Why use DoMyPDF’s Redact PDF

Private by design
It runs inside your browser, so your file never leaves your phone or computer, and it keeps working on a slow connection.

Use it on iPhone, iPad, Mac or a Windows PC, in any modern browser. Nothing to install, and you can add DoMyPDF to your home screen.
Quality first
Gives you the result in seconds, with no watermark added to your pages.
Tips for the best result
- Redact PDF saves a new copy; your original file isn’t changed, so you can always start again.
- Working on a phone? Large PDFs with many photos are quicker if you compress them first.
- Combine tools for bigger jobs: merge files, then add page numbers, then compress the result.
- Every page stays sharp: text and pictures are kept at their original quality unless you choose to compress.
