Redact a PDF properly

A black box drawn over text often leaves the text underneath, and it can be copied straight back out. Here, a page with redactions is rebuilt as a picture with the areas blacked out, so nothing under them survives.

Good to know

A redacted page becomes a picture, so its words can no longer be selected or searched. Only the pages you redact are changed this way.

Our guide to redacting a PDF properly covers the common mistakes and links to official guidance.

Questions

Can the redacted text be recovered?

Not from the saved file. The page is redrawn as a picture with the areas filled black, and the original text and drawing on that page aren’t carried over.

What about White-out?

White-out covers something in white so you can type over it. It’s for tidying a page, not for hiding information: use Redact for that.

Are my files uploaded?

No. The editor runs in your browser and opens files straight from your device. Nothing is sent to a server, so there is nothing for anyone else to see or keep.
