AirDrop is a feature available on Apple devices that allows users to share files wirelessly with nearby devices. It uses Bluetooth and Wi-Fi to create a secure connection, enabling the transfer of photos, documents, and other data without needing an internet connection. To use AirDrop, both the sender and receiver must have the feature enabled on their devices. Users can choose to share files with everyone nearby or limit sharing to their contacts. This makes it a convenient option for quickly sending information between iPhones, iPads, and Macs.
