FLIF VS pngquant

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

Image-shrinker is a simple, easy to use open source tool for shrinking images. Under the hood it uses pngquant, mozjpg, SVGO, and gifsicle. You can also install these tools individually if you need to compress some images. I often use pngquantafter exporting PNGs for web projects from Figma or similar tools. I literally run it like this:. - Source: dev.to / 7 months ago

Searching more I found https://pngquant.org/ which I could add to my bulk workflow to make most png's approach the jpeg size. Source: 11 months ago

But this did prompt me to do some searching, and I see https://pngquant.org/ which seems to achieve jpeg like size reduction while maintaining the file as a png. One difference they note is that this method will typically preserve sharp edges better than jpeg (which is probably a strong plus for my type of use case). Source: 11 months ago

Pngquant is also great for shaving filesizes down, but unlike oxipng, it's explicitly lossy. It'll reduce colors and even dither, but it will try to keep an image visually similar. Https://pngquant.org/. Source: about 1 year ago
