If your iPhone 11, 12, 13, 14, 15, 16, or even the latest iPhone 17 is constantly running out of storage, duplicate photos are often a hidden culprit, especially on iOS 18 and earlier versions. Screenshots, burst photos, edited copies, and synced images can silently pile up.
In this guide, you’ll learn how to delete duplicate photos on iPhone, where to find them, and the safest ways to remove them efficiently without losing important memories.
Apple has significantly improved duplicate detection in recent iOS versions, but duplicates don’t always appear where users expect. Understanding where to look is the first step to effective cleanup.
On iOS 16 and later (including iOS 18), Apple introduced a built-in Duplicates album inside the Photos app. Here is how to see duplicate photos on iPhone:
Open the “Photos” app and tap "Collections/Albums” at the bottom.
Scroll down to the “Utilities” section and select “Duplicates.
Here, iOS automatically groups photos that appear visually identical or extremely similar, even if they have different file names or sizes.
A duplicate photo on an iPhone can include:
Not all duplicates are detected automatically. Common reasons include:
This is why the built-in tool is helpful, but not always complete.
Depending on your situation, there are several safe ways to delete duplicate photos on an iPhone.
Below are the most effective options, from built-in solutions to automated tools.
If you are wondering how to merge duplicate photos on an iPhone, there is a built-in feature for that which works fast and for free. It automatically keeps the best version of the images while deleting others, and is ideal for most users.
Open the “Photos” app on your iPhone and go to the “Utilities” section in “Albums/Collections”.
You will see groups of duplicate images. Tap the “Merge" button against a group, and the iPhone will automatically merge the duplicate photos. (See Part 1)
The built-in feature to merge duplicates may not work for every picture, and this feature is not available on older iOS versions. That’s where you can do it manually, especially for identical images and screenshots.
Here is how to merge duplicate photos on an iPhone manually:
Open “Photos” and go to “Library” or “Albums”.
Tap “Select” and choose duplicate images one by one.
Tap the “Trash” icon and confirm deletion. These images will stay in the “Deleted Photos” album for 30 days and will be deleted automatically afterwards.
When you have thousands of photos, and Apple's built-in detection isn’t enough, a third-party app can help. Clever Cleaner works automatically and allows bulk deletion in seconds with its user-friendly interface. It is a great tool when you are upgrading from an older iPhone, and you are a heavy Photos user.
Bulk delete photos from iPhone using Clever Cleaner with the following steps:
Install Clever Cleaner from the App Store, then open it and allow photo access permissions.
Start a scan by tapping on the “Smart Cleanup” button.
Review detected duplicates and tap the "Move to Trash" option to delete duplicates in bulk.
If your iPhone photos are synced to your Mac via iCloud, cleaning duplicates from the Mac side is often faster and more controlled. It provides a large-screen review experience, and an advanced duplicate detection system ensures safe cleanup without losing any data.
Cleamio on Mac works when your photo library is synced via iCloud, and you want to delete the duplicate files from all your synced devices with an easy experience. Managing duplicates on an iPhone's small screen can be hectic and time-consuming when you have thousands of images.
So, taking it on a Mac makes it feel effortless for you, and if you delete something accidentally, you can still recover from iCloud's Recently Deleted album, bringing a second layer of safety.
Here is how to mass delete duplicate photos on iPhone with Cleamio.
Download and install Tenorshare Cleamio on your Mac and open it, then select the "Similar Photos" feature. Click the "+" button and add your "Photos Library" then click "Scan".
(Optional) You can go to the Cleamio Preferences to adjust the image similarity you want before scanning.
Cleamio will display all the similar images in your library. You can click to choose them and click the "Remove" button in the bottom right to delete them. Click "Completed" to finish the process, and you are done.
Since you have synced your iPhone Photos Library with your Mac using iCloud, these duplicate images will be deleted from your iPhone automatically.
