• Easy search of photos
Just drag and drop folders from your Mac to allow PhotoSweeper to find all photos inside. Add more photos from your Photos, iPhoto, Aperture, Capture One or Lightroom library via the Media Browser window.

• Flexible comparison settings
Powerful multi-settings to easily find duplicates, similar photos, series of shots. The app finds duplicate photos, even those edited in external programs such Photoshop, regardless of image size or format.

• “Side to Side” comparison
Find duplicates between two groups of photos while ignoring those inside each group. It allow you to compare the contents of two folders with each other or find similar photos to a single image.

• High speed and quality
PhotoSweeper was developed as a tool for extremely fast comparison of a huge number of photos. Cutting-edge technologies and unique algorithms make searching duplicates incredibly fast and gives excellent comparison results.

• Efficiency
You can regroup the results without re-comparing photos by changing matching level with a slider. Using caches makes the next comparison much faster.

PhotoSweeper also serves as an up-to-date photo browser with a built-in search of photos by metadata, Quick Look preview, the "Info" panel with a detailed photo description, including histogram and image metadata (EXIF, IPTC etc.).

Just absolutely brilliant

I had a specific problem that I needed solved: Identical duplicates with unique metadata that completely fools any less sophisticated programs. I had added most of my paper photos to my library by scanning using an HP feeder scanner for standard size photos. Problem #1: some packs had been ordered with duplicate copies from CVS. After scanning each duplicate has its own metadata and slightly different digital characteristics. That was 2010. Then in 2017 I did it again (dont ask why). Now I was at 144,000 photos with up to 4 copies each with unique metadata. Crisis! First run with PhotoSweeper on basic settings eliminated 40,000 exact duplicates. Then using the advanced features that search for identical color balance in the photo. That took out another 10,000. The program nearly always defaulted to the best shot (highest megapixels, and some other AI algorithms). I checked 100 of the duplicates at random and only found 1 photo where I would have kept a different image. On my 2017 iMac with 64gb ram the first run took nearly 10 hours running in the background, but I was able to continue WFH while it did its thing. The coder of this program should receive a nobel prize (maybe the noble prize too)!

Wow! Best clean up tool for photo libraries I’ve ever come across

This tool does a great job of finding duplicates, not just exact duplicates, but photos that have been rotated, resized, or are even just very similar. It also has a great set of default rules for figuring out which image to keep automatically, which can save hours. But what most impressed me about this app, is how fast it is! I have two very large libraries of photos, about 45K in iCloud Photo Library, and another 60K or so in Lightroom. Any operation that involves scanning so many photos usually can bring either of those apps to a crawl, sometimes waiting days for an operation to complete (even when the entire library is on SSD). But PhotoSweeper just rips through those thousands of files so fast, it’s unreal. I think Apple and Adobe could maybe learn a few things from this software, I was totally not expecting this kind of performance from a third party app.

Used to be great (updated)

Turns out a simple restart fixed my issues with this app! Glad to see it still works as I remembered, and I even found some new features while troubleshooting. Worth the money!

Original review:
I have been using this app for a long time now to sort out photos I've downloaded multiple times or copied by accident in both Apple Photos and Finder. It worked wonderfully, until I needed to use it again recently. I assume it has to do with my update to Catalina, but now whenever I mark items for deletion in Finder, it corrupts the files instead of simply moving them to the trash. Since there's no easy way to determine what files are corrupted except for (trying to) open them, I am left deleting each file one by one in a process that takes considerably longer than manually sorting them. Please update to support Catalina!
