How to Automatically Redact Sensitive PII from PDFs Securely

If you work in HR, legal, or compliance, you know the absolute nightmare of manually redacting documents. Missing a single Social Security Number (SSN) or credit card number can lead to a massive data breach.

But here is the scary part: most people use "free" online PDF editors to redact documents. By uploading an unredacted document to a random cloud server, you have already compromised the data!

The Solution: 100% Local AI Redaction

We built the Auto Redact PDF tool using WebAssembly. This means the entire redaction engine is downloaded directly into your Chrome/Edge browser. When you select a document, it never leaves your computer.

How it works:

1. Select your PDF: Choose the document containing sensitive PII.
2. Choose what to redact: Select Email Addresses, Phone Numbers, SSNs, Credit Cards, or type your own custom Regex patterns.
3. Instant Blackout: Our local engine scans the text layer, draws permanent black boxes over the sensitive data, and strips the underlying text so it cannot be copy-pasted.
