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

Jason L Douglas

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.

PhotoSweeper is incredible!


My photo library became corrupted by backing it up with defective backup software which created 68,000 duplicates with only 13,000 originals. I had 70 duplicates of one photo! I ran side-by-side comparisons and used ‘exact duplicate’ to compare my photos. PhotoSweeper went through all photos and gave me a listing of each photo and its duplicates to review. One photo was marked for keeping while all the duplicates were marked for possible deletion (only if you choose automark). I looked at the duplicates and the jpeg number was the exact same jpeg for all duplicates. I then chose to move the photos to PhotoSweeper trash. So, yes, PhotoSweeper did its job. I could never have gone through all 79,000 photos and found 68,000 duplicates and kept my sanity. And all this for $9.99. Incredible app and incredible support. Emailed support and received an answer in 10 minutes. Highly recommended!

It worked well … but not immediately


This app, to my mind, is saved by outstanding email support. It clearly works but it took me around 2 days and a dozen emails to get it to do so. That said, responses were super quick and they didn’t give up. My situation cannot have been unusual (macbook using a single directory for mac photos) so it was disappointing that the app refused to work “out of the box”. Once it worked (the solution was to rotate all my 10,000 photos so that they were regenerated, then rotate them back) the experience was a smooth and professional one removing some 4000 duplicate photos. A word of warning (and this probably applies to any app of this type) is that if photos are in albums many of them will lose their album designation and have to be replaced manually - I guess you can’t control which of the duplicates are erased by defining the album.
