Kind of a tangent, but while the png format uses lossless compression, you do not know that the .png you have in front of you is lossless from the filename; image softwares can and do support preprocessing an image with lossy algorithms to improve the file size.
This is sort of unlike flac for audio – it is technically also possible, but hardly anyone would do it, since the only reason to use flac is for lossless compression.
I get the impression that .png is used alongside .jpg as a general image format, although i don’t really know.
You also don’t know if your .png file has an alpha channel or not – might have been made without one.
It’s not an improvement over PNG.
No one uses it and even if they did, you’d never know since there isn’t a .webl or .webpl to differentiate lossless.
You know a PNG in lossless, you know a jpg is lossy. webp should just be assumed lossy 100% of the time.
