Once Bunny Optimizer is enabled, it automatically optimizes your static assets without any code changes. This guide covers the available configuration options.

​
WebP Image Compression

Automatically converts images to WebP format for supported browsers, reducing file sizes by up to 80% while maintaining visual quality. How it works:
  • Original URLs remain unchanged (e.g., image.jpg)
  • WebP is served transparently when supported
  • Verify by checking the content-type header: image/webp
  • Unsupported browsers receive the original format

​
Smart Image Optimization

Serves appropriately sized images based on device type (desktop vs mobile). Configuration:
  • Maximum desktop image width: Images larger than this are automatically downsized
  • Maximum mobile image width: Separate sizing for mobile devices
  • Desktop image quality: 0-100% (recommended: 85-90%)
  • Mobile image quality: 0-100% (recommended: 75-85%)
Lower quality settings on mobile save bandwidth without noticeable quality loss on smaller screens.

​
CSS & JavaScript Minification

Removes whitespace, comments, and unnecessary characters from CSS and JavaScript files.
  • Smaller file sizes
  • Faster download times
  • Identical functionality
Toggle these independently in your Optimizer settings.
