@hj @jonossaseuraava @takao So if some clueless user sends a 30MB png photo it gets just png optimized? If they are sending a flow-chart jpeg that is huge it gets downsized to non-readable size? Just saying not all content is simple "photos" where resolution or quality doesn't matter. Not to mention good luck on having any sort of "art showcasing" or portfolio sharing if the server insists on shittifying the quality (no, full-hd jpegs don't cut it most of the time).

Server transcoding actively fights against the user's wishes. It would be more usable to enforce sane upload limits and leave the decision on how to achieve those to the user. Also that gets rid of "double lossy processing".
