Using AVIF images in WordPress
AVIF images work like any other image format in WordPress, with a few important notes:
AVIF in WordPress depends on support in your web server’s image processing library (WordPress has built-in support for both Imagick and LibGD for image processing). You can check for AVIF support in wp-admin by visiting Tools -> Site Health, clicking the “Info” tab and expanding the “Media Handling” section, then finally looking for “AVIF” in the list of supported formats.
If your audience includes a significant number of users on an unsupported browser, either avoid using AVIF images, or enqueue a browser polyfill.
