• You have photos scattered on external hard drives and local disks, in Apple Photos, iPhoto, Aperture, Lightroom or Capture One libraries.
• You have a mess in your photo collection or just want to free disk space by removing junk photos.


• 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, Lightroom or Capture One 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.

• 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.

Mark photos you want to get rid of manually, or use the "Auto Mark" feature to mark duplicates automatically based on the list of rules you can adjust to your needs in the Preferences.

• Comfortable viewing results
PhotoSweeper provides 3 modes for reviewing results: “One by One”, ”Face-to-Face" - one or two large photos with an opportunity to mark a photo with just a click, “All in One“ - all groups of duplicates in one list.

• Great photo browsing
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.).

Only App. in this App store for finding Duplicates

Bought all the other app that find duplicate photos and this is the only one that has any benefits. It found many duplicates and did what was advertised. Other Apps. I bought couldnt even load up large libraies of photos, this app could. That being said, I feel that the search options for duplicate photos should have more options (granted this app has more than any others out there that I just wasted my money on). I noticed it has been missing many files that are the same pic just scanned in differnet formats. Trying to find a way for the app to see the duplicates I contacted there support and they got back to me within a day (that is saying more than the other apps. too that have not responded —still). To find them I used the “Series of shots” method with 0 seconds (PhotoSweeper uses milliseconds so results will be precise). And I used the “Similar Photos” method with 0 seconds and set the Matching Level to lower value. Found many more but, this took hours and hours. Over all, great for what out there these days, just think it could be even better!

Really Struggles with Large Collections

This is a promising and robust problem, but it’s flawed. It sports an enormous number of options, as compared to some other duplicate-photo finders. That said, it hasn’t really worked for me. After numerous passes, even with extremely liberarlly settings applied, PhotoSweeper consistently misses duplicate photos that are clearly all-but-exact replicas of one another. I’ve given this a few months of use now, and I’m fairly certain I’m not missing anything; I understand the settings. It makes no difference, as I’m consistently finding duplicates by going through my files myself, which uses a lot of time. This essentially defeats the purpose of the software; if I have to check its work, all the time, then it’s not truly working at all.

The one thing it does exceptionally well is find *similar* photos—e.g., two photos snapped within moments of each other which are almost alike but which aren’t truly duplicates. I use this program for that. For duplicates, I use Duplicate Detective, which does its job perfectly.

This may just be me. I uses Photos to organize my collection. I have tens of thousands of images. Perhaps others will have better luck in other systems.

The Undisputed Champ In Finding Duplicate Photos

I had a library of over 19,000 photos which had thousands of duplicates. I tried several apps before PhotoSweeper, including Duplicate File Cleaner, Duplicate Detective, and Photos Duplicate Cleaner. None of them found more than a handful of duplicates--and some found no duplicates--even after tweaking the settings to be as lenient as possible. I contacted one of those developers and they responded to say that the sample duplicates I sent them were not actually duplicates! (They definitely were duplicates, not retouched or modified in any way.) Then I found PhotoSweeper, and despite it being more expensive than the others, and feeling a bit dubious at that point, I decided to give it a shot. So glad I did. It worked amazingly well, finding all the duplicates (over 9000) and auto-marking them for deletion, in a matter of minutes. Thanks devs for such an exceptional app!
