Description
Use PixCompare to search for duplicates or similar pictures in a large collection of picture files, folders or the Photos app.
PixCompare Features
- Find duplicate and similar pictures in a folder full of pictures
- Find duplicates and similar pictures in Photos
- Move pictures directly to the trash folder
- Move pictures to a different folder
- Display results as groups of similar pictures or as a list of similar pairs of pictures
- Compare one picture to a folder of other pictures
- Use macOS built-in Quicklook to display pictures in full size
- Works best on photographic pictures, file formats supported: JPEG, PNG, GIF, TIF, HEIC, and most RAW files.
- Search through up to 100,000 pictures (about 3000 per GB available RAM)
- Display up to 5,000 results
PixCompare can match two pictures even when:
- one of them is grayscale
- they don’t have the same size / aspect ratio
- the contrast / intensity is different
- they have a different pixel-depth
- and when one of them is blurred or rotated
Display results in two different result modes:
- Grouped Mode: Result pictures are displayed in groups of similar pictures.
- List Mode: Pairs of similar pictures are displayed in a list. The list is sorted by similarity score, i.e. the most similar pairs are at the top of the list.

Ratings and Reviews
Great App
In approximately 97 to 98% of cases, the app is very efficient and precise, correctly detecting identical or different from each other only in terms of details such as slightly different resolution or color depth duplicates, when its Similarity threshold is left set at the default 80%. However, there is approximately from 2 to 3% of cases when PixCompare puts nearly identical photos into different groups in Grouped view, not juxtaposing them all together, so that even if you remove some of those nearly identical photos from one group, the same such photos are not compared and may be overlooked and mistakenly left in other group. All in all, then, the app is great, and would be perfect if it were possible to improve it by making it compare to one another all of the nearly identical photos fitting under the Similarity threshold set, and not leaving out some of such photos
For Me The Price Is Worth The Experience
True, it doesn't work very well. Frankly, I'd be willing to pay 10 times the price if the app was brought up to useable standards.
I applaud the developer for this creation... The description is clear regarding best performance for photos.
My wife had a box of over 100 old 1900s B&W negatives from her ancestors gold mining and other businesse In Silverton, Ophir, and Ouray, Colorado. I found a guy who charged a reasonable price to create digital negatives and images. I ran the folder through this app and it listed many duplicates.
Luckily, I was cautious and looked at the image types being compared. We were provided with RAW files, Tiff files, and JPG files, to allow the best choices for my wife's projects.
I ran a myriad of other image files through the program and less than 1% actually matched.
Actually, just viewing the images allowed me to choose many to simply delete.
Great Accuracy - Needs More Speed
I’ve used previous versions of this app, so I’m thrilled to see it back in the App Store with an updated version.
It has great accuracy, certainly at least as good as PhotoSweeper. My main complaint is that it’s not very fast. Right now, I’m running on a multi-core machine, but maybe one core is really working as it loads files. PhotoSweeper clearly maxes out the CPU and gets results *much* faster.
The matching algorithm is clearly more accurate than PhotoSweeper, but I’d love to see the two programs merge - the UI and speed of PhotoSweeper and the matching code from PixCompare. In the meantime, buy both - each will find duplicates the other one misses.
