i still convert stuff to JPEG-XL just to see how well it does even though the format is dead

screenshot of pleroma
80K PNG (direct from flameshot)
32K PNG (pngquant)
152K JPEG (mozjpeg, q100)
24K WEBP (graphicsmagic, default)
64K (jxl, lossless)
36K (jxl, error limit 1 [perceptive lossless])

of note: the webp fucks the colors. letters look smaller, profile pics get blurred.
