Why Add a Watermark to a PDF?

A watermark is a semi-transparent overlay โ€” typically text like "CONFIDENTIAL", "DRAFT", or your business name โ€” applied across every page of a document. Watermarks serve several purposes: they indicate document status (draft vs final), assert ownership of the content, deter unauthorized sharing, and identify the intended recipient when sending personalized copies.
