If you wanted better compression, it's called Lossless WEBP. Lossless WEBP is such a nice codec. Compared with Lossless JXL, it decompresses many times more quickly, and while JXL usually produces a smaller file, it doesn't always.

Lossless AVIF is not competitive.

However, lossless WEBP does not support indexed color images. If you need palettes, you're stuck with PNG for now.

Webp is a joke. The reference encoder can't even get color spaces right.
