Squoosh does not use best-in-class codecs [1]. Lossless PNG compression is 5-15% worse on average and lossy PNG compression (color quantization) is limited to PNG-8, which is not enough to maintain image quality. Lossy JPEG compression is only tuned for 4:2:0 chroma subsampling and causes blurring of fine details because trellis quantization is guided simply by the variance in DCT domain.

It's marketing hyperbole, no one really believes it's the absolute best-in-class. The idea of this open source app from Google is to demonstrate a real world use case of porting legacy native code to the web via webassembly

  Exactly and if you need to quickly optimise some background JPEG to save 400Kb , because the designers / developers haven't optimised the flipping images.

  The quality of a codec is easy to measure, and saying that it measures higher than others is not a hyperbole, but a lie. If you take something that's hard to compare, like developer effectiveness, and say he's the best, then it can be called a hyperbole.

I tested it yesterday, and it seems good enough for me. I'd love to use ImageOptim, but I don't have a Mac, and the web plans are too expensive for optimizing maybe two images every three months.

  Try hackintosh it’s great fun if you like OS X

    If you are a masochist, it’s for sure fun. If not, you really won’t like your installation constantly breaking, not being updatable without great trouble and just not being able to be relied upon in general. Not to mention this is illegal.

      eh... illegal, depends on how you got access to MacOS and on your jurisdiction as well as the reasons for doing it. (Research, for instance.) The other points, I agree with 100%.

      I strongly agree on the former, but wasn't illegal only for criminal law? This would be a licence violation with a fine from civil law, no? I'm not is lawyer though, just surprised about the illegal term in this context

        No, "illegal" is "unlawful" and also covers civil law (or any other body of law). The word you're looking for is "criminal".

      It's a TOS violation, and Apple does make things like imessage a pain, but it's not illegal, provided you got the installer from the mac store and not off the internet.

  You could try the online version of Imageoptim (with not as many options) here: https://imageoptim.com/online https://imageoptim.com/online

    Thank you! Is that even linked from somewhere on the ImageOptim site?
