Add a watermark to a PDF

Stamp CONFIDENTIAL, DRAFT or your name on every page.

The watermark is added as real text on each page, centred and diagonal by default, at the opacity you choose.

How to use it

  1. Choose your PDF file.
  2. Pick the options you want.
  3. Press the button to add the watermark, then download the new PDF.

Questions

Are my files uploaded to a server?

No. The tool runs entirely in your browser using JavaScript, so your files never leave your device. You can even disconnect from the internet after the page loads and it keeps working.

Is it free?

Yes, free with no sign-up, no watermark and no daily limit.
