iCloud storage management overview

If your iCloud storage runs low, there are several ways you can increase your available space. You can reduce the size of your iOS device backups or remove entire backups from iCloud, reduce your Camera Roll backup, choose which documents to store in iCloud and remove email messages.

Films and trailers in iMovie Theater may use larger amounts of iCloud storage than other documents. To learn more about managing films and trailers stored in iCloud, see the iMovie Help topic about iMovie Theater on iPhone, iPad, or Mac.
