## AVIF/WebP support detection
imgproxy can use the `Accept` HTTP header to detect if the browser supports AVIF or WebP and use it as the default format. This feature is disabled by default and can be enabled by the following options:

**📝Note:** imgproxy prefers AVIF over WebP. This means that if both AVIF and WebP detection/enforcement are enabled and the browser supports both of them, AVIF will be used.
