There is only one copy of the image file in my library, so this duplicate does not need much additional storage. I tested again and imported a photo twice: Photo Sweeper can recognizes different versions of the same photos, because it compares histograms and pixel maps, while power Photos will only compare the file attributes, not the contents of the images.īTW, if you import the same image file twice, and Photos warns you about the duplicate, but you insist and import it nevertheless, the image file will only be stored once in the Masters folder of your library. On Mac, since you might want to find and clean not only the duplicate photos, but also other duplicate music, documents or things like that, I would recommend you to get MacPaw Gemini 2 as your general duplicates cleaner, it’s the most cost-effective duplicate finder and similar photo remover for Mac.
What kind of duplicates do you have I your library?ĭid you import the same image file twice? Or do you have several edited versions of the same photo or versions in different sizes? Photos will recognize duplicates when you try to import them and warn you, if it are identical copies of the same image file, but it does not treat edited versions of the same image as duplicates or downsized, smaller files.
