Watermarks that
look professional

A good watermark is visible but not distracting. Set the text, opacity, and angle, and we apply it cleanly to every page.

1

Text or image watermarks

Add a 'Confidential' or 'Draft' stamp, or upload your logo. Position it anywhere and set the transparency to taste.

2

Apply to one page or all

Watermark the entire document in one move, or target specific pages. The result is consistent across the whole file.

3

Baked into the PDF

The watermark becomes part of the file, so it shows and prints correctly in every reader on every device.
