If you shot a lot and have the habit of storing and managing photos on your Mac, duplicate photos may have accumulated on your Mac over time. Duplicate photos take up storage space and make viewing photos less enjoyable. Don’t worry. This article will show you how to find and how to delete duplicate photos on Mac easily and quickly.


Method 1. How to find and delete duplicate photos on Mac in macOS Ventura

Applies to: macOS Ventura only

With the release of macOS Ventura and the release of iOS 16, the duplicate detection feature finally comes to Apple Photos. If your Mac is running macOS 13 Ventura, then you can use the new duplicate detection feature built in to the Photos app to automatically find duplicate photos on Mac and then delete or merge them.

The Photos app in macOS Ventura has a Duplicates album. Clicking the album will display all the duplicate photos found in your Photos library. In addition to exact duplicates, it finds identical photos that have different metadata, resolutions, or formats. It also detects very similar photos.

You have two ways to handle the detected duplicates: merging or deleting.

  • There is a Merge option for each set of duplicate photos. Clicking the Merge option will automatically keep one photo and delete the rest photo(s) of this set. In addition, the data (such as titles and captions) you added to photos of this set will be merged into the kept photo.
  • Or, in a set of duplicates, you decide which one(s) to delete and then delete manually.

Either way, the deleted duplicate photos go to the Recently Deleted album.

Below are the steps.

1. On your Mac computer running macOS Ventura, open the Photos app.

2. Open the Duplicates album by clicking Duplicates in the sidebar.

Method 2. How to delete duplicate photos on Mac in the easiest way

Applies to: macOS 10.11 or later, including macOS 13 Ventura

Compared to the first method, this method has 3 major benefits. It’s applicable to various macOS versions, including newer ones and older ones. It allows you to easily and quickly remove all duplicate photos at once. It automatically finds duplicate photos in the Photos app and folders on Mac.

Let’s take a closer look.

This method uses a duplicate photo finder and remover app called Cisdem Duplicate Finder. The app can find duplicate photos and all other duplicate files on Mac, including those in the Photos app and in folders.

In addition to exact duplicates (photos that are exactly the same regardless of name), it finds near-duplicates and similar images.

In each set of exact duplicate photos found on your Mac, the app will automatically selects all but one for deletion. In other words, all duplicates are selected for you to effortlessly remove with a single click. If you are not happy with the auto selection, you can apply a selection rule to all or certain sets, or just select/deselect by hand.

In each set of near-duplicates or similar photos, you can easily preview photos side by side and manually select the redundant one(s) for removal. You can also use a selection rule to help you mass select if you want.

Below are the steps.

1. Download and install Cisdem Duplicate Finder on your MacBook Pro, MacBook Air, iMac or Mac mini. Open it.

2. To scan the Photos app or a folder for duplicate photos, add the Photos library or folder.

6. Click Delete to remove all the selected duplicate photos.

The duplicates removed from the Photos app will go to the Recently Deleted album in the Photos app and stay there for a month. To permanently eliminate them right away, you can click Delete All in Recently Deleted. The duplicate photos removed from folders will go to Trash.

Method 3. Manually find and remove duplicate photos on Mac for free via Finder

Applies to: All macOS versions

Unlike the previous two methods, this one doesn’t handle the duplicates in Mac’s Photos app. This method only deals with the duplicate photos in folders on Mac.

Finder is a file manager app included with macOS, helping you find and organize files and folders. Although Finder doesn’t provide a feature to search folders for duplicate files, its powerful search function can make it easy for you to manually find duplicate photos on your Mac.

1. Open Finder on your Mac.

2. Open the folder in which you want to delete duplicate pictures, such as Desktop or Downloads.

3. In the search field, enter the keyword “kind:image” and choose Image in the Kinds menu that appears.

4. Set Finder to search the folder you specify instead of This Mac.

5. Now Finder will list all the image files in your specified folder, including those in subfolders.

6. From the View menu at the top of your screen, choose the as Cover Flow option. Arrange photos by Size or Name.

7. Browse through the photos and identify the duplicates by visually comparing photos and checking photo information.

8. Select one or multiple redundant duplicate photos, control-click and choose Move to Trash.

9. Continue getting rid of other duplicates.

If you want to find a certain type of duplicate images, such as duplicate JPG files, you can enter the keyword “jpg” in step 3.


Can Mac’s Photos find duplicates?

Apple Photos, or simply Photos, is a photo management app developed by Apple. It’s available on Mac and iPhone. Mac’s Photos app can detect exact duplicates during importing.

Photos on Mac lets you delete or merge (only in macOS 13 Ventura) the duplicate photos that are found manually or by the duplicate detection feature. It doesn’t delete for you, which is the right thing to do.

How do I remove duplicates from iPhoto?

iPhoto is the predecessor of the Photos app. If you have an iPhoto library filled with duplicates, you can import the library to the Photos app and then use the first two methods to get rid of duplicate photos.


Keeping your photo library free from duplicates brings a better browsing experience and makes it easier to organize photos. This article shows you how to delete duplicate photos on Mac in different ways in different macOS versions (such as macOS Ventura, macOS Monterey, macOS Big Sur, macOS Catalina, macOS Mojave, macOS High Sierra, etc.). You can quickly remove duplicates all at once, easily mass delete multiple duplicates, or handle them one by one.
