Our reality is this: we capture over 5 billion photos worldwide and share 14 billion images on social media each day. It’s become second nature to snap dozens of photos to get the perfect one, save the same meme multiple times, or take countless screenshots.

Over time, these habits add up, especially when we forget to organize files, filter our galleries before syncing with our Macs. As a result, Mac is drowning in duplicates. Luckily, you don’t have to sort through every image manually. With the right photo cleaner tool, you can find similar photos on Mac and delete unnecessary ones in several clicks.

In this guide, you’ll learn why you need such a photo cleaner and what options you have. We’ll go through each option’s pros vs cons so you can pick the one that works for you.

Why use a similar photo cleaner on your Mac?

Your Mac’s Photos app may be great for organizing albums, but when it comes to finding and removing cloned images, it falls short. At this point, a third-party photo cleaner comes in.

A custom photo cleaner can scan your library for lookalikes, redundant images, and accidental repeats, helping you get your storage back. But photo cleaners go beyond just cleaning your gallery. Here’s what it can help you with:

  1. Free up disk space: Twin photos, especially HD ones, consume significant storage. Deleting them frees up gigs for new memories or essential files.
  2. Beyond Mac’s internal drive: Advanced cleaners can find duplicate files on external hard drives, keeping all connected storage free of unnecessary copies.
  3. Improve system performance: Excessive clutter can sometimes contribute to a slower-performing Mac. A tidy photo library contributes to overall system health.
  4. Streamline organization: By getting rid of visual noise, you can focus on your best shots and organize your collection more effectively.
  5. Declutter your photo gallery: A cleaner library means less scrolling through repeated images, making your albums faster and more enjoyable to browse.

All the tools covered in this guide run locally on your Mac, no cloud uploading required. They scan your files, surface duplicates and similar images, and let you choose what to delete. Most even offer a recovery feature just in case.

How we conducted the testing

To give you a clear, practical comparison, we tested each photo cleaner on a MacBook Air M2 running macOS 15, using a messy 112 GB photo library on Macintosh HD that reflects real-life use.

Our goal is to see which tool could accurately detect similar and duplicate photos, handle bulk comparisons without lag, and offer intuitive features like autoselection and preview. We paid special attention to speed, accuracy, and ease of use, so you’ll know exactly what to expect before you open the tool.

Option 1: Duplicate File Finder by Nektony

Duplicate File Finder icon Rating: ★★★★★ / 4.7
Price: Free for finding duplicate photos,
$17.99 yearly – the Pro mode with additional features
Operating system: macOS 10.13 or later

Duplicate File Finder by Nektony is a professional app you can use to declutter your Mac at every level: across your libraries, media, and folder structures.

Duplicate File Finder window

Unlike basic photo cleaners, this app goes beyond detecting duplicate images; it finds duplicate folders, similar pictures, identical music tracks, video records, and even lets you merge and compare folders or files with precision.

As soon as you launch the app, you can start scanning any folder or even an external drive for duplicate and similar images. The interface is intuitive and lets you switch easily between modes.

You can choose to review duplicates manually or take advantage of the Auto Select feature, which keeps one original and marks the rest for removal. It’s a huge time-saver if you’re dealing with thousands of files.

Before anything is deleted, you can review all selected items, and if you change your mind, the app also offers a file restoration option. If you’re looking for one robust tool to help you get rid of all the clutter from your gallery, this app is for you.

Highlights:

  • Scans internal and external drives
  • Finds similar photos, audio, and video files
  • Offers folder and file comparison
  • Lets you merge folders with duplicate-cleaning
  • Comes with a dedicated Statistics panel to track results
  • Allows recovery of deleted files
  • Works great in free and side-by-side mode

Pros:

Both duplicate and similar photos scanning

Auto-selection with extensive rule settings available

Finds and removes various file formats

Cons:

Some features are only available in the paid version

To enjoy pro features, looking through tutorials may be required

No similarity level functionality

Option 2: PhotoSweeper

Photo Sweeper icon Rating: ★★★★★ / 5
Price: $17.99 one-time purchase
Operating system: macOS 10.12 or later

PhotoSweeper, as the name suggests, is an app that allows you to find and sweep (remove) duplicate pictures from your Mac.

PhotoSweeper window

The app lets you pick the photo folders you want to scan, and then it scans those directories for any duplicate or similar instances. It then shows you potential duplicate photos in one-by-one, face-to-face or all-in-one mode, letting you quickly decide whether to keep or remove those items.

The app can also detect duplicates that have been edited in apps like Photoshop. This ensures you get to all the duplicates that exist in your storage. It also offers a matching slider, allowing you to decide how accurate you want to be in terms of finding similar or duplicate items.

It can then manually mark the photos to delete, or you can mark the ones you want to remove. This app is mainly for photographers as it offers several features for granular control over your media items.

Highlights:

  • Integration with Photos, Lightroom, and Capture One
  • Adjustable similarity detection
  • Detects edited and retouched versions
  • Keeps removed files safe in Trash or special albums
  • Offers side-by-side, one-by-one, and all-in-one preview modes

Pros:

Can find edited photos that are similar

Only paid option with a free trial

Matching-level slider

Cons:

Too advanced for ordinary users

Side-by-side photo preview

Deletion issues with large libraries

Option 3: Duplicate Photos Fixer Pro

Duplicate Photos Fixer Pro icon Rating: ★★★★☆ / 4.5
Price: $11.99 per year
Operating system: macOS, Windows, iOS, Android

Duplicate Photos Fixer Pro is designed to help users find both duplicate as well as similar photos from their Mac machines.

Duplicate Photos Fixer Pro window

This isn’t a generic file cleaner but rather a photo cleaner. With the app, you can scan the Photos app as well as external folders. You can also adjust the match level to find different types of similar photos.

You can manually select the photos to delete or have the app select those photos for you. The app supports all the major photo formats, including RAW. It can detect duplicates using time-based and geo-based tagging.

While the app runs fine, the interface feels a bit outdated. It certainly doesn’t have a modern interface that you might be used to seeing in other apps on your Mac.

It also only scans photos for duplicates; you can’t use it for other file types. An alternative would be a better choice if you want to remove video, audio, and other duplicates from your Mac.

Highlights:

  • Scans and removes both duplicate and similar-looking photos
  • Groups results so you can easily review and keep the best shots
  • Supports drag-and-drop or folder-based scanning
  • Integration with Google Drive without downloading

Pros:

Designed mainly for duplicate photo finding

Interface is outdated and less user-friendly

Supports RAW image format

Cons:

Doesn’t offer smart organizational features

Can find photos using time and geo tags

No trial option

Option 4: Cisdem Duplicate Finder

Cisdem Duplicate Finder icon Rating: ★★★★☆ / 3.9
Price: $19.99 per year
Operating system: macOS 10.11 or later

Cisdem Duplicate Finder works not just with images but with all kinds of files on your Mac. You can use this app to find and remove images, videos, audio, and other duplicate items from your machine. The app claims to use advanced scanning algorithms to detect duplicate instances of files on your storage.

Cisdem Duplicate Finder window

You can run a custom scan with the app to only find specific file types and sizes. The app offers an ignore list, the places on your disk you don’t want the app to scan. It supports external drives as well as network drives, if you use any.

In the context of finding similar images, the app tries to find images that are only slightly different from each other. You can then choose the ones to keep and the ones you want to delete. The app moves the deleted files to the Trash, allowing you to recover them. You can also get the app to delete your photos permanently.

Highlights:

  • Supports all major file types: photos, videos, music, documents, archives
  • Allows safe removal to Trash, custom folder, or permanent deletion
  • Groups results by file type, size, and count for easy review

Pros:

Supports many file formats

Offers advanced scanning algorithms

Modern user interface

Cons:

Scanning speed isn’t very fast

Trial version with limited options

Which app should you go for?

  • If you seek a versatile duplicate finder that handles similar photos and other file types with ease, speed, and precision.
  • Duplicate File Finder checks all the boxes.
  • If you’re a photographer and want more granular controls for finding similar items, PhotoSweeper will be a nice option for you.

Frequently asked questions

What’s the difference between duplicate and similar photos?

Duplicate photos are exact copies. Similar photos look alike but may differ slightly in angle, lighting, editing, or resolution (like burst shots or edits).

Does Mac have a built-in duplicate photo finder?

Not system-wide. Starting with macOS Ventura, the Photos app can detect exact duplicates within the Photos library, but it doesn’t work for similar images or files stored outside the app. For broader cleanup, third-party tools are necessary.

Can Apple Photos detect and delete duplicate images?

Apple Photos introduced limited duplicate detection in macOS Ventura and later, but only for exact matches, and only within the Photos library. It doesn’t scan your entire Mac or detect similar-looking images. For a full cleanup, third-party apps are more flexible.

Will deleting duplicate photos free up space on my Mac?

Absolutely. Especially with high-resolution images, duplicates can take up several gigabytes of space. Deleting them clears storage, reduces clutter, and can even boost your Mac’s overall performance, particularly if your drive was nearing capacity.
