libjpeg-turbo VS mozjpeg

This is interesting from the standpoint of how new JVM features can be used to improve performance (what I presume the article's main purpose to have been), but the image processing improvement itself isn't head-turning. Also, we've found that libjpeg-turbo (https://libjpeg-turbo.org/) is ~5x (IIRC, can re-run my JMH benchmark if anyone wants me to) as fast for decoding JPEGs as ImageIO, so we wouldn't even...

For all but the simplest formats (basically BMP), the difficulty of implementing encoding/decoding from scratch is significant - well beyond a beginner's ability, and challenging/time-consuming even for senior developers. So, libraries are used in practice - e.g. Libpng and libjpeg-turbo. Source: over 2 years ago

It would be nice if the author would add mozjpeg[1] to the comparison. At certain sizes, it can produce smaller sizes than WebP, and because it is still a jpeg, it has a much better compatibility story, which the author alluded to.

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

FWIW, Mozilla has been maintaining their own fork for quite a while now[1] AFAIK most Linux Distros have been using libjpeg-turbo as a drop-in replacement for libjpeg, after some drama in ~2010 where libjpeg came under new management, decided to break ABI/API several times over and add incompatible, non-standard format extensions[2].

No. See https://github.com/mozilla/mozjpeg Also, there is a fairly big problem with JPG that the ‘quality’ setting is not calibrated. That is you might look at one image and think it looks fine (which is subjective, depends on what you want to use the image for…) with a quality of 60%, but then you compress a million images at that rate, delete the originals, then... - Source: Hacker News / about 1 year ago
