PDF Watermark
PDF Watermark is a free online tool for adding text or image watermarks to PDF files. Customize the content, font size, color, opacity, rotation, and tiling — commonly used for copyright notices, confidentiality labels, and "for specific use only" stamps.
Processing happens entirely in your browser; your PDF is never uploaded to a server, so sensitive documents like contracts and reports are safe. Free, with no registration.

- Choose a text or image watermark and set its style (opacity, angle, tiling)
- Preview the result in real time and fine-tune

FAQ
Is my PDF uploaded when adding a watermark?
No. Everything is processed locally in your browser, making it safe for contracts and other sensitive files.
What watermark types are supported?
Custom text and image watermarks, with adjustable size, color, opacity, rotation, and tiling density.
Is it free? Any page limits?
Completely free with no page or usage limits, and no tool watermark is added to your output.
Will the watermark blur my PDF?
No. Watermarks are overlaid as vectors; the original content and sharpness are unchanged.
