How to Find and Delete Duplicate Photos on iPhone

Duplicate photos are one of the sneakiest storage killers on iPhone. They accumulate silently over years — burst shots you never cleaned up, photos imported twice, screenshots you forgot about, and near-identical shots from trying to get the perfect photo.

If you've ever looked at your camera roll and thought "why do I have so many photos?" — duplicates are probably a big part of the answer.

Here's how to find them and deal with them properly.

Why Duplicates Appear in the First Place

Before you start deleting, it helps to understand where duplicates come from:

Burst mode — holding down the shutter takes 10+ photos. You pick one favourite, but the rest stay in your library

Importing from old phones or computers — if you've migrated phones, photos sometimes get imported twice

WhatsApp and messaging apps — photos sent to you are saved alongside your camera roll photos

Screenshots of photos — you screenshot something, then later the original arrives in your camera roll

Near-duplicates — you take 3 shots of the same scene, keep all of them "just in case"

Method 1: Use iOS Built-in Duplicate Detection

Since iOS 16, iPhone has a built-in tool to find exact duplicates:

Open Photos on your iPhone

Tap Albums at the bottom

Scroll down to Utilities

Tap Duplicates

iOS shows you pairs (or groups) of exact duplicates and lets you merge them — keeping the highest quality version and deleting the rest.

This works well for exact duplicates, but it won't catch near-duplicates (slightly different shots of the same subject).

Method 2: Clean Up Burst Photos

Burst photos are a major source of duplicates that the iOS Duplicates album won't catch.

To find and clean them:

Open Photos → Albums → Bursts

Tap each burst to see all the shots

Tap Select to choose your favourite

Tap Done → Keep Only 1 Favourite

This deletes all the other shots in the burst except your selected favourite.

If you have hundreds of bursts, this can take a while. The Migrate Moments app makes this faster by surfacing burst groups for quick review.

Method 3: Use Migrate Moments for Near-Duplicates

The iOS Duplicates album only catches exact duplicates — identical files. It won't catch:

Two shots of the same scene from slightly different angles

Photos taken seconds apart

Screenshots alongside the original photo

Edited and unedited versions of the same photo

Migrate Moments Pro includes near-duplicate detection that finds these similar photos and presents them side by side so you can pick the best one and delete the rest.

Download [Migrate Moments](/ios) from the App Store

Tap Duplicates in the app

Review near-duplicate groups

Tap Delete on the ones you don't need

This is the most thorough approach — especially useful if you've been taking photos for years across multiple iPhones.

Method 4: Check Your Screenshot Album

Screenshots are technically not duplicates, but they're often photos of things you already have — screenshots of photos sent in messages, screenshots of things you looked up, screenshots of memes you forwarded.

Open Photos → Albums → Screenshots

Scroll through and delete anything you don't need

Select all if you want to start fresh

Most people can delete 80–90% of their screenshots without a second thought.

How Much Space Can You Free Up?

It depends on your library size and shooting habits, but typical results:

Burst cleanup — 1–5GB for most people, much more for regular burst shooters

Exact duplicates — typically 500MB–3GB

Near-duplicates — 2–10GB depending on how many similar shots you keep

Screenshots — 200MB–2GB

Combined, a thorough duplicate cleanup can free up 5–20GB for most people — often enough to drop a storage tier.

Should You Use a Third-Party Mac App?

If your library is very large (50,000+ photos), doing duplicate cleanup on your iPhone can be slow. The Migrate Moments Mac app lets you view and manage your library from your computer, which is faster for large-scale cleanup.

After Cleaning Up Duplicates

Once you've removed duplicates, a few things to do:

Empty Recently Deleted — deleted photos sit in the Recently Deleted album for 30 days before being permanently removed. Go to Albums → Recently Deleted → Delete All to reclaim the storage immediately

Wait for iCloud to sync — your iCloud storage won't update immediately. Give it 15–30 minutes

Check your storage — go to Settings → [Your Name] → iCloud → Manage Storage to see the new numbers

The Bottom Line

Duplicate photos are a silent storage thief. The iOS built-in Duplicates album is a good start, but it only catches exact matches. For a thorough cleanup, use a combination of burst cleanup, the built-in tool, and near-duplicate detection from Migrate Moments.

Most people are surprised how much space they free up — and how much cleaner and more enjoyable their photo library feels afterwards.
