Anonymising a document means removing the details that identify people: names, addresses, contact details and reference numbers. AnonymousPDF scans your PDF and takes them out automatically, so you can share or archive the file without exposing personal data.
Detection combines precise pattern matching for structured data (emails, phone numbers, IBANs, card and ID numbers) with an on-device AI model for names, organisations and places. It is a practical first step for data minimisation under rules like the GDPR — and because everything runs in your browser, the personal data never leaves your device.

Frequently asked questions
What's the difference between redacting and anonymising?
Redacting blacks out specific content; anonymising focuses on removing the personal data that identifies individuals. This tool does both — it finds personal data and removes it from the file.
Does it remove names?
Yes. An AI model running in your browser detects person and organisation names in addition to pattern-based data like emails and IBANs.
Is anything uploaded?
No — your file is processed locally and never sent anywhere.
Will it catch everything?
Automatic detection is very good but not perfect. Always review the result before sharing, especially for unusual names or formats.
