What is a PDF Watermark?
A PDF watermark is text or an image overlaid on every page of a document. It identifies ownership, status, or restricts distribution. Common watermarks include CONFIDENTIAL, DRAFT, DO NOT COPY, company names, or personalized recipient notices.
Watermarks serve two purposes: they deter unauthorized sharing by making the document's status visible, and they attribute ownership if the file is redistributed. They don't technically prevent copying, but they make misuse obvious and traceable.
This tool adds text watermarks to PDFs entirely in your browser. No software installation required, no server uploads, no accounts. Just upload, customize, and download.
