Real redaction removes the text — it doesn't just cover it
Redact PDF lets you permanently black out confidential text and images in a PDF without installing Acrobat or uploading a single byte. Draw redaction boxes over any area, or use Find & Redact to auto-mark every email, phone number, ID or custom phrase across the whole document. Its Secure Flatten mode rebuilds each page as a flat image, so the hidden words are truly deleted from the file, not merely covered by a black rectangle that can be copied out later. Because everything runs on your device, it's genuinely safe for contracts, bank statements, medical records and legal discovery.
The most common redaction mistake is drawing a black rectangle over text in a regular editor and thinking the information is gone. It isn't: the words still live in the file underneath the box and can be copied straight out or revealed by deleting the shape, a mistake that has leaked court filings, government reports and corporate contracts. This tool's default Secure Flatten mode avoids that trap entirely. It renders each page to a high-resolution bitmap, burns the black boxes onto that image, and rebuilds the PDF from the flattened images, so there is no text layer left beneath a redaction to recover. What you black out is genuinely deleted from the document.
