Guetzli VS libpng

JPEGLI = A small JPEG The suffix -li is used in Swiss German dialects. It forms a diminutive of the root word, by adding -li to the end of the root word to convey the smallness of the object and to convey a sense of intimacy or endearment. This obviously comes out of Google Zürich.

A JPEG encoder developed by Jyrki Alakujala, Robert Obryk, and Zoltán Szabadka, and released by Google in 2017. Guetzli specializes in high-end image quality where it is claimed to produce significantly smaller files than prior encoders at equivalent quality, albeit at very low speed. It is named after the Swiss German expression for biscuits, in line with the names of other compression technology from Google.... - Source: dev.to / over 1 year ago

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

Guetzli. Looks like development has stalled? Perhaps for just that reason. https://github.com/google/guetzli. - Source: Hacker News / over 1 year ago

I've never had much luck using jpegoptim. In most cases it's only removing the metadata, which isn't much on high-res files. Guetzli is nice, if you don't have too many images to recompress (quite slow): https://github.com/google/guetzli. - Source: Hacker News / over 1 year ago

Is this by the same people or is it a competitor to the PNG development group (http://libpng.org/pub/png/)? The latter's website still heavily says that PNG is a still image only format, and promotes MNG as the animation alternative. Of course, that's not how web browsers have played it out, and it also appears to me that the libpng source code still lacks "APNG" support. This makes me think it's a competing... - Source: Hacker News / 10 months ago
