Cloudflare Mirage
Cloudflare Mirage accelerates image loading on your domain.
It does this by:
- Automatically resizing images using JavaScript (by analyzing visitor connection and device type).
- Virtualizing images, so visitors on poor connections get a smaller version at a lower resolution until they can access a higher bandwidth connection.
- Streamlining image requests, so visitors can see optimized images immediately.
- Acting as a lazy loader, turning all images into load on demand.

EXAMPLE.COM/?forcepreloadonly
