Watermark PDF
Add a diagonal watermark such as DRAFT or CONFIDENTIAL to every page of a PDF.
What it does
Watermark PDF changes which pages a PDF contains, or how they sit, and leaves everything else alone. The page content is copied rather than re-encoded, so nothing is recompressed and no quality is lost between the file you drop in and the one you download.
When you need it
Typically when a document carries pages that should not be shared — an internal cover sheet, a duplicated scan, an appendix meant for someone else — or when a scanner produced pages sideways or out of order.
Limits and caveats
Your original file is never modified: you always download a new copy. Encrypted PDFs have to be unlocked before they can be edited, and a scan is still a scan afterwards — the pages move, the text inside them stays an image. Everything happens in your browser, so the file never leaves your device.

Frequently asked questions
- Can the watermark be removed later?
- It's drawn into the page content, so it isn't a simple toggle to undo.
- Do my files get uploaded?
- No. This tool runs entirely in your browser, so the file never leaves your device.
