Add watermark to PDF
Stamp an image or text over your PDF in seconds.
What Watermark does
Watermark PDF overlays text or an image onto every page — a draft notice, a company mark, a confidentiality warning. You control the position, rotation, opacity and size, so the mark can be a subtle corner stamp or a bold diagonal across the page. Because it is applied on your device, an unreleased document can be watermarked before it is ever shared.
How to watermark
- Select the PDF.
- Choose a text or image watermark and adjust position, angle, opacity and size.
- Press Add watermark and download the result.
Privacy
The mark is composited onto each page locally. Neither the PDF nor your logo is uploaded.
Questions
Can I use a logo instead of text?
Yes — switch the watermark type to image and pick a PNG. Transparency is preserved.
Can the watermark be removed afterwards?
It is drawn into the page content, so it cannot be dismissed as a layer in a viewer. It is not a cryptographic guarantee, but it is not a toggle either.
Does it apply to every page?
Yes, by default the watermark is placed on all pages.
