Choose a photo library

Here's how to open one of the multiple photo libraries that you might have on your Mac or on a connected external drive:

1. Press and hold the Option key as you open the Photos app.
2. Select the library that you want to open, then click Choose Library.

Photos uses this library until you open a different one using the same steps.

Export photos and videos from the source library

Open the source library, then decide whether you want to export your files as unmodified originals or edited versions:

Edited versions retain their edits when you import them. The advantage is that you don't have to recreate any edits; however, these files become the destination library's originals. This means that you can't revert to their earliest pre-import version.

Unmodified originals don't show any edits that you made when they were in the source library. This gives you flexibility for later editing, but recreating your edits might take substantial work.

How to export edited versions

1. In the Photos app, select the photos and videos that you want to export. To select multiple items, press and hold the Command key while you click. To select a group of items in order, click the first one, then press and hold the Shift key while you click the last one. This selects all of the items between the two that you clicked.
2. Choose File > Export > Export [number].
   
3. An export dialog appears.
   
   • In the Photos section, set Photo Kind to JPEG, TIFF, or PNG. JPEG recompresses your photos, which may result in smaller file sizes. TIFF and PNG files are higher fidelity and may result in larger file sizes.
   • In the Videos section, choose a Movie Quality setting. This section appears only if your selected items include videos.
   • In the Info section, select the checkboxes if you want to preserve metadata and location data in the exported files.
   • In the File Naming section, set File Name to Use File Name and set Subfolder Format to either Moment Name or None. Moment Name creates a subfolder for each Moment that's represented in your selected items. This is useful if you'd like to create an Album in the destination library for each Moment. The None option exports all of the files directly into the destination folder.
     
4. Click Export. A Finder dialog appears.
   
5. Navigate to the location where you want to save the files, such as the Desktop or an external drive. Click New Folder if you create a new folder for your exported items.
6. Click Export.

   • Leave the File Name setting on Use File Name.
   • Next to Subfolder Format, choose Moment Name or None. Moment Name creates a subfolder for each Moment that's represented in your selected items.

4. Click Export. A Finder dialog appears.
