The short answer
Open Photos › Albums › Utilities › Duplicates and tap Merge, then empty Recently Deleted. That clears exact duplicates only. For bursts, retakes and screenshots — where most of your storage is actually going — use a cleaner that groups near-duplicates and lets you swipe through them.
Method 01
Use the built-in Duplicates album (iOS 16+)
Apple's Photos app detects exact and very close duplicates automatically. It is free, but it only catches true duplicates — not burst shots, retakes or blurry near-copies.
- 1Open the Photos app and tap Albums.
- 2Scroll to Utilities and tap Duplicates. If you don't see it, your library is still being scanned — plug in, lock the phone and wait.
- 3Tap Merge next to a pair, or Select then Merge to clear several at once.
- 4Merging keeps the highest quality version and moves the rest to Recently Deleted.
- 5Open Albums › Recently Deleted and tap Delete All to actually reclaim the storage.
Storage only frees up after you empty Recently Deleted — otherwise the files sit there for 30 days.
Method 02
Clean near-duplicates manually
Most wasted space isn't exact duplicates — it's the eleven almost-identical shots you took to get one good one. Photos won't group these for you.
- 1In Photos, open a Day or Month view to see bursts side by side.
- 2Tap Select, then drag across a row of similar shots to mark them quickly.
- 3Keep the sharpest frame, delete the rest.
- 4Repeat for Screenshots (Albums › Media Types › Screenshots) — usually the single biggest win.
- 5Empty Recently Deleted when you're done.
Effective but slow. Expect an evening or two for a library over 10,000 photos.
Method 03
Use a photo cleaner app (fastest)
A dedicated cleaner groups near-duplicates for you and lets you decide with a swipe instead of a tap-tap-confirm loop. Clean Cut does this fully offline.
- 1Install Clean Cut from the App Store and grant photo access.
- 2It scans on-device, grouping bursts, retakes, screenshots and near-duplicates.
- 3Swipe right to keep, left to bin — Clean Cut suggests the sharpest shot with eyes open in each group.
- 4Everything you bin waits in a review pile. Nothing is deleted until you confirm.
- 5Confirm, then empty Recently Deleted to reclaim the gigabytes.
Nothing is uploaded — the whole cleanup runs on your iPhone, no account needed.

Frequently asked questions
Why doesn't the Duplicates album appear on my iPhone?
It needs iOS 16 or later, and the library scan only runs while your iPhone is locked and charging. Give it a night on the charger and check Albums › Utilities again. If you have no exact duplicates, the album is hidden entirely.
Does deleting duplicates in Photos free up iCloud storage too?
Yes, if iCloud Photos is on. The deletions sync, but only after you empty Recently Deleted — until then the files still count against your plan on every device.
Will I lose the good version if I merge duplicates?
No. Apple's merge keeps the highest resolution copy and preserves the combined metadata, such as favourites and keywords.
What's the difference between duplicates and near-duplicates?
Duplicates are byte-identical or nearly identical files, usually from re-saves and shared imports. Near-duplicates are separate photos of the same moment — bursts and retakes — which Apple's album ignores, and which is where most of your wasted storage actually lives.
Is it safe to use a third-party photo cleaner?
It depends on the app. Prefer one that processes photos on-device, doesn't require an account, and puts a confirmation step between your swipe and the permanent delete. Clean Cut does all three.
Skip the tapping. Swipe instead.
Clean Cut groups every burst, retake and screenshot, suggests the best shot, and never deletes anything without your confirmation.
