About this tool
Watermark your PDF with text or an image. Control position, rotation, opacity, size, tiling and which pages. Free and private.
Because everything is processed locally with your browser’s own power, there is no upload wait, no file size queue and no risk of a server keeping a copy of your document.
Frequently asked questions
Is Add Watermark free?
Yes – Add Watermark is free, with no sign-up and no watermark. Free visitors get 5 runs across all tools every 2 hours; Pro (coming soon) removes the limit and the ads.
Are my files uploaded anywhere?
No. Add Watermark runs entirely in your browser, so your PDF never leaves your device and nobody else can see it. The only exception is the optional “Copy link” button: if you click it and confirm, that one file is uploaded and kept for 2 hours so you can send a download link, then deleted automatically.
Does it work on my phone?
Yes. It works in any modern mobile or desktop browser. Very large files need enough free memory on your device.
