About This Tool
The Auto PII Detector is a specialized privacy tool designed to automatically identify and redact Personally Identifiable Information (PII) from your PDF documents. It saves you from the tedious task of manually searching for and blacking out sensitive data.
Using advanced scanning patterns, the tool detects email addresses, phone numbers, Social Security Numbers (SSN), and credit card details. You can review the found items and choose exactly what to redact with one click.
In line with our privacy mission, all scanning and redaction happen locally in your browser. Your sensitive files never leave your device.
