It looks like the the creator (Jon Sneyers) has since (2019) made another image format more focused on the lossy compression, FUIF[0], which itself has been subsumed by the JPEG XL format[1]. I hope the "JPEG" branding doesn't make folks think that JPEG XL isn't also a lossless format!

JXL is an interesting standard. Integrates a recompressor that shaves ~20% off .jpgs without further loss(!), FUIF for essentially-lossless images in a progressive/interlaced mode like this, a separate lossless format, and a new lossy format with variable-sized DCTs and a bunch of other new tools (other transforms for DCT-unfriendly content, postfilter for DCT artifacts, new colorspace, chroma-from-luma...). It's intended to be royalty-free.

I'm not sure if putting it all under one standard will make it hard to adopt, and/or if AVIF (based on AV1) will just become the new open advanced image format first. Interesting to see in any case.

I think the progressive loading feature of FLIF/FUIF/JXL would be really interesting for WebGL. WebGL games already have asynchronous resource loading and incremental image decoding/texture upload just by virtue of using the available APIs. One could get a pseudo texture streaming effect by default (although no unloading of textures...)

[twotwotwo]

The fancy new lossy mode has some incremental loading too; could be interesting for both.

I think someone forgot to multiply by 100. (too bad, I mean 172x compression would be even more amazing!)

JPEG XL is either lossy compression for large pictures, or something named by people who suck at branding.

[andrewzah]

Made by the same folks who brought you JPEG 2000. /s

[pmarreck]

I was a fan/proponent of that! Whatever happened to wavelet compression?

[loeg]

Patents.

[ksec]

Most of them had expired. Wavelet is something that looks good in theory but in practice couldn't beat the millions man hours work put into standard DCT.

And AVIF was that weird video format before mp4 became common everywere, right? /s

Last time I heard they were teaming with Google Pik for the JPEG XL format. Don't know where they are at.

Still there. Collaboration is ongoing.
