Add a Watermark to PDF Online Free

Stamp text such as DRAFT or CONFIDENTIAL across a PDF, once per page or tiled, with control over opacity, rotation and size. Fully client-side.

How it works

  1. Drop in the PDF you want to watermark.
  2. Type the watermark text, then set its size, opacity, rotation and position.
  3. Optionally tile it across the page, apply, then download.
Privacy & Processing: Watermarking runs entirely in your browser. Your PDF is never uploaded, and the watermark text is never sent to analytics.

Frequently Asked Questions

Can the watermark repeat across the page?

Yes. Tiling repeats it in a grid. The tile count is capped so a very small font cannot generate an enormous file.

Will it obscure my content?

It defaults to a translucent, rotated stamp so the document stays readable, and you can adjust the opacity.

Can I watermark only some pages?

Yes. Apply it to all pages or to a specific range.
