Convert AVIF to WebP

A halfway house: WebP is bigger than AVIF but has several more years of support behind it, and still keeps transparency and lossless mode. A reasonable target when AVIF is too new for the audience.

What is AVIF?

Built on the AV1 video codec, and the smallest of the widely-supported image formats by a clear margin - frequently half the size of a JPG that looks the same. It handles transparency and HDR. Being new is its only real drawback: plenty of software still won't open one.

What is WebP?

Google's format for the web, and a genuine improvement on both of the formats it replaces: lossy like JPG or lossless like PNG, transparency either way, and usually about 30% smaller. Every current browser reads it. Software that stopped being updated around 2019 often doesn't.
