PhotoSweeper Lite (a lightweight version of PhotoSweeper) helps you to get rid of duplicate photos. It works with photos from Apple Photos, iPhoto, Aperture, Adobe Lightroom and Capture One libraries, as well as photos from your hard drives and external storages. It allows you to find and group photos that have identical or very similar content, regardless of image names.

DUPLICATE photos - absolutely identical photos, created by reserve copying or using multiple photo libraries etc. If you have several Macs, external hard drives, or just multiple copies of the same photo collection, and want to remove duplicates, this application is for you.

SIMILAR photos - photos that look identical to the human eye, but are different for a computer, usually created by multi-shot capturing of the same scene, or by editing with special software, like Adobe Photoshop, Pixelmator etc. PhotoSweeper Lite DOES NOT detect this kind of photos as duplicates, but the FULL version of PhotoSweeper DOES the trick.

With PhotoSweeper Lite you get:
• Support for Photos, iPhoto, Aperture, Lightroom and Capture One libraries.
• Beautifully designed and easy-to-use interface: great photo browsing, reviewing results in different modes, automatically marking photos etc.
• Extremely fast workflow: based on state-of-the-art technologies and optimized for photo comparison.

This is the LITE version. The FULL version is named "PhotoSweeper" and it:
• Finds SIMILAR photos providing extra comparison settings. Photos are compared regardless of their sizes or formats and are grouped by similarity. It allows you to find even edited photos and series of shots.
• Moves or copies photos you want to keep with or without bulk renaming.

PhotoSweeper Lite to the Rescue… and rescue it did!


iPhoto… I loved ye…. but…. when Photos came out… Apple did a dirty trick… instead of migrating your iPhoto Library… Apple decided to do some hybrid nonsense… and make your computer use Photos for new pics…. and doing some kind of appending onto the previous iPhoto library. Not good, not good. Very inefficient use of disk space…. and it causes problems when you have to restore your system.

Add to it…the way that Apple is always changing how crap synchs up between items in the Apple EcoSystem… and Voila… you have a hot mess….

See, I have an iMac, an X-serve, a Mac-Mini, a Macbook Air, and a MacBook Pro. Add to it… an iPod Touch, and iPhone, and iPad, and an Apple Watch… and you can pretty much determine… that I don’t have any idea whatsoever…. I have in my multiple libararies. LOL.

I am on my iMac right now… and it had different a different iPhoto library than my others…it is the main photo editing machine. I tried this program here first.

I added all my files… tweaked the settings…. and read the manual (on-line). I removed 1447 photos saving 1.89 GB of disk space. I am not purging dupes for the disk space, just to make sure that I am not carrying on tons of extra files.

I was surprised at the 1447 files… OMG…how did that happen?

Well, what I did like… was when it went to purge dupes… it marked the ones to keep and the ones to purge. It did a great job. I had used Perfectly Clear (iPhone) to enhance some pics… and the program picked the best ones…and decided to purge the crappy ones. Also, if there was one that was bigger… i.e. had more detail… it kept that one … as long as the pic quality was the same.

I find this a great program… great cost… I did not need to find the similar ones… just rid me of dupes.

I give this 5 stars…. but just a word of caution… please review all the dupes that it shows…. to make sure that you are purging the correct files. It ended up dumping them in photos in a folder to delete… I just might back them up on a network drive… just in case I mucked something up. Kudos to the programmers!

The app is great and the support is Incredible!!!


Not being very computer saavy I found that I had somehow duplicated (over and over) my photo downloads and before I knew it, I had three times as many photo’s as I should have. I spoke to an Apple Genius on the best way to clean my iMac and they suggested this app. Sure enough, it did a fabulous job and was easy enough that I was able to use it without assistance. I did however find that I had “touched” some photo’s and the app did not remove photo’s that were no longer exactly identical. I used the HELP feature, connected with a Super Helpful gentleman who not only was quick to respond to my emails, but he also sent pictures and step by step instructions. Loved the app and the support so much, I purchased the Full Version and have told everyone I know with similar issues to do the same. Was not expensive and I’ve never regretted the purchase.
