First of all congrats, you are about to know 1337 h4x0r knowledge that 99% of humanity will never know about: WebP can compress PNG images with 0 loss in quality. It's not limited to lossy slop and this is important for video screenshots because video codecs are not (usually) lossless. PNG related has been extracted from a madVR render using very high quality NGU chroma upscaling, this is as good as it gets for video screenshots.

Lossless Webp: https://files.catbox.moe/4bi9sh.webp
40% smaller than PNG, from about 800 to 500 KB

Lossless JXL: https://files.catbox.moe/xb2c1v.jxl
50% smaller than PNG, from about 800 to 400 KB

JXL wins here in compression efficiency but not in everything else. Lossless WebP is:
>faster to decode
>supported by a gorrillion image viewers/editors
>support by nearly 100% of web browsers
>more battle tested (ie most of the serious security vulnerabilities have been discovered)
>native support on most modern OSs

>"bbb-bhut WebP make me ANGERY! Death to Webp!"
Not my problem.

To prove my point further, a 100% lossly slop JPG is often BIGGER than a lossless WebP image.

Can you test with anime screenshots instead?
>>
>>107726347
You got it but a movie screenshot is more of a "balanced" test image since it's not like 12 colors and a bunch of black lines.
>>
>>107726394
It's not balanced it's low-frequency. Anime contains both low- and high-frequency information. That's balanced. And that's why everyone tests with anime screenshots except Google shills.

I want qoi to become the next standard. Fuck all these complicated formats that take a book to describe and a phd to write a codec for. Qoi's super fast and compresses well with high school level complexity, why even bother with other formats anymore for normal images?
>>
>>107726467
QOI fails to meet any requirement of anyone who would proactively choose their image codec.

Don't know what to tell you man, modern anime is honestly perfect for shilling lossless Webp. Nothing is drawn by hand anymore like it was before the year 2000. Modern anime is like 90% close to flash animations with some color gradients sprinkled here and there to keep it from looking too flat. Case in point: this is from "after the rain", again using NGU very high quality chroma upscaling from a 10-bit 1Mbps HEVC rip. Tons of high frequency detail already destroyed by an anemic 1Mbps HEVC rip but I'm not going to wait 10 hours for a download lol.

Lossless Webp: https://files.catbox.moe/272sii.webp
50% smaller than PNG, from about 1.3MB to 700 KB

Lossless JXL: https://files.catbox.moe/315etc.jxl

This time the lossy slop 100% quality JPG is like twice as big as the fucking lossless WebP. I guess JPG doesn't like anime screenshots with 12 colors and a bunch of black lines?
>>
>>107726696
>>107726717
They look the same!
>>
>>107726877
Yeah, that's what a 100% quality JPG should do. However it's quality has now suffered compared to the lossless WebP.

Hey did I mention that the file size of the 100% quality JPG is greater than the filesize of the lossless WebP????
>>
>>107726315
this is simply not true
>>
>>107726922
Sorry man, apparently only 1% of humans can understand any of this. Go back to whatever mundane thing you were doing, the smart adults are talking here.
>>
>>107726315
Doesn't matter. Both storage and internet speed are virtually unlimited these days. Quarter of a century too late.

I don't care that you're a good goy paying $100/month for mobile internet. I will never pay more than $10/month and I will do everything in my power to keep that as usable as possible.

>>107726333

varies on program used what 100% jpeg is 4:4:4 100% filesize is insane compared to normal adobe or camera manufacturer software that has somewhat smaller filesize and maybe 4:2:2
>>
>>107727010
GIMP, use by billions I believe. Not everyone wants to kiss adobe stinky feet to resize/crop/color grade an image.
>>
>>107727003
Good for you. I don't use the internet all that much anymore, and with the honorable exception of this shithole, hardly any of what I do involves multimedia. Literally useless on my end.
>>
>>107727025
GIMP is not used by billions of people.
