PII Text Redaction Tool

Strip personal data out of text

Before sharing a log, a document or a dataset, personal data often has to be removed. This tool redacts common PII from text, emails, phone numbers, IP addresses, credit card numbers, PAN and Aadhaar, so you can share text without exposing the individuals in it.

Why local redaction is essential

Redacting personal data is pointless if you have to upload the data to a service to do it, because that upload is exactly the exposure you are trying to prevent. Doing it in the browser means the sensitive original never leaves your machine. The tool recognises the patterns of common identifiers, structured things like card numbers and phone numbers have recognisable formats, and replaces them, turning a document full of PII into a shareable one. Pattern-based redaction catches the well-formed identifiers reliably; always review the result for anything unusual it could not recognise.

Redact before you share

The tool runs entirely in your browser, so nothing you paste is uploaded, which is exactly what you want when the input is your own security-sensitive data.
