tools
dithermark – lets you dither images. my favorite settings are floyd-steinberg for the algorithm and k-means for “optimize palette” (at the bottom). you should play around with color comparison though, usually oklab is the best but there’s many cases in which it’s different
wigglypaint – paint tool but with line boil kind of effect. produces gifs
squoosh.app – go-to image compressor.
