PNG is good only because it's widely supported. It only has 8bit per channel, no support for arbitrary channels, has subpar reading and writing performance. For lossless purposes I suggest TIFF, for packing data OpenEXR is best and JPEG-XL is very promising but has limited support right now
Here is an article (centered on a film use case) https://www.provideocoalition.com/fight-of-the-file-formats-pngs-or-exrs/
Compatibility is really important, which is what this post is all about. In a discussion about automatic conversion, PNG should be on the table.
Agreed, I'm only here to inform
What are you guys even doing with your images?
I use png or jpg depending on what I want and that's about it.
Yea me too... given the state of support for modern formats
