PDF Watermark.
Add a visible text watermark to all pages of a PDF.
How to use PDF Watermark
Choose a PDF, enter watermark text, select opacity and size, then save.
How it works
Watermarking adds visible text over page content; it is not encryption or copy protection. Standard Latin characters are supported, with rotation and opacity controls. Unsupported scripts are rejected rather than exported as broken glyphs.
Example
Add DRAFT across every page before sharing a review copy.
