I want to add a watermark to a PDF
Mark a document as a draft, flag it confidential, or brand it with your logo, across every page, in seconds.
To watermark a PDF, use a watermark tool: overlay text like DRAFT or CONFIDENTIAL, or a logo, across every page, and set the opacity, angle and position. Our tool runs in your browser, so the document is never uploaded, and it adds no watermark of its own. It's the way to brand or mark the status of a document before sharing.

Apply and download
The watermark is stamped on every page. For sensitive files, also password-protect the PDF before sharing.
- Making the watermark so dark it hides the text underneath. Keep it semi-transparent.
- Treating a watermark as security. It discourages misuse but doesn't protect a file. Add a password for that.
- Using a tiny corner mark when a diagonal, page-spanning watermark is far harder to crop out.
