How to convert Add a watermark to a PDF
- Drop your PDF into the box above.
- Type the text or add a logo, then choose colour, opacity and layout.
- Click Add watermark and download.
Text in any language, or your logo
The watermark text is drawn by your browser, so accents, Cyrillic and other scripts work without hunting for fonts. A logo works best as a PNG with a transparent background.
Frequently asked questions
Can the watermark be removed?
It's drawn onto every page as part of the content. Someone with a PDF editor could still delete it, as with any watermark; it deters copying rather than preventing it.
Are my files uploaded anywhere?
No. The conversion runs inside your browser on your own device. The files are never sent to a server, so nobody else can see them, and they're gone when you close the tab.
