How Watermark PDF works

Add a text watermark to PDF pages online. Control text, size, opacity, rotation and placement while processing the document locally in your browser.

What you provide
A PDF, watermark text, page selection and visual settings.
What AG File Tools returns
A new PDF with the watermark drawn over the selected pages.
Practical limit
The watermark becomes page content. It discourages casual reuse but is not digital-rights management.
