@davidrevoy It's actually throwing away quality for no good reason, unfortunately. With proper handling we can compress JPEGs to half the size for a given amount of quality (or double the quality for a given size). And WebP improves that ratio by ~25-30%, and AVIF by ~50%. And then better dedup'ing (image fingerprintting) could cut server resources dramatically further. There's also proposals for a HQ (but less convenient) image option, with lower default size.

@davidrevoy What it's doing today is basically cutting the resolution way down, but then saving with a high JPEG quality factor. Except lowering the JPEG quality factor saves a lot more space (for a given quality level) than shrinking images. And it doesn't even force conversion of PNGs, so you can post monstrously large PNG files - but it still ruins their quality.

For starters. It's honestly a mess.

(BTW, your work is lovely :) )

@nafnlaus Ha, that's good to see other format and the ratio quality/storage/bandwith being studied. If there is a waste in quality that could be solved without putting weight (or even better, with lighter footprint), I'm all OK!

@nafnlaus I've been thinking about the issue.

Hot take: sacrifice availability and hotlink big images by default.

Keep LQ side by side and federate *it*.
