About this tool

Watermark PDF draws your text across each page. You control the text, opacity, size, rotation and position, so a watermark can be a subtle diagonal stamp or a clear header label.

A watermark is not a security control. It marks a document visually, but anyone with a PDF editor can remove it. Use Protect PDF when access needs to be restricted.

Privacy

This tool runs entirely in your browser. Your file is read from disk by the page, processed with WebAssembly and JavaScript on your device, and the result is created locally. Nothing is uploaded to a PDFYoga server.

FAQ

Can I use an image watermark?
The first version supports text. Image watermarks are planned.
Does it apply to every page?
Yes, with an option to limit it to a page range.
Does a watermark protect my file?
No. It is a visual marker, not encryption. Use Protect PDF for access control.
When is this tool available?
