This document describes PNG (Portable Network Graphics), an extensible file format for the lossless, portable,
well-compressed storage of static and animated raster images. PNG provides a patent-free replacement for GIF and can also
replace many common uses of TIFF. Indexed-color, greyscale, and truecolor images are supported, plus an optional alpha
channel. Sample depths range from 1 to 16 bits.
PNGv4/v5 may improve compression but it won’t be backwards compatible. It’ll get stuck in the same kind of limbo JPEG-XL is. Until that gets resolved, we’ll have to stick with AVIF/HEIFF/WebP.
I don’t really see the need for advanced compression in lossless files. You generally don’t download those in bulk without looking at lower quality previews anyway. Would be nice if the real file supports the same colour space the preview file does anyway. I’ll appreciate it when it lands, but I don’t think I’ll spend the hours converting my photo library to save maybe half a gigabyte of space.
JPEG-XL is only really in limbo because Google chose to kill it in Chrome in favor of AVIF. Had that not happened, there would have been far more demand for it to be properly implemented everywhere. Sucks, but you’re right that we’ll have to stick with AVIF/HEIG/WebP.

And ain’t that the entire problem with 99.9% of the web using chromium…
