Watermark PDF
Stamp your PDF with a watermark — free and private.

Frequently asked questions
Can I use my logo as a watermark?+
Yes. You can add an image watermark such as a logo, or use custom text like Confidential or Draft.
Does this tool add its own watermark?+
No. Only the watermark you choose is applied — there is no forced branding on your file.
Are my files kept private?+
Yes. The watermark is applied in your browser, so your PDF is never uploaded.
