It seems image formats have ossified. Nobody cares if the images are 50% smaller because storage and network are cheap enough not to deal with the hassle of using a non-standard image format.
Do you really think people are working on improved image compression just for fun, and not because "somebody actually cares"?
Also, it is not just about compression, it is also about functionality. HDR displays are a thing, images with alpha transparency are also a thing. There just is no way to properly do HDR and alpha without "dealing with the hassle of using a non-standard image format", unless you think 16-bit PNGs are a good idea for the web.
Its then (usually, but it is optional) encrypted to make sure that its hard to copy. The keys are sent directly to each projector to allow time limited, and or other limited use.
The reason why its used is because it optimized for quality, rather than size. It also allows custom colour spaces and other tweaks to maintain/enforce colour correctness/image quality.
Inovation ? Will it make life easier for people ? No. You still need to update. Will the page load faster ? No page still has 30 Mb at 50 kbps. Lossless ? Same as PNG. Lossy - same as JPG. So what is the inovation ? That with 20 threads on an Epyc is very fast ? How about my 1ghz phone with 4 cores ?
> Lossless ? Same as PNG. Lossy - same as JPG.
This is incorrect, JPEG XL is smaller.
Also why do you put spaces before your question marks? It makes your post look rushed.
