Wow, I don't remember reading such a bad article in a very long time. Very disingenuous take.

1) author starts with lossy format at the beginning of the comparison

2) author uses squoosh app for some of his conversions, but not others, even though it supports dithering too - instead uses a random web tool which doesn't care about file size at all

3) not even a mention about image formats supporting limited color palettes

4) no mention of disadvantages of webp and avif (anyone still supports IE 11?)

5) more things like dithered "lossless" webp made from lossy jpg, from the same image you can see that author used much bigger color palette than the one used in Low-tech Magazine images

Funny thing is that aside of browser support modern formats would probably still win even without manipulating the numbers (they are made for this), but I guess the author wanted really convincing victory.

> Very disingenuous take...instead uses a random web tool

You missed that this is a rebuttal to an article that suggests using dithering and to use that specific tool. Hardly "random".

> anyone still supports IE 11?

Fair enough for now, but MS itself is in the process of dropping support for IE 11, so I don't expect others to carry on without them very widely. It will be all retro sites and corporate sites soon (LOL, for completely different reasons -- one wants to visit the past from time-to-time, and the other doesn't know how to escape it)

Ok, not quite random, but still hardly fair. If that's the take, it should be called "Websites should not use images created by this dithering tool" instead.

Usage of IE 11 and other browsers which do not support even webp (old safaris) is higher than usage of screen readers.

Personally I doubt we'll ever experience widespread usage of avif, considering how long it took Apple with webp, we'll probably sooner have jpeg xl.

I think the main premise of the article "Dithering is not Compression". People should use compression algorithms to compress their images. They shouldn't be using "color depth decrease" algorithms to compress their images.
