Our take: A dedicated duplicate photo finder for Mac with support for Lightroom

Designed to handle image files, PhotoSweeper fully supports all popular image formats and a few RAW formats. The support for RAW photos is a benefit for photographers particularly.

It is capable of finding almost all the duplicate photos in a folder you specify. It can also scan a location on your Mac for similar photos. Due to the algorithm it uses compare images and identify duplicates, the speed may be a little slow sometimes.

If the app crashes or freezes when scanning a large photo library or folder, don’t worry. Quit or force quit the app. Relaunch it and perform the scan again.

Our take: A duplicate photo finder for Mac with multiple modes to scan for duplicate pictures

Dedicated to locating the duplicate image files on a Mac for users to bulk delete, Duplicate Photo Cleaner supports all popular image formats including some RAW formats.

Highly customizable, it allows you to scan only specific formats of images for duplicates. It also offers multiple scan modes (such as Folder Comparison mode). You have full control over what duplicates to find and where to find.

When it finishes scanning, it will display duplicates in groups for you to view. But note that sometimes there can be something wrong with the displaying. In the test, it displayed four identical images into two groups instead of one group.

In addition to identical photos, it can help you find photos that are nearly identical (such as visually similar photos). You can adjust the Similarity Threshold value to get more desired scan results.

Our take: Equipped with two customizable modes to find duplicate photos and similar photos on Mac

Lightweight and compact, it’s one of the best duplicate photo finders available for Mac users. It offers two modes.

To look for duplicate images only, enable Exact Match mode. To find both duplicate and similar images, switch to Similar Matches mode, which lets you compare images by content, size and metadata (such as time and location).

Before a scan, you can configure settings in Preferences. For example, you can go to the Filter & Sort tab to exclude certain images from scan by file size or image format.

#7 Duplicate Cleaner for iPhoto (free)

Compatibility: macOS 10.7 or later

Latest version: 1.28, released in March 2022

Our take: A free app that can find most of the duplicate photos on your Mac

If you are looking for the best free duplicate photo finder for Mac, you can check out Duplicate Cleaner for iPhoto. Don’t let the app’s name fool you. In addition to iPhoto, it can find and delete duplicate pictures in folders and the Photos app.

In the test, this app took more than one minute to search for duplicates, where most other apps only took several seconds. I used this app to scan a folder where 62 groups of duplicate photos existed, and it found 60 groups, which is pretty acceptable.

Despite being freeware, this app provides a great preview feature and a useful Auto Mark feature. If you don’t want to spend time manually selecting individual duplicates to delete, just click the Auto Mark button.

Pros

Cons

  1. Pretty slow

  3. Limited customizability

#8 dupeGuru for Mac (free)

Compatibility: macOS 10.12 or later

Latest version: 4.2.1, released in March 2022

Our take: The best duplicate photo finder Mac free app that is open source

dupeGuru has been around since 2004. Users needed to pay to use it until 2010 when the developer Hardcoded Software announced that its apps became free and open source.

It used to offer the Picture Edition and the Music Edition. And later the functionalities from the two editions were packed in one app.

Now dupeGuru offers three scan modes: Standard, Music and Picture. To use dupeGuru to locate and eliminate duplicate images on Mac, you can use the Standard mode or the Picture mode. To my surprise, the former is actually better according to the tests.

In the tests, the Standard mode found more duplicate photos and was very fast. The Picture mode missed several groups of duplicates and was painfully slow.

But you need to use the Picture mode if you want to find similar photos on Mac.

Pros

  1. Free to use and open source
  2. Can find duplicate photos, audio files, video files and more
  3. Can also detect certain similar photos
  4. Provide 3 scan modes
  5. Easy to customize

Cons

  1. Can’t find duplicates in Mac’s Photos app
  2. The Picture mode can be very slow
  3. Crash when scanning a large folder
  4. Not easy to preview

    Hey, Rosa Reyes! Nice name, where are you from? I am Venezuelan. :) Thank you a lot for this post! Most apps did not help me, but the free one kind of did. It is nice to find such in-depth review of these apps, because right now I have a 10,000-items Finder Folder, and I am pretty sure every two of them are duplicates. :P
