- Auto-detects SSN patterns (XXX-XX-XXXX and XXXXXXXXX)
- Also removes names, addresses and dates of birth if needed
- Verifies zero extractable matches remain after redaction
- Works offline after first load
Frequently asked questions
How does QuietKit redact PDFs?▼
QuietKit runs MuPDF inside your browser as WebAssembly. When you apply redactions, it removes the selected text, images and metadata from the actual PDF bytes, then re-verifies that nothing extractable remains.
Do my files leave my device?▼
No. The PDF is loaded into browser memory and processed locally. No bytes are uploaded to any server.
Is the redaction reversible?▼
No. Once you download the redacted file, the removed content is gone from the document. Keep a backup of the original if you may need it later.
What can I redact?▼
You can draw manual rectangles, search for a term, or use preset patterns (SSN, email, phone, credit card). Each match becomes a permanent redaction region.
Is there a file size limit?▼
Currently the tool is tested up to roughly 50 MB and ~200 pages. Larger files may work but are not guaranteed.
Can I use it offline?▼
Yes. After the page loads once, the WASM engine and worker are cached. You can disconnect from the internet and keep redacting.
