Frequently Asked Questions

Is my file uploaded to a server?

No. All processing happens entirely in your browser using JavaScript and WebAssembly. Your file never leaves your device — zero network requests are made with your document data.

How does OCR redaction work?

For PDFs and images, Tesseract.js (running locally in your browser) scans for text. When a match is found, the exact pixel region is overwritten with a black rectangle — the original text is destroyed, not just hidden.

What PII patterns are detected automatically?

Built-in patterns include Social Security Numbers, credit card numbers, phone numbers, email addresses, and Canadian passport numbers. You can also add custom text targets (names, case IDs, etc.).

What happens to my file after redaction?

The redacted output is held in browser memory as a temporary Blob URL. After 10 minutes of inactivity, all data is automatically wiped and the page reloads. You can also click "Start Over" at any time.

Does PDF redaction preserve the original format?

Redacted PDFs are output as PNG images (one per page). This ensures the redaction is permanent — text cannot be copied from behind the black bars. The trade-off is the output is image-based, not searchable.

Is 2redact free to use?

Yes. 2redact is completely free with no account required, no file size limits enforced by us (your browser's memory is the only constraint), and no usage caps.
