Most "free PDF redactors" make you sign up, watermark the result, cap the page count, or push you to a paid plan after one redaction. AnonymousPDF is genuinely free: drop in a PDF, the tool finds the sensitive text, and you download a clean file. No account is created, no email is collected, no result is stamped.
It works because everything runs locally in your browser. There is no server-side processing to pay for, so we have no reason to gate it. The same detection used in paid redaction services — pattern matching for emails, phone numbers, IBANs, IDs and dates, plus an on-device AI model for names — is fully available here, with the original file never leaving your device.
1. Drop your PDF
Choose a file or drag it onto the page. It opens locally — nothing is sent to a server.
2. Automatic detection
Pattern matching and an on-device AI model locate the sensitive text for you.
3. Download or copy
Get a redacted PDF with the text truly removed, or copy the cleaned text.
