It is easy to generate duplicate photos on iPhone. For example, some people like to capture photos in burst mode, resulting in a large number of slightly different photos. If you sync your photos across multiple devices using the cloud service like iCloud, duplicate photos may also be created in the sync process. Duplicate photos can be annoying, which not only takes up valuable storage space, but also makes it difficult to organize photos.

Cisdem Duplicate Finder is an excellent and easy-to-use duplicate photo finder for iPhone. This free app detects duplicate photos in the Photos app on your iPhone, regardless their filenames. It also identifies similar photos by comparing actual image content, allowing you to customize the level of similarity desired to search for similar photos.
It categorizes all the duplicates it finds into three categories: Duplicate Photos, Similar Photos and Duplicate Videos. Exact same photos are categorized into “Duplicate Photos", which are typically generated when you download a photo multiple times, or sync the same photo from different sources. In the "Similar Photos" tab, you can find not 100% identical duplicates, such as those look the same but have different file sizes, resolutions, or similar looking photos. The default matching level for similar scan is 60%, which can find a good number of duplicates. If you are not satisfied with the similar images it finds, you can adjust the Histogram similarity and Features similarity in the Settings to better suit you needs and rescan.
It scans your entire photos library for duplicates. If you have a lot of photos on your iPhone, you can wait a few minutes for the scan to complete, or stop the scan midway and view instant results. It automatically selects all but one photo in each set of duplicates for removal. You are also allowed to view the duplicate photos details and manually select unwanted items to delete, or let this tool batch select duplicates for you based on the selection rule of your choice, including Select oldest, Select low-quality, Select by filename, etc.
The deleted photos will be removed to the Recently Deleted album in the Photos app on your iPhone.
Applies: iOS 15.0 or later

Develoed by DevMeApp, Cleanup app is specially designed to clean up duplicates in your photos library. Once you install this duplicate photo finder on your iPhone, it will ask you for permission to access your Photos and instantly scan it for useless files.
It divides all the files it considers useless into five categories: Duplicates, Similar, Videos, Similar Screenshots, and Other. It lets you delete all duplicate photos at once and keep the original. As for similar images, it also suggests the best results for you to help you delete in bulk. But I don’t recommend using the one-click delete function. After testing, I don't think the similar images it finds are always accurate. You'd better go through each set of images one by one and select the unwanted ones to delete manually. If you think both similar images are necessary, you can add them to the Keep List by clicking the Keep All button in the upper left corner of the set of images. This tool also lets you review all the photos, videos in your photos library and sort them by size or date. Then you can quickly delete unneeded photos and videos that take up space on your iPhone.
In addition to removing duplicates, Cleanup app also offers some other useful features. Such as hide your private photos & videos by creating a PIN, merge duplicate contacts.
Applies to: iOS 16.0 or later

Designed for cleaning up digital space, CleanMy®Phone is one of the best duplicate photo finder for iPhone. Unlike the previous two apps with simple and clean interfaces, this one is colorful, making you less annoyed when dealing with large numbers of disorganized files.
Open this duplicate photo finder for iPhone. Give it permission to access the photo roll. Go to the “Declutter” tab. Then you can start searching for duplicate photos on your iPhone by clicking the “Scan” button on the main window. It categorizes and groups all your photos with the help of AI-powered technology. If you want to clear duplicate images, click on “Duplicates” from the search results. This app also comes with auto select rules that identify copies and helps you keep the best picture on your iPhone. However, like with some other apps on the list, it’d be better to preview the photos carefully before cleaning them.
Applies to: iOS 13.0 or later
Best for: Eliminate duplicate photos, videos and contacts on your iPhone with 1 click.
Cleaner-Clean Duplicate Item for iPhone isn't designed specifically to clean up duplicate photos, but it also offers a nice duplicate photo finder feature. It helps save space on your phone by looking for duplicate photos, videos, and similar photos. Additionally, it further categorizes the similar photos it finds into different tabs: Similar Photos, Similar Live Photos, and Similar Burst Photos. Let you handle duplicates in your photos library more clearly.
The tool also has a built-in preview pane that allows you to preview the image before removal. However, each set of duplicates is displayed as one image larger and the other smaller, making it difficult to clearly compare the two images. Be careful when cleaning similar images. If trust the smart selection of it, you can click the “Select All” button in the upper right corner to remove all duplicates with 1-click.
Cleaner also has a feature that is better than other duplicate photo finders for iPhone in dealing with photos. It lets you compress the size of photos. For example, when you have many similar images that take up much space on your phone, but want to keep all of them. You can compress them instead of deleting, which can also save a lot of space.
In addition to duplicate photos, videos, Cleaner app also helps find and merge duplicate contacts on your iPhone.

Unlike other duplicate photo finder for iPhone in this article, Duplicate Photos Fixer doesn’t provide a free trial. You will be charged for it before you can use the app.
It does an excellent job of scanning and cleaning duplicate images on your iPhone device. And it supports most popular image formats like JPEG, BMP, GIF, Apple Icon Images, MacPaint Images, TIFF, RAW, ProRAW, and many others. The best part about this tool is that it allows you to choose the type of scan you want to run on your device, including Normal scan mode (search photos that are similar enough), Aggressive (Search photos that are similar), and Custom mode (Search similar photos with custom settings). The Normal scan mode will be fine for most users. The Custom mode lets you control the matching level, bitmap size, time interval, etc.
Once the scan is completed, the results will be displayed in the form of image groups. You can click the Trash icon in the lower right corner to immediately delete all duplicates that have been automatically marked.

dodo – remove duplicate photos is a lightweight, simple, easy-to-use utility designed to detect similar images. Its scanning speed is very fast. I opened the app and it immediately showed me the results of search. However, the search quality is not very good. Some of the similar images it founds are completely different things.
It sorts the images by creation date, with the newest at the top of the list. Unlike other duplicate photo finders for iPhone I mentioned above, this tool does not have any options to automatically mark duplicate photos for deletion. To remove duplicates, all you need to do is to scroll down and choose the photos you wish to delete, click the “Delete All” or “Keep All” button at the bottom of the photo. The deleted photo will go to the “Recently Deleted” album in your Photos app.
Yes. The Photos app on iPhone has built-in duplicates detection to help you find and merge duplicate photos, videos easily. But its detection is not instantaneous. It usually takes several months for the duplicate photos to be detected. It also isn't very good at detecting similar photos, and fails to find photos that look similar, such as those taken from different angles.
You can open Photos app on your iPhone. Tap Albums and scroll down to find Duplicates album under Utilities. And the detected duplicates will be placed there.
Can’t see the Duplicates Album in the Photos app on your iPhone? Here are some common reasons:
1. Your iPhone is not updated to iOS 16.
2. The Photos app is still in the process of detecting duplicates.
3. There are no duplicate photos in your photos library.
It’s almost impossible to avoid duplicate photos from appearing over time. However, duplicates make our photo library clutter and take up much space. Maybe you tried the built-in detection in the Photos app but it didn't meet some of your needs. In this article I showed 7 best duplicate photo finders for iPhone. They all do a great job of finding duplicates!
