Redact PDF — frequently asked questions

Is redacted content really removed, or just covered with a black box?+

Really removed. The page is rendered as a flattened image with the box burned in, so there's no text layer left underneath to copy or search.

Can I undo a redaction after downloading?+

No — once applied and downloaded, the redaction is permanent for that file. Keep your original if you might need it again.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The AI tools that used to send extracted text to a server are currently disabled.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
