How to redact pdf

Add a PDF.
Draw boxes over what must be hidden.
Download. Pages with redactions are rebuilt as images, so the hidden text is truly removed.

Questions

Is my file uploaded?

No. This tool runs inside your browser with code loaded from signofficially.com. Your file is read, changed and saved on your own device. Open your browser's developer tools, choose the Network tab and use the tool: no file leaves your computer.

Is the text really removed?

Yes. Any page you redact is rebuilt from a picture of the page with the black boxes burned in, so the original text underneath no longer exists in the file.

Is it free?

Yes. Every on-device tool is free to use, with no limits. Paid plans add unlimited signature requests, teams and more.
