Henry Cavill reacts [meta: actual webp => lemmy]

I’m doing some testing to see what the best format / upload site is.

Support for WEBP on lemmy is limited because it automatically converts any webp upload, transcoding it at about a 75% quality setting.
This is true even if it was already compressed, so you end up with a transcode of a transcode, with often poor results.
The only way around this I found, is to upload a losslessly-encoded webp, and let lemmy have at it.
But then, of course, there’s a limitation on how big the original file can be (both in terms of an absolute limit, and how long lemmy will allow for transcoding to happen)

Lossless .webp file, 2.27MB, uploaded to lemmy
Converted by lemmy to compressed .webp, 119KB
