Free PDF Redaction Tool – Black Out Sensitive Information

Yes. Redacted content is permanently removed and replaced with a solid rectangle, so the original text cannot be recovered from the output file. Because this is irreversible by design, always keep your own unredacted copy in case you need the full information later.

Drawing a black box in a basic editor only covers the text visually — the words often still exist underneath and can be copied or extracted. True redaction removes the underlying content and replaces it with a solid block, so there is nothing hidden beneath the mark. This tool performs the latter for genuine protection.

Yes, always. Redaction is permanent and irreversible by design, so the hidden text cannot be recovered from the output file. Keep your own unredacted original in a safe place in case you need the full information later, and only share the redacted version externally.

Text search redaction targets the document's text layer. Information that is part of an image — such as a signature or a scanned number — is not found by a text search, so you should manually draw a redaction box over those areas. Always review the final file to confirm nothing visible remains.

Yes. The redaction runs entirely in your browser, so your document is never uploaded to a server and nothing is stored online. This is essential for sensitive files like legal records and medical documents, which stay on your own device throughout the process.

Use the search-and-redact-all feature to catch every instance of a name or number, then review the whole document carefully, including headers, footers, and the edges of pages. Confirm that redacted areas cannot be selected or copied. For anything embedded in images, add manual area redactions before downloading.

Yes. The tool works in mobile browsers on Android and iPhone, so you can black out sensitive details directly from your phone before sharing a document. Upload the file, search for or mark the content to hide, apply the redaction, and download the sanitized PDF.
