The fastest way to find and remove duplicates
The easiest method depends on what device you use. On iPhone, the Photos app has a built-in tool that finds near-identical shots taken seconds apart — go to Albums, tap See All, then look for Duplicates. On Android, Google Photos shows a Duplicates album if you have the app installed. On Windows, the Photos app also flags duplicates automatically. On Mac, you can use the Photos app the same way as iPhone, or use a free tool like Gemini Photos if you want more control over what counts as a duplicate.
All of these tools work by comparing images pixel-by-pixel or by looking at file metadata — the hidden information stored with each photo. If two images are nearly identical, the tool marks one for deletion. You review the suggestions before anything is removed, so you will not accidentally delete a photo you wanted to keep.
The reason to use your device's built-in tool first is that it only flags true duplicates — photos that are so similar they serve no purpose to keep both. Third-party apps sometimes flag photos as duplicates when they are actually different shots from the same burst sequence, which is why the built-in options are safer for most people.
Key Takeaways
- iPhone and Mac users can find duplicates in the Photos app under Albums > See All > Duplicates, and the app will suggest which copy to delete.
- Android users with Google Photos installed can view suggested duplicates in a dedicated Duplicates album within the app.
- Windows users can open the Photos app and look for duplicate suggestions, or use a third-party tool if the built-in option does not find what you need.
- Always review the app's suggestions before deleting, because some tools flag similar photos that you may want to keep separate.
- Duplicates usually happen when you take burst photos, sync the same folder to multiple devices, or accidentally import the same batch twice.
How to delete duplicates on iPhone and iPad
Open the Photos app and tap Albums at the bottom of the screen. Scroll down and tap See All under the Utilities section. You will see an album called Duplicates — tap it. The app shows pairs of photos side by side, with one marked as the duplicate. Swipe left on the duplicate photo and tap Delete, or tap Select and then Delete All to remove all suggested duplicates at once.
If you do not see a Duplicates album, it means the Photos app has not found any near-identical images yet. This can happen if your duplicates are not close enough matches — for example, if one is cropped or edited differently. In that case, you will need to delete them manually by finding them in your library, swiping up on each one, and tapping Delete.
After you delete duplicates from the Photos app, they move to Recently Deleted, where they stay for 30 days before being removed permanently. If you change your mind, you can recover them during that window by opening Recently Deleted, tapping Select, choosing the photos you want back, and tapping Recover.
How to delete duplicates on Android with Google Photos
Open Google Photos and tap your profile picture in the top right corner. Go to Settings, then tap Photos settings. Scroll down and look for a Duplicates section — if it appears, tap it to see photos the app has flagged as duplicates. Google Photos shows them in pairs, with one marked for removal.
Tap the duplicate photo (the one marked for deletion) and then tap the trash icon to delete it. Unlike iPhone, Google Photos does not show all duplicates in one place — the app only flags the most obvious matches. If you have duplicates that are slightly different (different crops, different edits), you will need to find and delete those manually.
To delete duplicates manually on Android, open Google Photos, find the photo you want to remove, tap it to open it full-screen, then tap the three dots in the top right corner and select Delete. The photo is moved to Trash, where it stays for 60 days before being permanently removed.
How to delete duplicates on Windows
Open the Photos app (the built-in Windows app, not a web browser). The app scans your Pictures folder automatically. Look for a Collections section or a Duplicates option in the left sidebar. If you see Duplicates, tap it to view photos the app has flagged as identical or near-identical.
Select the duplicate photo you want to delete and press the Delete key on your keyboard, or right-click and choose Delete. Windows will ask whether you want to move it to the Recycle Bin or delete it permanently. Choose Recycle Bin so you can recover it if you change your mind.
If the Photos app does not show a Duplicates section, it means it has not found any matches. You can also use Windows File Explorer to browse your Pictures folder manually and delete duplicates by hand — right-click each unwanted photo and select Delete.
How to delete duplicates on Mac
Open the Photos app and click Albums in the sidebar. Scroll down to Utilities and click See All. You will see a Duplicates album — click it to view photos the app has flagged. Photos shows them in pairs, with one marked as the duplicate. Click the duplicate photo and press Delete, or select multiple duplicates and click Delete to remove them all at once.
Deleted photos move to Recently Deleted, where they stay for 30 days. If you need to recover a photo, click Recently Deleted, select it, and click Recover. After 30 days, the photos are permanently removed from your Mac.
If you want more control over what counts as a duplicate, you can use a third-party app like Gemini Photos (available free from the Mac App Store). Gemini lets you set how similar two photos need to be before the app flags them as duplicates, which is useful if you have burst sequences or similar shots you want to keep.
Why duplicates happen and how to prevent them
Duplicates usually appear for three reasons: burst mode (when you hold down the shutter button and the camera takes multiple shots in quick succession), syncing the same folder to multiple devices, or importing photos twice by accident. Burst mode is the most common cause — your phone takes 10 or 20 photos in a second, and you only want to keep the sharpest one.
To prevent duplicates from burst mode, review your burst sequences right after you take them. On iPhone, tap a burst photo in your library, then tap Select to choose which frames you want to keep and which ones to delete. On Android, open a burst sequence in Google Photos, tap the three dots, and select Keep Only These Photos to remove the rest of the burst.
To prevent duplicates from syncing, avoid importing the same folder to your phone twice. If you use cloud storage like Google Drive or iCloud, make sure you are not also importing the same photos through a USB cable or email. If you use multiple devices, turn on automatic syncing in one place — either your phone's cloud app or your computer — rather than syncing manually to both.
When to use a third-party duplicate finder
Third-party apps like Gemini Photos, Duplicate Photos Cleaner, or CleanMyMac are worth considering if your device's built-in tool does not find the duplicates you know are there. This usually happens when the duplicates are not pixel-perfect matches — for example, one is slightly cropped, or one has been edited while the other has not.
The trade-off with third-party apps is that they sometimes flag photos as duplicates when they are actually different shots you want to keep. Always review the app's suggestions carefully before deleting. Read the app's reviews on your device's app store to see whether other users report false positives.
Free versions of these apps usually show you the duplicates but charge a fee to delete them. Paid versions (typically $5 to $15) let you delete without limits. For most people, the built-in duplicate finder on your device is enough — third-party apps are most useful if you have thousands of photos and the built-in tool is too slow or too conservative.
Frequently Asked Questions
Will deleting duplicates free up storage space?
Yes, but only if you delete the actual files, not just remove them from an album. When you delete a photo from the Photos app or File Explorer, it frees up the storage space it was using. If you only hide duplicates or move them to an archive, they still take up space on your device.
Can I recover a photo after I delete it permanently?
If you deleted it less than 30 days ago (on iPhone or Mac) or 60 days ago (on Android or Windows), you can recover it from the Recently Deleted or Trash folder. After that window closes, the photo is permanently gone and cannot be recovered unless you have a backup.
What if the app marks two photos as duplicates but they are actually different?
Do not delete them. Tap or click elsewhere to deselect, and the app will not remove them. This is why reviewing suggestions before deleting is important — if you are unsure, keep both photos. You can always delete them manually later if you decide you do not need them.
Do I need to delete duplicates from cloud storage separately?
Yes. If your photos are backed up to Google Photos, iCloud, or another cloud service, deleting them from your device does not remove them from the cloud. You need to open the cloud app or website and delete them there as well. Some cloud services have their own duplicate-finding tools — Google Photos has a Duplicates album you can access from any device.
Why does my phone keep creating duplicates even after I delete them?
This usually means you are syncing the same folder in two different ways — for example, both through iCloud and through a USB import. Check your sync settings and make sure you are only syncing from one source. On iPhone, go to Settings > [Your Name] > iCloud > Photos and make sure iCloud Photos is turned on or off consistently. On Android, check that you are not importing the same folder through both Google Photos and another app.
