How it works

  1. Choose a PDF.
  2. Type watermark text or upload a PNG/JPEG logo.
  3. Adjust opacity, size, rotation, position and pages in the live preview.
  4. Download the watermarked PDF.

Supported formats

Input: One PDF, plus optional PNG/JPEG logo (transparency supported).

Output: A PDF with the watermark drawn on the chosen pages.

Good to know

  • The watermark is drawn on top of the page; original text stays selectable underneath.
  • Transparent PNG logos keep their transparency — no background box is added.
  • Free account required — no card, no trial, no watermarks added by us.

Questions

Can I watermark only some pages?

Yes. Choose all pages, or enter a list like 1-3, 5.

Will my logo keep its transparent background?

Yes. PNG transparency is preserved, so there's no white box behind your logo.

Is my file uploaded?

No. Your file is processed entirely in your browser and is never uploaded to a server.
