About the tool

What is Watermark PDF?

Watermarks signal status (draft, copy, confidential) or ownership. A diagonal text at 20–30% opacity stays readable without hiding the content underneath. Use the repeated layout to cover the whole page.

Text is drawn as an image, so any language works, including Arabic, Chinese or Cyrillic. Note that a watermark is a visible mark, not protection: someone determined can still edit the file.

Your files stay with you. This tool works inside your browser tab. Nothing you select is uploaded, stored or seen by us.

Pro tips

  • A watermark is visible branding, not security. Do not rely on it to protect secrets.

FAQ

Frequently asked questions

Can I use my logo?

Yes. Switch to “Image / logo”, upload a PNG (transparent works best) and set its width.

Does it support non-Latin text?

Yes. Because the text is rendered as an image, Arabic, Hebrew, Chinese and other scripts work.

Can the watermark be removed later?

It becomes part of the page. It cannot be removed with a click, but this is not a security feature.
