Your iPhone finds duplicate photos for you. Open Photos, tap Collections, then Duplicates under Utilities, and tap Merge on each set. Photos keeps one copy with the best quality and data, and moves the others to Recently Deleted, where they stay for 30 days.

Where is the Duplicates album on iPhone?

In the current Photos app, Duplicates is a collection under Utilities:

  1. Open Photos and tap Collections.
  2. Tap Utilities, then tap Duplicates (iPhone User Guide).

Matching photos and videos show up side by side, in sets. If your library has no duplicates, the collection doesn’t appear at all (iPhone User Guide). On iOS 16 the path was different: tap Albums, then Duplicates below Utilities (iPhone User Guide).

How to delete duplicate photos on iPhone

You don’t delete duplicates one at a time. You merge them (Apple Support):

  1. Open Photos, tap Collections, then tap Duplicates under Utilities.
  2. Tap Merge next to a set to combine it.
  3. To merge several sets at once, tap Select, then tap Select on each set, or tap Select All. Then tap Merge.
  4. Tap Merge [number] Items to confirm.

On a big library, I’d merge a few sets one by one first, look at what’s left in your library, and only then use Select All.

What Merge keeps and what happens to the other copies

Merge isn’t a plain delete. Apple says your iPhone “combines the highest image quality and relevant data to keep one photo in your library,” and the other copies move to your Recently Deleted album (Apple Support). The iOS 16 guide described it as keeping “the highest quality version and all of the relevant data across the duplicates” (iPhone User Guide).

Apple doesn’t list what counts as relevant data. If two copies in a set differ in a way you care about, I’d open both before merging that set.

The extra copies stay in Recently Deleted for 30 days “before being permanently removed from your iPhone, iCloud, and other devices associated with your Apple Account.” During that time you can recover them or delete them for good (iPhone User Guide).

Why duplicate photos aren’t showing on iPhone

Apple gives three reasons (Apple Support):

  • Your iPhone is on an iOS version before iOS 16. Duplicate detection started with iOS 16.
  • Your iPhone hasn’t finished indexing. For the album to appear, your iPhone has to index your photo library and find duplicates. Apple says this “requires iPhone to be locked and connected to power.” Depending on background tasks and library size, it “could happen quickly or take up to a few days to complete.”
  • It found no duplicates. If indexing is done and the album still isn’t there, “your iPhone has not identified any duplicates.”

To see whether indexing is still running, open Photos, tap Library and scroll down. While your iPhone is indexing, a status message appears at the bottom (Apple Support). If you see one, I’d leave the iPhone locked on its charger overnight and check again.

Similar photos and bursts are a different job

Apple doesn’t publish how alike two photos have to be to count as duplicates. Its pages only talk about duplicates, not similar shots. So if Photos hasn’t put two pictures in Duplicates, picking between them is up to you.

Bursts have their own tool (iPhone User Guide):

  1. Tap the burst, then tap Burst (number) in the top-left of the screen. Gray dots below the thumbnails mark the photos your iPhone suggests keeping.
  2. Tap the circle in the lower-right corner of each photo you want to save as an individual photo, then tap Done.

To delete a whole burst, tap the burst image in your library, then tap the Delete button. For everything else, a slow, review-first pass works better than a mass delete; I walk through one in a safer way to clean up your photo library.

iCloud Photos: one merge, every device

When you use iCloud Photos and delete a photo or video on one device, it’s deleted on all your other devices signed in with the same Apple Account (Apple Support). Merging sends the extra copies to Recently Deleted like any other delete, so expect them to disappear from your iPad and Mac too. Apple’s advice before deleting: back up the photos and videos you still want.

Where the space comes back depends on which storage you’re watching:

  • iCloud storage. “Items in Recently Deleted don’t count towards your iCloud storage.” One catch: if you’re already over your iCloud storage limit, your device removes deleted photos and videos immediately, and they “won’t be available for recovery” in Recently Deleted (Apple Support).
  • iPhone storage. Deleted items stay in Recently Deleted for 30 days before they’re permanently removed from your iPhone (iPhone User Guide). To get the space back sooner, open Collections, tap Recently Deleted under Utilities, tap View Album and unlock it. Then tap Select, choose items, tap More (…) and Delete, or Delete All. What you delete there can’t be brought back (Apple Support).

If the real goal is a full iPhone, duplicates are rarely the whole story. iPhone storage full? How to free up space fast covers the bigger wins.

Can you undo a merge?

Apple doesn’t describe an undo button for merging. What you can do is bring the extra copies back from Recently Deleted within 30 days (Apple Support):

  1. In Photos, tap Collections, then tap Recently Deleted under Utilities.
  2. Tap View Album, then unlock it with Face ID or Touch ID.
  3. Tap Select, choose the copies you want back, tap More (…), then tap Recover.

They go back to your library, next to the copy Photos kept. In an iCloud Shared Photo Library, only the person who added a photo or video can recover it or delete it permanently from Recently Deleted (Apple Support).

What Mistero can and can’t do here

Mistero doesn’t replace Apple’s Duplicates merge. It can’t combine copies into one best version the way Photos does, and it can’t make the Duplicates album show up sooner. For true duplicates, I’d use Photos first: it’s free and already on your iPhone.

Mistero Cleaner, part of the Mistero VPN app, is for what’s left after that. The App Store listing says it can “Find similar photos, screenshots, and large videos,” lets you “Review items before removing them,” and can “Compress large photos and videos to save storage space” (App Store listing, read Nov 2, 2026). Either way, you still decide what goes. More on the feature at Mistero Cleaner, and on shrinking videos you want to keep in when to compress photos and videos instead of deleting them.

Frequently asked questions

Why is there no Duplicates album on my iPhone?

It needs iOS 16 or later, and it only appears after your iPhone has indexed your library and found duplicates. Indexing runs while the iPhone is locked and charging and can take up to a few days. If it has finished and there's still no album, your iPhone hasn't found any duplicates.

Does merging duplicates delete them from iCloud?

With iCloud Photos on, yes. The extra copies go to Recently Deleted on all your devices, and after 30 days they're removed from your iPhone, iCloud and your other devices. The copy Photos keeps stays in your library.

Is there a free way to delete duplicate photos on iPhone?

Yes. The Photos app has it built in on iOS 16 and later. Open Photos, tap Collections, then Duplicates under Utilities, and tap Merge on each set. You don't need another app for this.

Can I undo a merge?

Apple doesn't describe an undo button, but the extra copies sit in Recently Deleted for 30 days. Open Recently Deleted under Utilities, select them, tap More, then Recover, and they go back to your library.
