After 20 years, PNG is back with renewed vigor! A new PNG spec was just released.

Now the noob is using wepb for a bunch of rasterised vector graphics with 4 or 5 flat colors, and he’s wasting more disk space than before.

I just tested with this image:

Default GIMP WebP export settings (90% quality): 88.8 kB

Lossless WebP mode: 85.6 kB

Default GIMP PNG export settings (compression level 9): 189.8 kB

So I don't trust this claim unless you have some evidence.

    It's ironic how WebP lossless mode is actually better at compressing the image than the lossy mode.

    I bet most people would use the default thinking that they are making a compromise and that increasing the quality would make the compression worse. They wouldn't know unless they tested making the images themselves, because it's not easy for users to differentiate lossy webp from lossless webp.

    This imho is why lossless should be in its own format, instead of trying to make a single container format do everything like WebP was trying. A new compression level for PNG would be most welcome.
