Redact PDF
Black out sensitive text in your PDF documents
Redact sensitive information in a PDF
Before a document goes out, certain details often need to disappear — account numbers, addresses, names, salaries or other personal data. Redact PDF lets you black out the parts you want to hide, so you can share a document responsibly without exposing private information.
Proper redaction matters for legal disclosures, freedom-of-information responses and any time you must release a document while protecting the people and details mentioned in it.
How to redact a PDF
Upload your PDF, mark the areas you want to conceal, and download the redacted document. Always review the result carefully before sharing to confirm every sensitive detail is covered.
Processed privately
Redaction is applied in your browser, so your document is never uploaded or stored. The information you are protecting never leaves your device.
