How to Delete Duplicate Photos on iPhone

Burst shots, photos you saved twice, the same selfie in ten takes, spam from group chats. That is how your gallery fills up with duplicates without you ever noticing. For most people, thousands of near-identical photos just sit there, repeating themselves and eating up precious storage. The good news: you can clean it all out, and it does not take hours. In this guide we will walk through the difference between exact duplicates and similar photos, the built-in tools on iPhone and Android, and the fastest way to get the job done.

First things first: exact duplicates vs. similar photos

Before you start deleting, it helps to understand that there are two completely different kinds of clutter here, and each one has its own fix.

• Exact duplicates - the very same image, saved two or three times. This happens when you re-download a photo you already have, send a file to yourself, or a backup syncs twice. The file is completely identical.
• Similar photos - not the same image, but very close. Ten shots from the same moment, a burst of your kid running, five selfie attempts before one came out right. The files are different, but in practice you only need one of them.

This distinction matters, because Apple's built-in tools can only handle the first type. The similar series, which are usually by far the biggest chunk, have to be filtered a different way.

The built-in "Duplicates" album on iPhone (iOS 16 and up)

Starting with iOS 16, Apple added a dedicated album that detects duplicates automatically. This is the first step worth taking, and it is completely free.

1. Open the Photos app, go to the Albums tab, scroll all the way down to the "Utilities" category, and tap "Duplicates".
2. If your device found any duplicates, they appear in pairs or groups, each with a "Merge" button next to it.
3. Tapping "Merge" keeps the highest-quality version (best resolution, location and depth data) and moves the rest to "Recently Deleted".
4. You can also tap "Select" in the corner and merge several groups at once, which saves a lot of taps.

Worth knowing: duplicate detection runs in the background and takes its time, especially on a large library. If the album is empty or missing, wait a day or two with your device charging and connected to Wi-Fi, and it will update. And as we already hinted, this album only catches near-identical copies, not the similar-photo bursts.

The real problem: series of similar photos

Most of the wasted space in your gallery is not in exact duplicates but in series of similar photos. You frame the view, shift the phone a little, shoot again, and again. You end up with eight near-identical versions when you only want to keep one. The "Duplicates" album simply does not see these, because at the file level they are different photos.

To catch them you need visual detection, the kind that compares how the photos look rather than just their file signature. This is exactly where AI comes in: it reads the content of each photo, groups together the ones that look alike, and shows them to you as a single cluster. We explained this in depth in our guide on how AI detects duplicate and similar photos, if you want to understand what is happening behind the scenes.

How to pick the best photo to keep

The part that eats the most time is not the deleting, it is the decision: out of ten similar photos, which one do you keep? Here are a few rules of thumb that speed up the call.

• Sharpness above all - one blurry photo is not worth a thousand words. Zoom in for a second to check that the eyes and faces are in focus.
• Open eyes, natural smile - in group shots, this is usually the deciding factor.
• Lighting and composition - the same scene can look completely different when the light falls just right.
• Resolution - if you have a full HEIC version next to a compressed screenshot of it, keep the original.

When it is hard to choose between two versions, it really helps to see them side by side instead of jumping back and forth. We wrote about this approach in our guide on comparing photos side by side, and it takes a lot of the guesswork out.

Manual vs. automatic deletion

It is tempting to let an app delete everything automatically, but remember: only you know that the blurry photo is of a grandmother who is no longer with us. That is why the healthy approach is a hybrid one. Let the AI do the heavy lifting, grouping and flagging the best shot in each cluster, but keep the final say for yourself.

In practice that means you move through the groups at a quick pace, confirming the AI's pick when it is right and stepping in only when you want to keep a different photo. That way you get the speed of automation without the risk of a blanket delete.

How Tidy finds and deletes similar photos with a swipe

Tidy is built exactly for the second type, the similar photos. The AI runs directly on your device, scans your library, and automatically groups every series of photos that look alike. In each group it flags the version it thinks is best, and shows them to you full screen.

From there it is simple: swipe left to mark for deletion, swipe right to keep. No dialogs, no one-by-one confirmations, just a single thumb motion per decision. Everything you mark goes into a review stack, and the photos are only deleted after you confirm with a single tap. Nothing disappears without your consent, and it all stays on your device, with no photos leaving your phone and no account required.

A nice bonus: sometimes the same person shows up several times in Apple's "People" album because of different angles. If that happens to you, we have a separate guide on fixing duplicate people in the People album that sorts out that mess too.

What about Android?

Android phones fill up with duplicates too, and the solutions are similar in principle. Google Photos has a "Manage storage" tool that suggests deleting blurry photos and screenshots, but it does not truly group similar series together. Some device makers, like Samsung in its own Gallery, offer basic duplicate detection through the storage menu.

The upside: Tidy is also available on Google Play, and the same AI detection that groups similar photos works the same way on Android. So no matter which phone you are on, the approach is identical.

How to prevent duplicates in the first place

Cleaning up is good, but preventing is better. A few simple habits will save you this work in the future:

• Turn off auto-save in WhatsApp - Settings, then Chats, then turn off "Save to Camera Roll". This is the number-one source of duplicates and needless buildup.
• Go easy on long burst shots - holding the shutter produces dozens of frames per second. Save them only when you really need to capture motion.
• Delete right after sharing - if you took a screenshot just to send it, delete it the moment it is out.
• Do a quick cleanup once a week - a few minutes each week prevents thousands of photos from piling up.
