OptiPNG vs. PNGcrush vs. Gimp to Reduce PNG Size

Squoosh

The 'indexed' PNG looks quite bad. Using an 8-bit palette doesn't mean using terrible dithering, you can get this image down to 70-80kB with a 80-120 colors palette, and because of the solid surfaces it doesn't need any dithering at all. Try https://squoosh.app, it runs the compressors in-browser with WASM and you can fine tune the parameters live.

Pingo

I've tried a few, the best one was pingo (https://css-ig.net/pingo). Pingo -s9 gives better results than oxipng with Zopfli, while being usually two order of magnitudes faster. It's also faster than "regular" oxipng while being better. I can usually shave of 15%/20% of the size of png files I encounter. One thing I didn't check is that you might pay that in decoding time, I've never seen anybody talking about that though.
