, clearly indicating removed content.
