I like PNG's lossless compression. I feel like PNG was a really bad format back when hard drives were 100GB, but now storage is so cheap. I didn't know JPEP-XL had a lossless mode. Other than that format, I don't know of any other formats that offer lossless compression other than bitmap and TIF. You can't really use TIFs in many contexts and bitmaps have no compression at all.

RAW is the correct format for uncompressed images, and you can shoot RAW on iphone: https://support.apple.com/en-us/119916

You talk about "hard drive" space even though phones don't have hard drives (more to the point, even if you transfer photos to your desktop they will start on your phone and take up space). The iPhone 15 base model comes with 128GB storage. Uncompressed images take up huge amounts of space and that still affects network transfer times, phone storage, cloud storage, etc.

Anyway you can shoot RAW on your phone right now, which is what you are looking for. Still, it is a niche application because of the storage required.

I can't imagine a PNG actually having a good compression ratio for photographic data. Better at that point to just shoot RAW.

Why not?

Storage isn't cheap, check the iPhone storage upgrade prices

And apps have grown in size, and video/photo size has grown

"Storage isn't cheap" "check the [Apple product] upgrade prices"

Under this logic, RAM is still $100 / 8GB, a factor of ~4x greater than non-Apple prices. A similar coefficient is true for their SSD storage pricing.

WebP also has a lossless variant, and it compresses much better than PNG.
