# AVIF Optimization

**AVIF** enables Medianova CDN to automatically deliver JPG images in the AVIF format to supported browsers. AVIF provides significantly higher compression efficiency than traditional image formats, reducing file sizes while maintaining visual quality.

Because conversion occurs dynamically at the CDN edge, no changes are required on the origin server.

You can manage AVIF using the [Medianova Control Panel](https://cloud.medianova.com) 

Select a CDN resource and navigate to the **Image Optimization** section

### Configure AVIF

Follow the steps below to enable AVIF delivery for supported browsers.

### Behaviour

* AVIF conversion is performed dynamically at the CDN edge.
* Only browsers that support AVIF receive the converted version.
* Browsers without AVIF support automatically receive the original image format.
* No origin-side image processing or additional image storage is required.
* AVIF delivery applies only to eligible JPG images.

### Benefits

* Reduces image file sizes by up to 90% compared to the original JPG.
* Improves page load performance and Core Web Vitals.
* Reduces bandwidth consumption.
* Maintains high visual quality at lower file sizes.
* Requires no changes to existing image URLs.

### FAQ

**Does AVIF replace my original images?**\
No. The original image remains unchanged on the origin. AVIF versions are generated and served dynamically by the CDN.

**What happens if a browser does not support AVIF?**\
The CDN automatically falls back to the original image format.

**Do I need to upload AVIF images to my origin?**\
No. The CDN generates AVIF versions automatically at the edge.

**Is AVIF more efficient than WebP?**\
In most cases, AVIF achieves higher compression efficiency than WebP while maintaining similar visual quality.

**Does enabling AVIF require changes to my application or URLs?**\
No. Existing image URLs continue to work without modification.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://clients.medianova.com/products/performance-cdn/image-optimization-and-webp/avif-optimization.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
