If you shoot a lot with your camera or smartphone and tend to store the photos on your Mac, then chances are high that lots of duplicate photos have accumulated on your Mac over years. Deleting duplicate photos can help you free up space on Mac and better organize photos. Free duplicate photo finder Mac software is available, which is supposed to help you weed out duplicates for free.

Are free duplicate photo finders really free? How good are they at finding and removing duplicates? Please read on.

Are some free Mac duplicate photo finders really free?

Many apps claim to find and remove duplicate photos on Mac with no cost to users, but they don’t as a matter of fact. Users have to pay to perform the deletion, or they are only allowed to delete a limited number of the found duplicates for free. A totally free one should let users find and delete without limit.


6 truly free duplicate photos finders for Mac

There are a few truly free apps available. But are they any good?

Disk Drill

Provided by: 508 Software

Compatibility: macOS 10.11 or later

Latest version: 4.2.274, released on 23 Feb 2021

Disk Drill

Primarily designed as a data recovery app, Disk Drill can also find duplicate photos, videos, songs, documents and more (for free). It’s recommended by some as the best free duplicate photo finder for Mac.

This free app can find the duplicate photos in a Mac folder. However, it can’t find all duplicates sometimes. Also, it works extremely slowly when scanning a large folder or drive for duplicates. And, a preview feature, which is essential, is missing.

What’s more, it doesn’t support Mac Photos app. We can store photos on a Mac by importing them to Mac Photos app or to a regular folder. The former is what we usually do. Therefore, support for Photos is important.

In the test, when I tried to scan the Photos Library (where photos in Photos app are stored) using Disk Drill, it failed to detect the duplicates in it.


  1. Find duplicate photos, videos and more
  2. Also help with data recovery


  1. Can only find duplicate photos in folders
  2. Can’t work with Photos app at all
  3. Very slow scanning
  4. Fail to find all duplicates sometimes
  5. No preview feature

Duplicate File Finder

Compatibility: macOS 10.12 or later

Latest version: 6.13, released on 19 Mar 2021

Duplicate File Finder

Duplicate File Finder, also called Duplicate File Finder Remover, is an app to check for and delete duplicate pictures and other types of duplicate files on Mac computers.

It can scan both regular folders and Photos Library for safe duplicates removal. However, if your have a library with more than 5 thousands, the scan will be painfully slow.

When the app finishes scanning, it will list the found duplicate photos in the results window. There, you can preview photos and see information like file size and creation date. 

The app provides an Auto-Select feature. In each group of duplicate photos, one photo will be kept untouched and the rest will be automatically selected for removal. You don’t have to do it by hand.


  1. Find duplicate images, videos and other duplicate files
  2. You don't have to select dupes to delete by hand


  1. Painfully slow when scanning a big photo library
  2. Sometimes can’t find all duplicate photos as claimed
  3. Sometimes wrongly delete similar images as duplicates
  4. Can’t preview photos side by side

Photos Duplicate Cleaner

Compatibility: macOS 10.7 or later

Latest version: 2.6, released on Mar 30, 2021

Photos Duplicate Cleaner

Dedicated to handling images, this free duplicate photo finder for Mac can work with both Photos Library and the regular folders. When scanning Photos Library, it will ask you to quit Photos app first if Photos is running.

In the test, it couldn’t find all the duplicates. A couple of exact duplicates were missed. Also, sometimes a scan may fail and you need to perform a scan again and again until it works properly.

The detected duplicate photos are listed in the results window as big thumbnails. Therefore, you can handily preview and compare duplicates side by side.

This app has an Auto Mark feature, help save a lot of time when there are tons of duplicates to get rid of.


  1. Make it easy to preview and compare photos
  2. Save you from manually selection by offering the Auto-Mark feature


  1. Only find some duplicate photos
  2. Sometimes duplicates remain after being "removed"
  3. Sometimes fail to scan, requiring you try multiple times
  4. Corrupt Photos Library in rare cases
  5. Unexpectedly crash sometimes

Araxis Find Duplicate Files

Provided by: Araxis Ltd

Compatibility: macOS 10.6 or later

Latest version: 2013.433, released on 12 Feb 2013

Note that the app is discontinued. It may have compatibility issues with newer macOS versions.

Supporting various types of files such as images, archives, music files and documents, it can detect most of the duplicate images and other duplicates in a folder on Mac.

However, it’s not designed to scan Photos Library for duplicates. Therefore, it’s far from being a good Apple Photos duplicate finder.

An Apple Photos duplicate finder should only check the actual photos in your library in order to find the duplicates among them and shouldn’t touch any other data in the library. But Araxis Find Duplicate Files will check both the photos and the data. If you remove the found duplicates as the app suggests, your Photos Library will get damaged.


  1. Find common types of duplicate files


  1. Can’t find all duplicates
  2. May damage your Photos Library
  3. Not well compatible with new macOS versions
  4. Crash when scanning a large amount of photos
  5. Discontinued

Duplicate Finder & Remover

Provided by: Praksh Jat

Compatibility: macOS 10.11 or later

Latest version: 1.0.3, released on 7 Sept 2020

This free duplicate photo finder for Mac doesn’t allow you to scan Photos Library. If you have the habit of storing your photos in a folder instead of Photos, then you can try to use it.

Like the apps above, this app too can only find some of the duplicate photos.

The app used to be available on the Mac App Store but was removed. It doesn’t have an official website. So you have to get its from other sources, which may not be reliable. Think twice before you install it on your Mac computer.


  1. Support images, videos, documents and other file types


  1. Can’t find duplicates in Apple Photos Library
  2. Not good at finding all duplicates
  3. No side-by-side preview
  4. No legitimate source of download

Duplicates Finder

Provided by: WinZip Computing LLC

Compatibility: macOS 10.7 or later

Latest version: 1.0.0, released on 12 Apr 2016

This freeware app can scan both folders and Photos Library for duplicates. However, it may damage your Photos Library, just like Araxis Find Duplicate Files would do.

The app is capable of identifying most of the duplicate photos in a folder on your Mac. The duplicates will be listed in the results window in groups. You have to manually select the unwanted duplicates one by one and then click the Remove Selected button to get rid of them. There is no way to do it automatically.


  1. Support all common file types


  1. May harm your Mac Photos Library
  2. Can’t find all dupes
  3. Can’t deal with a big photo collection
  4. Have to manually select duplicates to delete one by one
  5. Display no preview at all


There aren’t many truly free duplicate photo finders available for MacBook Air, MacBook Pro, iMac, etc. I have tested the ones that I can get my hands on.

As you can see, they may have some features that you expect from duplicate photo finder software, such as automatically identifying duplicates. But they are not good at it.

All the free apps can’t deal with the Apple Photos app for Mac – where duplicate photos usually reside on a Mac. To make matters worse, they may damage Photos Library.

Not to mention their inability of finding all duplicates and handling a large number of photos. Some of the free duplicate photo finders for Mac may crash, and some of them are pretty slow. You may spend much time trying these apps but end up still having the duplicate photos on your Mac.
