Add a watermark to a PDF

Mark your documents “Confidential”, “Draft” or with your logo: the watermark is composed in the local editor and applied to the chosen pages — the file is never sent.

FAQ

Are my files uploaded to a server?

No. Processing runs locally in your browser; nothing is transmitted.

Text or image watermark?

Both: text with adjustable position and opacity, or an image (logo) placed on the pages.

Is the watermark permanent?

It is embedded in the exported PDF; the source file is never modified.

  1. Drop your PDF — it opens in the editor
  2. Configure the watermark (text or image, position, opacity)
  3. Export the watermarked PDF
