Set up and use iCloud Photos
iCloud Photos automatically keeps every photo and video you take in iCloud, so you can access your library from any device, anytime you want. Any changes you make to your collection on one device change on your other devices too. Your photos and videos are organized into Years, Months, Days, and All Photos. And all of your Memories and People are updated everywhere. That way you can quickly find the moment, family member, or friend you’re looking for.
Your photos and videos are stored in iCloud in their original formats at full resolution. This includes HEIF, JPEG, RAW, PNG, GIF, TIFF, HEVC, and MP4 as well as special formats you capture with your iPhone or iPad, like slo-mo, time-lapse, 4K videos, and Live Photos. The photos and videos you capture with these devices are in HEIF and HEVC format. Depending on your internet speed, the time it takes for you to see your photos and videos on all of your devices and iCloud.com might vary.
