Watermark PDF — Stamp Every Page With Custom Text
Watermarking a PDF is the easiest way to mark a document as confidential, draft, or proprietary, and to discourage unauthorized redistribution. Our Watermark PDF tool stamps a custom text watermark across every page of your file with full control over color, opacity, font size, rotation, and position.
Whether you're a lawyer marking a contract as DRAFT, a designer protecting concept work with your brand name, an HR team labelling internal documents as CONFIDENTIAL, or a publisher releasing a watermarked review copy, this tool gives you the precision and the speed of a desktop app — entirely in the browser.
You can place the watermark in any of nine positions, or enable diagonal tiling to repeat the watermark across the entire page in a covering pattern that's much harder to crop out. Opacity and color let you choose between a subtle background mark and a loud, attention-grabbing stamp.
Files are processed securely on our servers using the same trusted PDF engine that powers our Edit PDF and Sign PDF tools. Original page content, fonts, and images stay untouched — only the watermark layer is added.
