Frequently asked questions
Where does the watermark appear?
The text is stamped diagonally across the center of every page, sized and rotated to fit the page dimensions.
Is my PDF uploaded to a server?
No. The PDF is loaded and stamped entirely in your browser using JavaScript - it never leaves your device.
Can I remove the watermark afterward?
The watermark is drawn permanently into the page content, the same way a printed stamp would be - it can't be toggled off later.
Can I use an image as a watermark instead of text?
This tool only supports text watermarks. For a logo or image stamp, a desktop PDF editor is a better fit.
