How Photo Dedup Works

Scans image assets in Apple Photos and looks for likely duplicate and near-duplicate groups.
Suggests a keeper for each group using image quality and metadata signals.
Lets you promote a different keeper, keep multiple photos, skip groups, or mark a full group for deletion.
Requires explicit approval before anything is moved to Recently Deleted.

FAQ

Does Photo Dedup delete photos automatically?

No. Nothing is deleted automatically. You review suggested groups and approve all removals manually.

Where do deleted photos go?

Approved photos are moved to Apple Photos’ Recently Deleted album, not permanently erased immediately.

Can I change the suggested keeper?

Yes. You can promote another photo to keeper or keep multiple photos in the same group.

Does the app work with iCloud Photos?

Yes. If some images are stored in iCloud, the app may need to retrieve them during scanning and review. A solid network connection is recommended.

Does Photo Dedup upload my photos?

No. Photo analysis is performed on-device. Photo Dedup does not upload your photo library to a developer server for duplicate detection.
