Please Allow Posting Images In Formats Without Active Lossy Compression

This is from the old file before the upgrade, All that's changed is I added webp a few years ago to the end. That file was used for at least 8-10 years before webp was added.

If you're making them undergo lossy compression anyway (which seems to be the case if I interpret you correctly) there's no need.

In practice if I needed to upload a PNG file (after doing that directly became impossible) I used whatever random online converter I googled up that day (that had a lossless setting) to convert it to WEBP, then uploaded that. I suspect that most WEBP files I uploaded before this year were those; it's a pretty rare format otherwise.
I'm not sure if those would now be lossily-compressed too even if they're under 300 kilobytes. If yes... I guess Imgur or whoever are my friend now.

2017 sounds plausible. I guess it doesn't feel that long ago...


The error message I got must have been older than that, because it only listed JPG, JPEG, and GIF.

I guess it's just awful memories of trying to do geometrical diagrams in MS Paint and crying at how the JPEG files come out with all those ugly squares...

Also for the simple PNG files often the JPEG will be larger than the original even if lossy. Not sure if that's still true for WEBP.
