Bunny Optimizer can automatically apply watermarks to your images to protect intellectual property, reinforce branding, or mark user-generated content.
Watermarks are applied during the optimization process and cached. There’s no performance penalty after the first request.

Watermark image URL

The publicly accessible URL to your watermark PNG (transparency supported). Best practices:
  • Use PNG format with transparency
  • Design at 2x resolution for sharp display
  • Keep file size under 100KB
  • Test on both light and dark images

Minimum image size

Only images with width OR height greater than this value will be watermarked (in pixels). Example: Setting this to 800px prevents watermarks on small thumbnails while protecting larger downloads.

Position

Choose from a few different placement options:
  • Bottom Right
  • Bottom Left
  • Top Right
  • Top Left
  • Center
  • Center Stretched

Border offset

Distance from the edge as a percentage (0-100%). Example: 5% offset on a bottom-right watermark places it 5% away from both the bottom and right edges.

Combining with Dynamic Images API

Watermarking applies before Dynamic Images transformations, ensuring your watermark appears on all generated variants.
