What is the Watermark PDF?
A watermark discourages copying and makes the status of a document obvious. It is drawn as semi-transparent text on top of each page.
The watermark font covers Latin-script text, including accented letters such as é, ü and ñ. Cyrillic, Greek, Asian scripts and emoji are not supported.
A watermark is not tamper-proof: anyone with a PDF editor can remove it. Combine it with password protection for sensitive documents.
