image/avif

What image/avif is

image/avif is a newer format with excellent compression, wide colour, and transparency — typically smaller than WebP. Serve it with a fallback for older browsers via <picture>.

How it's used

You'll see this as a Content-Type value on requests and responses — for example Content-Type: image/avif. It's the type associated with the .avif file extension. Image types tell the browser how to decode and render a picture.
