Apple’s AirDrop is a hugely convenient feature for transferring photos, videos, documents, and other files between the company’s devices, including iPhones, iPads, and Macs. You can easily send something to a friend — or use AirDrop as a handy way of transferring files between your own products.

What’s great about AirDrop is its simplicity. Instead of trying to clumsily share files using Dropbox, Google Drive, or some other cloud storage, it’s an immediate transfer from one device to another that (in most cases) takes only seconds.

With AirDrop, Apple creates a peer-to-peer Wi-Fi connection between the two devices in an AirDrop exchange. These devices communicate directly and aren’t required to be using the same internet connection.

Some people get a kick out of sending memes — or more unwelcome, lewd content — to complete strangers with AirDrop. Thankfully, Apple gives you a few different options for limiting how easily you can be reached with the feature.

AirDrop settings are easily accessible from Control Center.
