OpenEXR. Though it probably could use a spec upgrade, in particular add JPEG-XL to the list of compression algorithms. It’s not like OpenEXR’s choices are bad, the lossy ones are just more geared towards fidelity than space savings, kind of the opposite of what you want for the web where saving space is often paramount and fidelity a bonus.
Bonus: Supports multi-channel, so not just RGBA. Not terribly useful for your run off the mill camera, very useful in production where you might want to attach the depth buffer, cryptomatte etc and I guess you could also use it for the output of light field cameras. Oh there’s also multi-view so you can store not just stereo images but also whole all-around captures and stuff. There’s practically nothing pixel-related you can’t do with it though it might require custom tooling.
