About Watermark PDF

What this tool does

Watermark PDF stamps a text watermark across your pages, with adjustable opacity and rotation.

How to use it

Upload your PDF.
Enter the watermark text and set opacity.
Download the watermarked PDF.

How it works

The watermark text is drawn diagonally onto every page with pdf-lib at the opacity you choose, so it sits over the content without hiding it.

Important considerations

Text watermarks only — image/logo watermarks are not supported here.

Privacy

Your PDF is processed entirely in your browser. The file is never uploaded to a server, which makes this safe for confidential contracts, statements and personal documents.
