One synced library across devices
Apple says that deleting a photo or video on one device removes it from other devices where you are signed in with the same Apple Account and iCloud Photos is turned on. That includes changes made from Photos on iCloud.com.
Recently Deleted is synchronized too
Deleted items normally move to Recently Deleted for 30 days. They can be recovered during that window or permanently deleted sooner. If you permanently remove an item there, it cannot be recovered through Photos.
Deleting a photo is different from erasing a device
Apple makes an important distinction for people selling or trading in an iPhone. Manually deleting a synced photo changes iCloud and connected libraries. Using Erase All Content and Settings removes personal information from the physical device without deleting the content stored in iCloud.
Back up and transfer first. Review individual media only if you want the library itself to change, then erase the old device using Apple’s documented workflow.
Downloaded and optimized media
An iPhone may store an optimized local version while the full-resolution original remains in iCloud. That does not make deletion local-only. The Photos library state is synchronized. Likewise, a privacy scanner may need Photos to download an iCloud-only item before local classification, but it still operates on an item managed by Apple Photos.
Shared libraries require attention
In an iCloud Shared Photo Library, participants can remove media, and the change affects other participants. Apple notes that only the person who originally added an item can permanently delete or recover it from Recently Deleted before the 30-day window ends.
A safer cleanup checklist
- Confirm whether iCloud Photos is enabled.
- Verify backups outside the synced library if the items matter.
- Review every selected photo or video.
- Check another connected device after deletion if synchronization status is uncertain.
- Open Recently Deleted before considering the cleanup complete.
