What is iCloud?
Photos
iCloud Photos is likely to be the feature you use the most — it stores all your images and videos in the cloud, so it doesn’t matter what device you’re using when you want to look at or edit your photos or movies — so the photos we take on our iPhone are editable on our Mac and viewable on our Apple TV and Apple Watch. And because they’re stored in iCloud they don’t need tons of room on your devices.
