How do I download high quality JPEGS from iCloud photos
I have all my photos backed up on iCloud photos (with the optimise storage setting on).
When I choose a photo from my phone and email it to myself, I have the option of choosing the file sizes (small, medium large, actual size) - if I choose the largest actual size, I get the full resolution JPG (e.g. 12 MP for photos taken with my most recent iPhone).
However, when I download a picture in JPEG from the iCloud browser site (i.e. on my windows PC/browser) - it is usually around a third of the size and around 4 MP. How can I get the same full resolution JPG from iCloud (like the one I get when I email a photo to myself from my phone)? I know I can download the full size HEIC file but wondering if it is possible to get the full resolution JPG from iCloud since I can get that by manually emailing myself on the phone.
thanks all in advance
