# Optimize images

Images are often the largest assets on a page and the biggest contributor to slow load times. Cloudflare Images resizes and converts images on-the-fly to modern formats like WebP and AVIF, while Polish compresses existing images without visible quality loss.

## Solutions

### Images

Transform, optimize, and deliver images at scale. [Learn more about Images](https://developers.cloudflare.com/images/).

* **Modern formats** \- Automatically serve WebP or AV1 Image File Format (AVIF) to supported browsers, falling back gracefully for others
* **Responsive images** \- Resize and transform images on-the-fly via URL parameters without pre-generating variants

### Polish

Automatic image compression without quality loss. [Learn more about Polish](https://developers.cloudflare.com/images/polish/).

* **Automatic compression** \- Reduce image file sizes through lossless or lossy compression without visible quality loss

### Speed

Improve page load performance with built-in optimizations. [Learn more about Speed](https://developers.cloudflare.com/speed/).

* **Lazy loading** \- Defer loading of off-screen images to improve initial page load and Core Web Vitals
