I didn't even realize that WebP had an optional lossless compression mode.

[Dwedit]

WebP's lossless compression mode usually beats PNG by a lot, and even decompresses faster. I consider lossless WebP to completely obsolete PNG. Lossless JXL often beats WebP in compression, but loses in decompression time.

Except for indexed color images. PNG beats WebP on those images. Meanwhile JXL beats PNG on indexed color images.
