I have a mini benchmark of lossless PNG compressors, in case anyone finds it useful. https://www.olegkikin.com/png_optimizers/ https://www.olegkikin.com/png_op

  It would be really cool to get something like this that is run against all formats and their specific optimizers. I'd like to see how MozJPEG stands up against the best PNG optimizers or how everything compares to webp (which in my experience is the smallest)

    It's hard to objectively compare lossy encoders. Yes, there are various metrics, but you will get very different results depending on which metric is chosen.

  Here's another older one with sample of 12000 random images off the web http://www.phpied.com/give-png-a-chance/ http://www.phpied.com/give-png-a-chance/

  Thank you for keeping it. Slightly improved your current best using optimage: 1_pingo.png - 8484 --> 8454 2_pingo.png - 18540 --> 18483 4_zopfli.png - 91846 --> 91838 https://imgur.com/a/opWft https://imgur.com/a/opWft
