Your file is processed in your browser and is never uploaded.
Whether it is a contract, a letter, an invoice or an official notice, sensitive details often need to be removed before you pass it on. AnonymousPDF detects that data automatically and removes it from the document for good — not just visually with a box, but from the file itself.
It recognises emails, phone numbers, IBANs and card numbers, IP addresses, ID and case numbers, and — via an on-device AI model — names, organisations and locations. Processing happens entirely on your device, so confidential documents never leave your browser.

Pattern matching and an on-device AI model locate the sensitive text for you.
