# AVIF Optimization

**AVIF Optimization** enables Medianova CDN to dynamically convert eligible JPG, JPEG, and PNG images to AVIF and deliver them to supported browsers. AVIF reduces image file sizes while maintaining visual quality.

Conversion occurs during content delivery, so the original images at the origin remain unchanged.

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 Optimization

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

## AVIF behavior

When AVIF Optimization is enabled:

* Eligible JPG, JPEG, and PNG images can be converted to AVIF.
* AVIF conversion occurs dynamically during content delivery.
* Browsers that support AVIF receive the converted version.
* Browsers without AVIF support receive the original image format.
* The first generated AVIF version is cached for subsequent matching requests.
* Original images at the origin remain unchanged.
* No additional AVIF images need to be stored at the origin.
* Existing image URLs do not require modification.

## Benefits

* Reduces image file sizes by up to 90% compared to the original image.
* Reduces bandwidth consumption.
* Maintains visual quality at smaller file sizes.
* Requires no additional image variants at the origin.

## 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.
