The Photos app identifies duplicate photos and videos in your photo library in the Duplicates album. You can merge duplicate photos and videos to save space and clean up your library.
- Tap Albums, then tap Duplicates below Utilities.
Duplicate photos and videos appear next to each other. - Tap Merge to combine the duplicates, then tap Merge [number] Items.
Merging combines the highest quality version and all of the relevant data across the duplicates, and keeps that one in your library. The remaining duplicates are moved to the Recently Deleted album.
If you don’t have any duplicate photos or videos in your library, the Duplicates album doesn’t appear.
(This how-to is based on my experiences and info on Apple’s support pages.)
