AVIF – AV1 based image format

Re:AVIF – AV1 based image format by adamzochowski on Tuesday April 10, 2018 @03:14PM (#16804209)

How is it 95% smaller? FLIF is a lossless compression, and AV1 in lossless mode can't do magic. It can't do 95% better.

https://wyohknott.github.io/image-formats-comparison/report....

FLIF is reported at 59.57% avg space savings

AV1 (2018-02-22) is reported at 66.02% avg space savings

presumably it's 95% smaller because it's not limited to lossless mode?

FLIF is also not limited to lossless mode, http://flif.info/lossy.html

And FLIF's lossy mode is as good as AV1's?

That part I don't know. I haven't seen a comparison between them, but it's compared well at least against BPG, or whatever the h264 based format was. I don't think i've seen a comparison against h265, let along AV1. It'd be interesting to see. Even if they're about as good, I like FLIF's setup better since it enables progressive decoding which could be a big step up for slower connections.
