What is a PDF Watermark?
A watermark is a semi-transparent text or image overlaid on document pages. It's commonly used to indicate document status (DRAFT, CONFIDENTIAL), protect intellectual property, or brand documents with company information.

Tips
An opacity of 0.2-0.3 works well for most documents — visible enough to serve its purpose but not so dark that it interferes with reading the content.
