Add PDF Watermark
Add text or image watermarks to PDF pages for branding or document control.
Add text or logo watermarks in your browser. This tool adds marks only and does not remove existing watermarks.
Input limit: 35 MB. Processing runs locally in your browser.
What Each Setting Does
- Pages: apply watermark to all pages or only the first page.
- Position: anchor point for single watermark placement; disabled when tiling is on.
- Tiling: repeats the mark across the page so it is harder to crop out.
- Opacity: lower values are subtler; higher values are more visible over content.
- Rotation: angle of watermark; 45deg is the typical diagonal stamp style.
- Font Size (text mode): controls text watermark footprint.
- Image Scale (image mode): controls logo width relative to page width.
