PDF Watermark
Add a text watermark to every page of a PDF locally in your browser.
The watermark is drawn on top of the existing page content. It does not flatten the page or prevent the mark from being removed by another editor.
How the watermark is applied
Each page receives the same semi-transparent diagonal text, sized from the page width. The original pages, text, and images are kept. Encrypted PDFs may be rejected.
