What Is a PDF Watermark?
A watermark is a visible text label added on top of a document to show ownership, status, or confidentiality. Common examples include “CONFIDENTIAL”, “DRAFT”, “SAMPLE”, “COPY”, or a company name/logo. Watermarks help discourage unauthorized sharing, protect branding, and clearly communicate document status.
