This project uses HTMLMinifier, optipng, and zopfli to create a custom production Elm build pipeline. You can see how I make use of these tools in this build script. Here are the results in case you're interested. I used the same ideas from this project to build and deploy dwayne/elm-conduit, which you can learn more about in my article Yet Another Tour of an Open-Source Elm SPA. - Source: dev.to / about 1 month ago

Did you compare to PNG crush and optipng? Those are what I used to use because they're easily installable Linux/brew packages. Source: over 1 year ago

Assuming your frames are PNG files, you could use a lossless optimizer like optipng to try if their size can be reduced. I prefer oxipng, which is faster and multithreaded, and seems to have more active development. Source: over 2 years ago

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. Other notable Google projects using Swiss German: https://github.com/google/gipfeli perceptual JPEG encoder Guetzli = Cookie... - Source: Hacker News / 2 months ago

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 / almost 2 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 2 years ago
