Currently, only image/png and image/jpeg are supported for transformation.

Download, extract and place the file(s) in a directory called AVIF in your extensions/ folder.
Add the following code at the bottom of your LocalSettings.php file:
```
wfLoadExtension( 'AVIF' );
```
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
