please allow the game to use avif its much more efficient and smaller.
my mod folder is taking up 4gb of png files this can be reduced by 70% with avif.
there are batch apps to convert all png to avif lossless

Doesn’t make much sense, because it needs to be unpacked when loading, which takes up some more time. Then it seems to be a non-loseless kind of compression which is bad , because in Factorio every pixel counts. And unpacked into memory the images have the same size, because that’s what’s done to make the graphics fast... I would mean the prize for 3 GB on your hard disk is much cheaper, than these disadvantages.

4gb of disk space is a problem? it is not 1998

As mentioned in the OP, AVIF does have a lossless mode. I've no clue about unpacking time/memory so your other points probably still stand though.

Avif sucks hard for lossless compression.

If that’s all true, then lossless WebP seems to perform better. But for these 10-20% - I don’t know if that makes sense.

generally the tradeoff is in the size vs performance. better compression is going to be slower both in decompression and compression. so, you'll sacrifice load times.

overall a bad idea for no gains
