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.
