Add text or image watermarks to a PDF, adjust opacity, rotation, and placement, then create a new PDF in your browser.
Text or image watermarks
Enter text with a font size and color, or choose a PNG or JPEG image. Transparent PNG files keep their transparency.
Placement for every page size
Choose top left, top center, top right, center, bottom left, bottom center, or bottom right. Each page uses its own dimensions, and you can target selected pages.

Frequently asked questions
Is my PDF uploaded or stored?

PNG and JPEG are supported, including transparent PNG files.
Can I watermark only some pages?
Yes. Choose Custom pages and enter values such as 1-5, 8, 10-15.
Will different-size or landscape pages be misplaced?
The tool calculates placement from each page's CropBox or MediaBox dimensions, including mixed sizes and landscape pages.
