How it works
The text is drawn diagonally across the center of every page at the opacity you choose, sized relative to the page so it works on both portrait and landscape documents. The preview shows an approximation of the final placement and opacity.
Common uses
- Marking draft documents as "DRAFT" or "CONFIDENTIAL" before sharing
- Adding a company or copyright notice across sample documents

Frequently asked questions
Can I use an image as a watermark instead of text?
Not currently — this tool adds text watermarks only.
Can the watermark be removed later?
It becomes part of the page content, the same as any other PDF editing tool's watermark, so it isn't designed to be removed afterward.
