8 Best Third-Party Duplicate Photo Finders for Windows

#1 Cisdem Duplicate Finder

#2 Duplicate Photos Fixer Pro
Compatibility: Windows 11, 10, 8.1, 8, and 7
Latest version: 1.3.1086.1158
My take: It's a dedicated app to handle duplicate and similar photos, especially the latter.
Duplicate Photos Fixer Pro can find duplicate and similar photos on your PC, Picasa library, Lightroom Classic, and Dropbox. If you enjoy photography or frequently edit photos, it is worth considering.
This app provides two comparison methods: Exact Match and Similar Match. Exact Match is for exact duplicates only. The scan results window lets you conveniently view the found duplicates. You can manually select unwanted duplicates to eliminate or just let the Auto Mark feature do it for you.
Similar Match finds similar images and lets you adjust the Matching Level, Bitmap Size, Time Interval, and GPS settings to make it identifies duplicates according to your needs. In my test, the app initially found fewer similar photos than Cisdem Duplicate Finder. After I lowered the Matching Level, it found more. Adjusting the Time Interval slider can also help identify photos taken in burst mode.
You can scan and preview photos for free, but the trial only allows you to remove 15 photos. Further removal requires the paid version.
Pros
- Offers flexible settings for detecting similar photos.
- Lets you exclude files and folders from scanning.
- Lets you easily view photos and their metadata (metadata can be valuable for professionals).
- Saves you from manually selecting duplicates to remove.
Cons
- Occasionally freezes when opening the app.
- A bit expensive.
- Only works with image files.
#3 Duplicate Photo Cleaner
Compatibility: Windows 11, 10, 8, 7, Vista, XP
Latest version: 7.24.0.28, release in December 2025
My take: A useful option for users who want to remove duplicate and similar images in Adobe Lightroom.
Duplicate Photo Cleaner scans very fast. In my test, it took just 12 seconds to scan my entire photo library. Like Duplicate Photos Fixer Pro, it scans image files only and automatically skips other file types.
It provides seven scan modes, allowing you to scan for duplicate photos (including RAW ones) in folders or Lightroom Classic on your computer. There’s an important scan setting called Similarity Threshold. If you set the threshold to less than 100%, this app will scan for both same and similar photos. A lower threshold will find more similar photos but also more false positives and vice versa. Therefore, you need to find a balance.
The duplicate photo finder provides four ways to view the results, and I recommend the Tree view and the MultiView view. Photo preview and metadata (like camera manufacturer and exposure time) are provided. There are several preset rules to help you effortlessly mass select unwanted copies for removal. Or, you can do it manually.
Pros
- Scans your PC for duplicate images and similar-looking ones.
- Includes a dedicated Lightroom Classic scan mode.
- Lets you exclude specific photos from scanning.
- Lets you export scan results to CSV, Excel, TXT or HTML.
- Offers multiple view modes.
- Helps you bulk select multiple photo duplicates for deletion.
- Offers a portable version.
Cons
- Only works with image files.
- A little costly.
#4 Duplicate Cleaner
Compatibility: Windows 11, 10, 8, 7
Latest version: 5.27, release in May 2026
My take: A highly configurable tool for finding and removing duplicate photos and other files on Windows.
Duplicate Cleaner is feature-rich and very configurable. If you know about tech or computer, you may find this app powerful. But, if you are not very compatible with tech, this app can feel overwhelming to you and is not the best choice. It finds duplicate photos, videos, music, documents, and other files in Regular Mode. For photo cleanup, you can switch to Image mode.
Duplicate Cleaner has two editions: Free and Pro. If you only need to delete exact duplicate photos, the Free edition is sufficient. It has fewer settings and options, making it easier to use. But similar-photo detection requires Pro.
The Image mode supports BMP, JPEG, GIF, PNG, PCX, TGA, ICO, HEIC, WEBP and more. It can find photos that are exactly the same, very similar, or loosely similar, based on your settings.
This duplicate photo cleaner offers several ways to view duplicates. And with dozens of options, its Selection Assistant feature can help you quickly select unwanted duplicates for deletion, though you may need to spend time exploring the various options available.
Pros
- Scan for duplicate pictures and other duplicate files.
- Find similar pictures too.
- Provide multiple scan modes and view modes to choose from.
- Make it easy to delete duplicates.
- Highly customizable
- Includes a wizard to guide you through the steps.
Cons
- Not beginner-friendly.
- Slow when using the Image mode.
#5 Ashisoft Duplicate Photo Finder
Compatibility: Windows 11, 10, 8.1, 8, and 7
Latest version: 1.7.0.1
My take: It's a simple but helpful app to help users deal with duplicate photos on PC.
If you are new to duplicate photo finder software and only need a simple tool to help you those duplicates in your photo collections, Ashisoft Duplicate Photo Finder can be your choice due to its simple design and beginner-friendly interface.
Its scanning speed was a little slow in my test, taking about one minute to scan my entire photo library. And it doesn’t do a good job of identifying similar photos. It offers three levels of similar image detection, from very similar to loosely similar. But none returned relatively satisfying results in my tests.
There are two view modes and a preview pane to help you easily review duplicate photos that have been found. And clicking a photo will display both preview and basic information like name and size. You can use the Auto Mark feature to quickly select all duplicates and then delete them with a single click.
Pros
- Finds duplicate and similar photos.
- Lets you exclude specific folders.
- Offers side-by-side view along with a preview pane.
- Makes it easily to bulk delete duplicates.
- Straightforward and beginner-friendly interface.
Cons
- The Look for Similar Pictures feature was not very effective in my tests.
#6 Awesome Duplicate Photo Finder
Compatibility: Windows 11, 10, 8, 7, Vista, 2003, XP, 2000
Latest version: 1.2.1, released in September 2023
My take: It’s a free duplicate photo finder with reliable performance and a simple interface.
Are you in search of a good app to find and delete duplicate photos on Windows 10 or 11 for free? Check out Awesome Duplicate Photo Finder.
Despite being freeware, it has all the makings of a good basic duplicate picture finder. In addition to four major image formats, it supports CR2, a Canon RAW format.
This free app excels at finding duplicate images and can also detect similar images. In testing, it successfully found compressed or recolored photos but failed to find other similar photos. Thanks to the preview feature, you can easily preview and compare found photos side by side.
But there can be a big drawback. You have to manually select undesired duplicates for removal one by one, since there is no way to automate the process or mass select duplicates. So this can make the cleanup process tedious and time-consuming.
Pros
- Capable of identifying identical and certain similar photos.
- Lets you conveniently preview images.
- Easy to use with a simple interface.
- Completely free to use.
- Compatible with almost all Windows versions.
Cons
- Time-consuming removal process since you have to select files to remove one by one.
#7 Visual Similarity Duplicate Image Finder
Compatibility: Windows 11, 10, 8.1, 8, 7, and Vista
Latest version: 9.6.0.1
My take: It’s a feature-rich Windows duplicate photo finder that might be for more advanced users.
Visual Similarity Duplicate Image Finder is a feature-rich and highly customizable duplicate photo finder for Windows 11, 10, and earlier. It can help users find both duplicate and similar images. However, the interface may be confusing for beginners.
The app scans folders and Lightroom Classic for duplicate or similar photos, depending on your settings. There are four scan methods. We recommend the first two: Visual Compare and 100% Identical Files (Fast). If you only want to search for exactly identical photos, choose the 100% Identical Files (Fast) method.
With Visual Compare, you can find exactly identical photos, very similar photos, and other similar photos. You can adjust the Similarity level, which is 95% by default.
This app has a sophisticated feature to help users select duplicate photos for elimination. For example, in each group of duplicates, you can set it to select the smaller or newer one(s) to delete, or specify an image format (such as .jpg).
There is a Standard edition (enough for most personal users), a Pro edition and a Corporate edition.
Pros
- Scan for photos that are the same or similar
- Offer multiple scan methods to meet different needs
- Allow you to compare two folders for duplicate photos
- Support Lightroom Classic
- Support various RAW image formats
- Offer a side-by-side preview feature
- Highly configurable
Cons
- Potentially confusing interface
- Some scan methods are slow
- Sometimes can’t be installed successfully
#8 Easy Duplicate Finder
Compatibility: Windows 11, 10, 8.1, 8, 7, XP
Latest version: 7.34.0.72, released in June 2025
My take: It’s a pretty easy-to-use app to look for and clear duplicate photos on a PC.
Thanks to the straightforward and easy-to-navigate interface, this app is indeed easy to use, even for beginners.
The app offers several scan modes, with the default mode being the best for scanning for duplicate photos on your computer. By default, the scan searches for all duplicate files. But you can set it to focus solely on images and skip other file types.
When the scan is complete, you will be presented with the results window, which neatly displays the found duplicates. There’s a built-in preview feature, which is hidden by default. You can make it visible with a simple click.
This duplicate photo remover has an efficient selection feature, which makes the removal process quick and efficient. It offers three sets of preset selection rules, each set containing several rules. In most cases, the Select all duplicates rule is sufficient. However, if you have specific preferences for which files to keep or delete, you can choose a rule that best meets your needs.
Pros
- Search for duplicate photos and other duplicates.
- Provide multiple scan modes.
- Display search results in a neat and easy-to-view way.
- Help you easily clean up unwanted duplicates at once.
- Very easy to use
Cons
- Preview feature needs improvement.
The Built-in Duplicate Photo Finder in Windows: Is It Good Enough for You?
Note
If the app you see on your computer is called Photos Legacy, get Microsoft Photos from the Microsoft Store, since duplicate detection is not available in the legacy version.
Pros
- Included in Windows 10 and 11
- Capable of detecting duplicate photos with the same file name within and across folders added to Microsoft Photos
- Capable of handling a large photo collection
Cons
- Can’t find same photos that have different file names
- Can’t simplify removal of duplicates, with you having to select unwanted duplicates for removal one by one
My Take
This built-in tool can be the best choice if you only want to see if there are any duplicates in your photo collection, or if there are only several duplicates to remove. It's not useful enough if you want to effectively find all identical photos, including those with different names, or if there are many duplicates.

Microsoft Photos could be helpful, but I have so many duplicates to get rid of. I guess I'll try the Cisdem app.

I have thousands of photos on my computer and there’re too many duplicates. Now I got back over 3 GB of space after using the first software you recommended. Thanks so much!!
