Cloudflare Mirage (deprecated)

Cloudflare Mirage was a mobile image optimization feature that reduced bandwidth usage and accelerated image loading on slow mobile connections and HTTP/1.

Mirage worked by:

• Replacing images with low-resolution thumbnails bundled together into one file.
• Acting as a lazy loader, deferring loading of higher-resolution images until they become visible.

Modern web standards and browser capabilities have evolved to provide native support for many of Mirage's features:

• Native lazy loading with the loading="lazy" HTML attribute.
• Responsive images using srcset and <picture> elements.
• HTTP/2 and HTTP/3 providing better performance.
• Improved mobile networks reducing the need for aggressive optimization.

Instead of Mirage, use:

• Polish - Seamlessly optimizes images for all browsers, not only mobile, and keeps images at full resolution.
• Image Resizing - Combined with loading="lazy" and srcset HTML attributes, provides modern responsive image delivery.
• Lazy loading guide - Learn how to implement native lazy loading.
• Responsive images guide - Create images that adapt to different devices.
