The ultimate toolbox for Photos on your Mac
PowerPhotos works with the built-in Photos app on your Mac, providing an array of tools to help you get your photo collection in order.
Create and manage multiple libraries
Instead of being limited to putting all your photos in a single library, PowerPhotos can work with multiple Photos libraries, giving you many more options for how to organize your ever growing photo collection.
Splitting your photos between multiple libraries helps Photos open more quickly, lets you archive older photos, store some of your collection on an external hard drive, and reduce storage space used by iCloud Photo Library.
Copy photos and their metadata
You can split your library by copying albums and photos with a simple drag and drop. PowerPhotos will take care of copying the photos and retaining their metadata, including keywords, descriptions, titles, dates, and favorite status. Read more about what PowerPhotos can copy.
Merge Photos libraries
Got a whole bunch of libraries you want to consolidate into one? PowerPhotos lets you merge your libraries together while weeding out duplicate photos in the process. You will be shown a preview of what your merged library will look like before any modifications are done, to ensure your merged library looks how you want.
Find duplicate photos
Photo Library
It's easy to have multiple copies of the same photo creep into your photo collection over time. Use PowerPhotos to find duplicate photos in one or more libraries, view them side by side, and separate them into albums where you can easily delete them from your library.

Use PowerPhotos' image browser to quickly view your photos without having to open Photos itself. View detailed photo information using List View, and search for photos across all your libraries at once.
