    I'm currently running iOS 11.2.6 on an iPhone X and am having trouble storing .png files via iCloud Photo Sharing.

    If I have a .png image in my camera roll with transparency and choose to upload it to a shared album on iCloud, it will appear and display correctly under the "Shared" tab. However after a minute or so if I return to the same tab and look at the same image, I find that it has been automatically converted to a .jpg file with all transparency lost and image quality degraded. This also happens on Macs and iPads.

    Is there a way to prevent this? I've looked under the iCloud Photo options and can't find anything. (This is separate from the iCloud Photo Library option, which does allow users to change format settings).

    Unfortunately I was wondering the same thing. I think iCloud is quite limited for now, just as the whole cloud infrastructure. Similarly, normal photos are also compressed and when shared via iCloud Photo Sharing, there are not full res or 4K.

    iCloud Photo Sharing downscales all images to 2048x px. Are your PNGs larger than that?

    2100 x 2100, just over that limit.
    However, 512 x 512 PNGs are also being affected.
