Watermark PDF
Mark a document as a draft, a copy or confidential. Add a text watermark diagonally, across the centre or along the bottom of every page or selected pages.

A text watermark discourages casual reuse but can be removed by someone determined. It is not a security feature.

Choosing a watermark that stays readable
A watermark should be noticed without hiding the document. Around 20 to 30% opacity works for diagonal text across a page of writing; go lighter on pages with images. For a discreet ownership line, choose “Small, along the bottom” and use your name or company.
Questions about the Watermark PDF
Can a watermark be removed?
A determined person with PDF editing software can remove it. Treat a watermark as a label and a deterrent, not as protection.
Which characters can I use?
English and Western European letters, digits and common punctuation. Other scripts are not supported by the built-in PDF font.
