PDF PII Detector

Scan a PDF for SSNs, credit-card numbers, email addresses, and phone numbers — report locations with redaction-ready coordinates so you can target a redaction pass.

How does the PDF PII Detector work?

Extract every page of a PDF as text and run regex patterns to detect common PII: US-format Social Security Numbers (NNN-NN-NNNN), credit-card numbers (with Luhn check), email addresses, and US/international phone numbers. The report masks the matches before display so you can share the report itself without leaking the PII. Use this as a first-pass before sending a document externally — combine with Permanent Redaction to actually remove what was found.

🔒 Security & Privacy

All processing happens on your device. Your files never leave your browser, never touch our servers, and are not stored anywhere. Close the tab and the file is gone.

📱 Use it on any device

Works in any modern browser — Mac, Windows, Linux, iPhone, Android, and tablets. No installation, no app to download. Just open the page and start.

⚡ Quick & easy

Drag, drop, click. Most files process in seconds, not minutes. No watermarks added to your output, no per-day limits, and the tool always shows the result before asking you to download.

🎁 Always free, no signup

Free to use, every time. No account creation, no email required, no “trial” that converts to a paid plan. We make money from ads so you don’t have to pay.

Frequently asked

A PII report that prints the actual numbers IS itself PII. Masking SSNs to ***-**-1234 lets you see "yes this exists" + the last-4 for cross-referencing without the report itself being a leak.
