@darekkay For encoding, you'll get much better results if you use avifenc (part of the libavif repo) to encode avifs and cwebp to encode webp images. avifenc lets you use all the features of the libaom, svt-av1, and rav1e encoders; you can also tune for perceptual quality metrics and balance encoding speed against target sizes.

Both can accept PNG and JPG images as input.

@Seirdy I think I missed the Windows support the first time I looked into libavif (or I couldn't make it work for some reason). I'll have another look, thanks!
