FLIF VS Caesium Image Compressor

JXL contains FLIF, one of the most efficient lossless formats. Source: 11 months ago

As for lossless image compression, FLIF is based off of a deriviative of CABAC (used by H264) called MANIAC (which I couldn't find any information for). As mentioned on the website in general it outperforms PNG at around 33% smaller files. Interestingly enough, FLIF is a predecessor to JPEG-XL which is what this post is talking about.

I'm a huge fan of AV1 for video, but for images JPEG-XL is simply the better codec than AVIF. If you've not actually looked closely at a comparison and are just on the side of AVIF in this debate because it's based on AV1 (and maybe you hate HEVC / HEIC), I'd urge you to look closer. Jpeg XL is pretty unrelated to Jpeg, Jpeg 2000 and Jpeg XR and instead a successor of Google Guetzli, FLIF and newer research. Source: over 1 year ago

Legally they had no choice because jpeg xl is based on flif.info and https://github.com/google/pik but the flif has LGPL license which should open source the rest.. However regardless the media group didn't really do much other than write some standard and slap their name on it. Wasn't their work. Source: over 1 year ago

No this is a niche format like FLIF was flif.info which got embedded in jpeg xl along with other image technologies. The tech behind QOI and many other things is great, and hopefully the research goes into usage in the future but it won't get mass adoption. Source: over 1 year ago

I also use Caesium Image Compressor on my ROMs and Themes folder to reduce their size and improve the RG35XX's responsiveness. Source: 12 months ago

If you want further compression you could check out Caesium Image Compressor which is free (and I'm not affiliated with it incidentally, I just like it). Source: about 1 year ago

Try an image compression tool, this one is free and open source: https://saerasoft.com/caesium/. Source: about 1 year ago

Caesium Image Compressor can do the job and it is easy to use. There is also imagemagick which is basically the swiss-knife for image editing, but based on you having looked for websites first, I assume you don't look for a commandline tool (imagemagick is a commandline tool).

I can recommend Caesium , a utility (Windows, MAC version in Alpha test) to remove all EXIF, metadata etc which will reduce your JPG in size quite a lot without using higher JPG-compression (lower quality). Source: almost 3 years ago
