Why are the images on iPhone or in iCloud show image size over 2X as compared to the downloaded images?
I have been using PhotoSync to transfer photos to my PC from my iPhone and I was somewhat concerned when I noticed the image size was less than half than what is on my iPhone. I first thought PhotoSync has compressing the files but looking at the settings it is set to download original size. In the example below, the iphone shows my image size is 6.7MB which is also what is shows when I look at the same photo in iCloud. When I use iCloud or PhotoSync to download the image to my PC, the image size is only 2.99MB. When I look in the iCloud Photos folder synchronized to my windows PC, it also shows an image size of 2.99 MB. Why would this be? The conspiracy theorist in me is that Apple is artificially inflating the size of the photos to consume more iphone storage / iCloud space but there has to be a better explanation. Thoughts?
