Author here! I don’t think many people have researched or optimized on this, but I also work on https://squoosh.app https://squoosh.app, and from that experience I know that dithering makes compression _worse_ most of the time (unless you use PNG and use a super small palette of colors). Interesting idea tho!

- shadowfaxRodeo 6y agoHi Surma! fantastic article. You can save a lot of data switching to a lossless format as you said, and especially when using ordered dithering. Even if the color palette is quite large. Error diffusion causes problems for certain color palettes, but usually results in a smaller image size. I've made a tool for doing this: https://doodad.dev/dither-me-this https://doodad.dev/dither-me-this, you can easily half the size of a jpeg by dithering it and exporting it as a png.
