Image Optimization
Automatic WebP conversion and image compression.
Automatic WebP Conversion
fast.site automatically converts your images to WebP format for browsers that support it. WebP images are typically 25-50% smaller than equivalent JPEGs, up to 80% on photo-heavy assets, with no visible quality loss.

No changes needed: Your original images stay on your server. We convert and cache WebP versions automatically at the edge.
How It Works
- 1
Browser requests an image
Modern browsers send an Accept header indicating WebP support
- 2
fast.site detects WebP support
We check if the browser can display WebP images
- 3
WebP version is served
The optimized WebP is delivered; older browsers get the original

Animated GIFs and SVGs are served as-is since they don't benefit from WebP conversion.
