iCloud Photo Library
The ins and outs of the iCloud service you’ll use most
The iCloud Photo Library automatically copies any photos or videos you take on your devices and stores them in iCloud. You can then access them on your other Apple devices or share them with others. It supports the most common photo and video formats, including Apple’s favored HEIF (High Efficiency Image Format) and HEVC (High Efficiency Video Codec) formats and the standard JPEG, RAW, PNG, TIFF, MP4, and GIFs used by most image apps. It integrates seamlessly with your Photos app (and the data it syncs includes your People album, which is the one that uses image recognition to recognize people in your photos). You can also access your library from any web browser via iCloud.com.
