High Compression Quality
Guetzli is designed to produce JPEG images that are visually indistinguishable from the originals, achieving high compression quality without introducing noticeable artifacts.
Smaller File Sizes
Compared to standard JPEG encoders, Guetzli often results in smaller file sizes, which can be highly beneficial for web performance by reducing load times.
Open Source
Being open source and available on GitHub, developers and researchers can contribute to its development or customize it for their specific needs.
Improved Visual Perception
Guetzli uses a perceptual approach to compression, focusing on elements of an image that are more noticeable to human eyes, which translates to better visual quality in compressed images.
We have collected here some useful links to help you find out if Guetzli is good.
Check the traffic stats of Guetzli on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Guetzli on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Guetzli's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Guetzli on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

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 Zรผrich.

A JPEG encoder developed by Jyrki Alakujala, Robert Obryk, and Zoltรกn 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 3 years 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: almost 4 years ago
Guetzli. Looks like development has stalled? Perhaps for just that reason. https://github.com/google/guetzli. - Source: Hacker News / almost 4 years 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 / almost 4 years ago
If you're going for full re-encoding, it might help to decode the current JPEG with https://github.com/google/knusperli ... But if you re-JPEG that you might have second-order artifacts. Give it a try. Then compress with https://github.com/google/guetzli. Source: almost 4 years ago
Turns out there is a project which does that: https://github.com/google/guetzli. - Source: Hacker News / about 4 years ago
You know. I was actually quite annoyed ( to say the least ) with the post. For one the post is lacking a date, and you have to search yourself it was published in April 2017. And without a date the article is completely lacking context because Guetzli [1] hasn't been worked on for 5 years. And as [2] mentioned its work and derivative was ultimately merged into JPEG XL, which is a very decent image format. ( People... - Source: Hacker News / over 4 years ago
Now for the jpeg, guetzli looks interesting, but it is a lossy compression. You compress jpeg, which already has some artefacts, for the second time. There will be more artefacts. Source: about 5 years ago
