iCloud Photo Library was designed to keep all your personal photos and videos safe, synced, and available on all of your devices.
That sounds simple, but the idea of a hybrid library, where our content seamlessly spans the internet and our iPhones, iPads, and Macs — where the line between online and offline blurs — can be tough to grasp.
For years many of us have manually, meticulously managed our photos and videos — transferring them from our camera and phones over cables and local networks, organizing them into folders, backing them up to drives, and hoping beyond hope each time that nothing would be damaged or lost.
Various online services have popped up to help, but often they're just as manual or they're attached to social networks whose views on privacy might not match our own.
iCloud Photo Library aims to solve all of that, by keeping all of our pictures and videos available, and doing it all automatically.
