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
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.

Browse and search
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.

Migrate your iPhoto/Aperture libraries
If you have a lot of existing iPhoto or Aperture libraries that you want to migrate over to Photos, PowerPhotos will help automate your migrations so you don’t have to spend time babysitting this lengthy process.

→ New features:

• Improved iCloud Photos support: If you use iCloud Photos, PowerPhotos 1.x was only able to see photos in your library that had already been downloaded to your local hard drive. For users with the “Optimize Mac Storage” option enabled, this could mean a significant portion of your iCloud library would not be visible to PowerPhotos. In PowerPhotos 2.0, it can now see and work with any photos in your iCloud photo library, and will automatically download any photos from iCloud as needed.
• Advanced exporting: Photos has an export command, but it is fairly limited in what it can provide. PowerPhotos 2.0 has a new, more fully featured export function with options such as
◦ Export as a flat folder or as a folder hierarchy in the Finder that mimics your album hierarchy
◦ Export unmodified photos, or as JPG, PNG, HEIF, or TIFF of different sizes
◦ Include captions, dates, keywords, and titles in EXIF metadata
◦ Retain or strip location metadata
◦ Optionally include videos from Live Photos and all photos from a burst
◦ Set Finder creation/modification dates to the photo’s EXIF date
◦ Video export support as H.264 or H.265
• Global menu bar item: Get fast access to your libraries via a global item in your menu bar even when PowerPhotos itself isn’t running.
• Library groups: For those with lots of libraries, you can now organize your libraries into groups in the PowerPhotos sidebar.
• Multiple windows: You can now open each library in a separate window in PowerPhotos, allowing for easier comparison between libraries, and dragging and dropping photos/albums between libraries.
• New duplicate search engine: PowerPhotos 2.0 uses a new duplicate comparison algorithm that can find more duplicate photos which are not quite 100% identical, such as scaled down copies of photos, photos that have been resaved in a different format or with different compression, and even photos with minor edits applied to them.
• Faster library loading: PowerPhotos 2.0 has rewritten a bunch of its internals to load your library much faster than PowerPhotos 1.0.
• Improved AppleScript support: New support for copying albums or photos between libraries, merging libraries, and exporting photos/albums from a library.

Supported Operation System
• macOS 11.0 or later
• Apple Silicon or Intel Core processor
