Watermark PDF
Mark a document before it goes out the door.
A watermark sets expectations about a document at a glance: that a draft isn't final, that a copy isn't the original, or that something shouldn't be forwarded. It is a social signal more than a security control, and that is exactly what most documents need.
Stamp text at any angle and opacity, or place your own logo. Tile it across the page for the classic diagonal wash, or anchor it to a single position for something subtler.
How to use it
- 01Drop in the PDF.
- 02Choose a text watermark and type it, or switch to Image and add a PNG or JPG.
- 03Set the opacity, angle and position — or turn on tiling to repeat it across the page.
- 04Choose which pages get the watermark, then apply and download.
Frequently asked questions
Can the watermark be removed by someone else?
Yes, with effort. It is drawn into the page content, so removing it cleanly is difficult but not impossible. Treat a watermark as a clear label, not as protection — if you need to restrict what people can do, add a password and permissions instead.
Why did some characters disappear from my text?
The built-in PDF fonts cover Western European characters only. Accented Spanish, French and German text is fine; other scripts cannot be drawn and are left out, and the tool tells you when that happens.
Can I watermark only some pages?
Yes. Select the pages you want in the grid; with nothing selected, the watermark goes on every page.
