HALIC is by far the best lossless codec in terms of speed/compression ratio. If lossy mode were similarly available, we might not be discussing all these issues. I think he stopped developing HALIC for a long time due to lack of interest.
Its developer is also developing HALAC (High Availability Lossless Audio Compression). He recently released the source code for the first version of HALAC. And I don't think anyone cared.
AVIF/AV1 is a codec that encodes both lossy and lossless files very slowly. JXL is significantly faster than AVIF. But AVIF provides better image quality than JXL even at lower settings. However, AV2 will require much more power and system resources for a small bandwidth gain.
If you are really going to do something new, I recommend that you proceed through a work that is very good at this. For example, HALIC(High Availability Lossless Image Compression). It is both extremely fast and has a very good compression ratio, and memory usage is very very low. There is also very strong Multithread support already. I think something like this would be great for the new PNG. Of course, we don't know what the author of HALIC thinks about this.
Solutions such as OptiPNG and Pngcrush require extra processing power on top of the already slow PNG. But in most cases they are still behind.
Yes, I also think that HALIC should be destroyed ;)
Champion! I wish you hadn't commented so ignorantly. Please also try to look at the processing speeds! Or you can also try not to comment at all...
HALIC does almost the same degree of compression tens of times faster. And interestingly, it consumes almost no memory at all. Unfortunately, this is the case.
QOI is just a simple filter. It cannot do full compression. In fact, in certain cases it can increase the size instead of compressing. It is unnecessarily overrated, of course, mostly because it is open source. The rest is irrelevant. There are another codecs that is as fast as QOI (or even faster and multi-core) but with a much higher compression ratio.

But because it's closed source, it definitely didn't get the attention and respect it should have gotten. And that's why I think it stopped developing.

In lossy mode I think there is no difference between AVIF, HEIC or JXL. AVIF is even a little bit ahead.
For lossless mode, JXL's fast modes (-e1 and -e2) are fast. But their compression ratio is terrible. The higher levels are not usable in a camera in terms of speed. Of course, my favorite and many people's favorite in this regard is HALIC (High Availability Lossless Image Compression). It is a speed/compression monster. The problem is that for now it is closed source and there is no Google or similar company behind it.
Hakan; Ignore the open source stuff for now. I speak as someone from within the industry. You may not listen to me and be upset later. If those who say this had done even half the work you did, be sure they wouldn't be talking like this.
It seems that there is a serious effort. And your work clearly crushes other codecs. This will cause serious discomfort in some circles. I don't know much about HALIC, but it is said that it is also a very serious work.
There's no point in rushing for open source. First of all, improve your work as much as you can. If serious offers come later, you can evaluate them. Don't give up control.
