AirDrop for Windows: what actually works

There is no AirDrop on Windows, and there will not be

AirDrop is Apple's protocol, on Apple's hardware, using a combination of Bluetooth for discovery and a direct Wi-Fi link for the transfer. It is not licensed to anyone and there is no compatible implementation.

Everything marketed as "AirDrop for Windows" is a different thing with a similar goal. Worth knowing which is which, because they fail in different ways.

Quick Share (formerly Nearby Share)

Google's equivalent, and the closest thing to AirDrop outside Apple. Android to Android, Android to Windows, and Windows to Android via an app from Google.

Works well for phone-to-PC in the same room. Fast, no account needed for device-to-device, no size limit worth worrying about.

Does not help if either end is an iPhone or a Mac, which is usually the case that sent you looking.

Phone Link / Link to Windows

Microsoft's phone integration. Good at notifications, messages and photos from a paired Android phone. Not a general file transfer tool, and the iPhone support is deliberately limited by what iOS permits.

Cloud storage

Dropbox, Drive, OneDrive, WeTransfer. Reliable and universal, and the trade is explicit: the file goes up to somebody's server, sits there, and comes down again.

That means the transfer takes as long as your upload speed allows, which on a domestic connection is usually far slower than the download, and the file is on a third party's disk afterwards, for however long their retention says.

For a 2 GB video on a 20 Mbit upload, that is about fifteen minutes up before anything starts coming down.

Email

Still the most common answer and the worst one. Attachment limits are 25 MB on Gmail and similar elsewhere, the file is base64-encoded so it takes about 33% more space than it should, and it ends up in two mailboxes forever.

The browser route

Two browsers can connect directly to each other using WebRTC: the same technology behind video calls. One machine opens a page and gets a code, the other enters it, and the file goes between them.

What it gives you: no account, no app, no install, no size limit, and on the same network, local-network speed rather than upload speed. Any two devices with a modern browser, which includes the iPhone-to-Windows case that nothing else covers.

What it needs: both devices online at the same time, since there is no server holding the file. This is a genuine difference from cloud storage, it is a handover rather than a drop-off.

Where it fails: networks that block peer-to-peer traffic. Corporate wifi, some university networks, and a lot of hotels. The two browsers cannot find a route to each other, and no amount of retrying invents one. The usual fix is to put both devices on the same network (a phone hotspot is enough) or to use a relay, which forwards the packets through a server that both sides can reach.

Picking one

• Both Apple: AirDrop. Nothing else is as good.
• Both Android, or Android and Windows: Quick Share.
• Mixed, same room, same network: a browser transfer. It is the only

option that does not care what the two devices are.

• Recipient not online now: cloud storage. A direct transfer needs both

ends present.

• Very large file, same network: a browser transfer, because it moves at

local speed rather than upload speed.

• Sensitive file: a direct transfer, because there is no third copy.

On the same network is the point

The thing that makes AirDrop feel instant is that the data never leaves the room. Sending a 5 GB video via the cloud means pushing it to a datacentre and pulling it back to a machine two feet away.

Any transfer that goes directly between two devices on the same network gets that same advantage, whatever the technology. Where a direct route exists, use it.
