I'm currently working on a post editor for my little BlueSky tools. Allows image uploads as well now.

First surprise: images can't be bigger than 960kb. They currently only support PNG and JPEG.

PNGs always get converted to JPEG and pushed to their CDN. All BlueSky clients fetch from the CDN.

So you always get JPEGs on BlueSky, even if you uploaded and store PNGs in the repo.

I can't even.
