About this tool
This tool stamps a customizable text watermark onto every page of your PDF. You control the wording, font size, transparency, angle, and color — making it useful for marking drafts, confidential documents, or pre-release materials. Processing happens entirely in your browser using pdf-lib, so your documents stay private and never touch a remote server.
