How it works
- Add a PDF file and draw boxes over what to redact, page by page
- Every page is rasterized to an image with those boxes burned in, on your device
- Download the redacted PDF — the covered content is gone, not just hidden
Frequently asked questions
Is my file uploaded anywhere?
No — this tool runs entirely in your browser using JavaScript/WebAssembly. Your file is never sent to a server.
Is there a file size limit?
Free accounts can process files up to the limit shown on this page; signing up for Pro raises that limit substantially.
