Redact a PDF free, without uploading it
Remove names, numbers and addresses from a PDF before you share it, and sanitize the file, in your browser. The document never leaves your device.
How to do it
- Upload the PDF in Files and open it in the PDF app.
- Mark the text or areas to remove.
- Apply the redaction.
- Sanitize the document to clear hidden information.
- Save, then search the saved file for a redacted word to check it is gone.
Why do it here
A document you need to redact is one you should not upload. The PDF opens in the PDF app inside Madosuite’s Linux machine, in your browser. It is not uploaded to us, which matters for contracts, medical letters and anything with a signature on it.
Limits today
- The PDF app is alpha. Always check a redacted file by searching it for the words you removed.
- Editing existing text is not yet reliable; redaction removes, it does not rewrite.
Questions
Is drawing a black box over text enough?
No. A box on top leaves the text underneath, where anyone can copy it. Use redaction, which removes it, then search the saved file to check.
What does sanitizing do?
It clears information you cannot see on the page, so it does not leave with the file.
