Censoring a PDF should mean the hidden text is actually unreadable — not just covered by a box you can copy underneath. AnonymousPDF removes the sensitive content from the file entirely and rebuilds the page, so censored information cannot be selected, searched or recovered.

It automatically detects what to censor — names, organisations, emails, phone numbers, IBANs, IDs and dates — and replaces each with a neutral placeholder. All of it happens in your browser; the original document never leaves 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.

Frequently asked questions

Is the censored text recoverable?

No. The page is rebuilt, so the original text is removed from the file rather than hidden behind a box.

What gets censored automatically?

Names and organisations, emails, phone numbers, IBANs and cards, IP addresses, ID and case numbers, and dates.

Do I have to upload my file?

No — everything is processed locally in your browser.

Is it free?

Yes, free with no account and no page limit.
