How to use Watermark PDF

  1. Choose one or more PDFs.
  2. Add a text or image watermark and set its appearance, page range, position, and layer.
  3. Preview placement and download the watermarked PDFs.

What you can do

  • Text and image watermarks
  • Opacity, rotation, positioning, and tiled repetition

Bundled text fonts support Latin, Greek, and Cyrillic. Unsupported glyphs are rejected rather than silently substituted.

Useful details

Can I add a text or image watermark to multiple PDFs?

Yes. Choose text or artwork, position, size, opacity, rotation and selected pages. You can repeat a watermark in a tile pattern and place it above or below existing content.

Are my documents uploaded?

No. Document processing happens in your browser. Files, passwords, signatures, and editing history are not uploaded or stored by Paperlight. The public site uses Vercel Web Analytics for page-view statistics.

What limits should I know about?

Bundled text fonts support Latin, Greek, and Cyrillic. Unsupported glyphs are rejected rather than silently substituted. Jobs accept up to 100 MB of combined input and 500 pages, subject to additional image and memory limits.
