Watermark a PDF on Mac
Watermark a PDF on your Mac directly in the browser. Drag files from Finder, choose your options, and download a clean result. Works in Safari, Chrome, and Firefox on macOS.
macOS has Preview for editing a single PDF, but watermarking multiple files is clunky and easy to get wrong. For a quick, reliable job, a browser-based tool is simpler — especially on machines where you'd rather not install extra software.
Drag files straight from Finder into the tool window, choose your options, and download the result in seconds. Works seamlessly in Safari, Chrome, and Firefox on any recent version of macOS.
