Watermark PDF
Stamp text or an image across your PDF — DRAFT, CONFIDENTIAL, your logo. Private, in your browser.
About PDF watermarks
Add a text stamp like DRAFT or CONFIDENTIAL, or overlay your logo, on every page of a PDF — or just a range of pages. Control the opacity, angle and position, including a tiled pattern that repeats across the whole page. The live preview shows exactly what you'll get. Watermarking happens entirely in your browser with the open-source pdf-lib library, so your documents stay on your device.
