I wonder how fpng[1] would compare- a lossless speed optimized png compressor. Oh! The author Rich screenshoted[2] a really nice deck[3] that also boasts fpnge[4] and fjxl[5], both of which are even faster, both use AVX2 (or neon for FJXL). Notably fjxl is in the reference libjxl tree. I'm not sure what if any constraints fast mode has, what it takes to use. The article uses cjxl, which does not run the fjxl fast mode, and further, fast mode was added after this article was written[6]. Other notes on jpeg-xl: it has progressive rendering. It has hdr! The deck on FJXL & FPNGE is epic. Thanks Quote Ok Image (QOI) format for setting the fire on this all!!
