About the Watermark PDF

Watermark PDF places one text label at the centre of every page. Wording, font size, colour, opacity, and diagonal or horizontal orientation can be adjusted while a first-page preview remains visible.

The watermark is drawn as PDF text using embedded Helvetica Bold rather than baking the page into an image. Existing page content remains intact and selectable.

The same watermark settings apply to all pages. This is a visual ownership or status mark, not access control, encryption, or tamper-proof digital rights management.
