Find and Delete Duplicate Photos on a Mac

If you’re like most people, you probably save a lot of photos on your Mac. However, this can lead to duplicate photos cluttering your storage space, making it difficult to find the images you actually want. In this article, we’ll show you how to find and delete duplicate photos on Mac so you can free up space and organize your photo library.

Understanding the Origins of Duplicate Photos

There are several reasons why this is happening:

  • Copying or importing photos from different devices: If you import photos from various devices, you might obtain duplicates if the files have different names or import the images carelessly.
  • Photo editing and versioning: When editing a photo and saving multiple versions, you might end up with duplicates of the same image.
  • Syncing errors and backup restoration: You might get duplicate copies if you’ve restored from a backup or synced your photos to multiple devices.
  • Sharing and receiving photos: If you send or receive pictures from others via AirDrop or download images from those sent to you via email or on any social media platform, your library might end up with duplicates.
  • Merging photo libraries: If you combine multiple photo libraries, you may end up with duplicates if the same photo exists in both libraries.

Best Methods for Finding and Deleting Duplicate Photos on a Mac

If you want to get rid of duplicate photos on Mac, try doing one of the following methods:

Method 1: Identify Duplicate Photos Manually

If you have a relatively small photo library, you can identify duplicate photos manually. Here are three options for doing so:

Option A: Use Finder to search for duplicate file names

  1. Go to Finder, select File, then choose Smart Folder from the menu.

  2. Select + from the upper-right corner of the screen.
  3. From here, you can search for duplicate files on your Mac. You can select a particular folder or choose This Mac if you want to scan your entire Mac’s drive for duplicate files.
  4. Choose Kind from the drop down menu on the first column and Image on the second column.

  5. Go through the results and sort them by file name. Check the images with the same file name, and open them to confirm if they are duplicates.
  6. Delete the duplicate file by right-clicking it, and select Move to Trash.

Option B: Sort photos by date in Photos app

By default, the Mac Photos app keeps a sort from oldest to newest to showcase all photos and videos from your photo library. Here’s how you can sort photos by date using the Photos app:

  1. In selecting a photo album, click the View from the menu bar, then choose Sort.
  2. You will be shown four sorting options: “By Date Added”, “By Name”, “By Oldest First”, “By Newest First”. That’s all the sorting options that the Mac Photos app can offer.

Option C: Compare visually similar photos

  1. Open the Photos app on your Mac.
  2. Navigate to the album or folder containing the photos you want to check for duplicates.
    check for duplicates
  3. Select the first photo you want to compare.
  4. Scroll through the album or folder and select the second photo you want to compare.
    select photo to compare
  5. Click on the Info button in the top-right corner of the Photos window.

  6. Compare the details of the two photos, such as the date and time, location, and file size. If the details are identical, the images may be duplicates.
  7. To confirm whether the photos are duplicates, use the zoom feature in Photos to examine the images closely. If the images appear identical or nearly identical, they are likely duplicates.
  8. If the photos are duplicates, select one and delete it by pressing the Delete key on your keyboard or right-clicking on the image and selecting Delete Photo.

Repeat the above steps for each set of visually similar photos until you have identified and deleted all duplicate images in the album or folder.

Method 2: Use Built-in Features and Third-Party Tools

If you have a large photo library, or if you’d rather use automated tools, there are several options available:

Option A: Smart Albums in the Photos app

  1. Go to the Photos app.
  2. In the menu bar, click File and create a New Smart Album by clicking New Smart Album.
    select new smart album
  3. On the first drop-down menu, select date captured, and in the second drop-down menu, input a particular date. There are also other options you can select on the drop-down menu, such as album, file name, person, and more. Select the one that best suits what you’re looking for.
    select data captured
  4. Click OK. From there, the Photos app will show you pictures based on your input date if you selected ‘date captured’.
    click ok after inputing date
  5. Manually take a look at any duplicate photos and delete all duplicates.
