Responsive Asset Delivery
Serve the right image format and size for each viewport automatically.
When to Use Responsive Asset Delivery
Serving desktop-sized images to mobile devices wastes bandwidth and kills performance. Responsive asset delivery ensures every visitor gets images optimized for their specific screen-faster loads, better Core Web Vitals, higher conversions.
- ✓ Your mobile pages load slower than desktop
- ✓ Core Web Vitals scores need improvement
- ✓ You have image-heavy landing pages
- ✓ Mobile bounce rates are high due to slow loading
