Hello
I imported a number of photos from my iPhone 4S to PC through USB cable (almost always) in 2015. At that time I forgot to delete the copy on my iPhone. Yesterday, I imported the same set of photos again to PC through USB cable and this time, I check the size of the images, for those imported in 2015 and now 2017 on my PC. I found that they are all with the almost same size but NOT the same. For example, 2,642,252 bytes and 2,655,370 bytes for the same photos, even after their EXIF were completely removed, the same photo couldn't achieve the same size
Why does this happen? Does the one with slightly smaller size come with lower image quality?
