How much smaller will the AVIF be?

For most images AVIF is dramatically smaller than PNG — often a small fraction of the size — while keeping transparency. The exact saving depends on the image and the quality setting.

Does every browser support AVIF?

All current versions of Chrome, Edge, Firefox and Safari display AVIF. Some older software still does not, so keep the original if you need maximum compatibility.
