Redact a PDF
Import the PDF, draw black rectangles over the areas to hide, then download: every redacted page is flattened, so the masked text becomes unrecoverable — unlike a black box placed on top, which leaves the text intact underneath. Everything happens in your browser, nothing is uploaded.
Frequently asked questions
Is the redaction permanent — can the hidden text be recovered?
Yes, it is permanent. Each redacted page is flattened to an image, so the text under and around the mask is actually removed from the file — unlike a black box drawn on top, which leaves the original text intact and recoverable underneath.
Is this tool really free?
Yes — completely free, with no sign-up, no ads and no artificial limits.
Are my files kept or shared?
No. Processing happens on our servers, then the file is deleted immediately and an automatic cleanup removes any residue. Nothing is stored or sold.
