Photos file size reduced when synced to iPhone
I used iTunes to copy a folder of photos from my iMac to my iPhone 13.
When I view the file size on the iPhone of any photo it is drastically smaller than the original photo on the Photos app on the iMac. For example, file size on iMac 2.4Mb, file size of photo file after copying to the iPhone is 649kb.
Why is that?
I do not use iCloud.
Thanks, Peter
