Web AirDrop alternatives — no app, any two devices
How five approaches actually work, what each one limits, and when to pick which
Drop your files here to start right now Start transferring now
AirDrop is an Apple-only feature; Windows and Android can't use it. Cross-platform approaches fall into three families: browser-based peer-to-peer transfer you just open (Snapdrop, PairDrop, and this site), local-network tools you install on every device (LocalSend), and upload-then-share services that put the whole file on a server first (WeTransfer and similar). The differences come down to four things: whether anything needs installing, whether it crosses networks, whether files pass through a server, and whether the result is verified.
The install-something family is usually the fastest, because it stays on the local network with no internet round trip. The price is that every participating device needs the app first. Fine for your own phone and laptop; friction the moment you're sending to someone else's device, since few people will install software to receive one file.
The upload-then-link family lets the two sides be online at different times — but the file sits on someone else's server for a while, and the free caps and expiry dates exist because that storage and bandwidth cost them money. Browser-to-browser transfer has no such cost, so it has none of those caps; the trade-off is that both sides have to be on the page at the same time.
All five, side by side
| Option | Install an app? | Across networks? | Through a server? | Integrity check | Status |
|---|---|---|---|---|---|
| AirDrop | Built into the OS | Nearby devices only | Not through a server | Not documented publicly | Apple devices only |
| Snapdrop | Nothing to install | Same network required | Relayed by its server | Not documented publicly | Domain changed hands |
| PairDrop | Nothing to install | Works across networks | Not through a server | Not documented publicly | Actively maintained |
| LocalSend | On every device | Same network required | Not through a server | Not documented publicly | Actively maintained |
| WeTransfer | Nothing to install | Works across networks | Uploaded first, then downloaded | Not documented publicly | Free tier has a cap |
| TutuDrive Send | Nothing to install | Works across networks | Not through a server | sha-256 on every file | This site |

Common questions
How does a "web AirDrop" actually work?
Browsers ship a capability called WebRTC, originally built for video calls, that can open a direct channel between two browsers. The server does exactly one job: helping the two sides exchange the information they need to find each other. After that the file travels on that channel and no longer touches the server. That is also why these tools need no app — the capability is already in the browser.
Can it work when the two devices aren't on the same Wi-Fi?
Depends on the family. Tools like LocalSend that discover devices on the local network can't: if the phone is on mobile data and the laptop on office Wi-Fi, they never see each other. AirDrop is similar — the devices have to be close enough. Browser-based direct transfer does cross networks: the connection details are exchanged once through a server, then the two sides pair up over the internet. This site is in that second group, and when a direct link genuinely can't be made (some corporate or campus networks block it) it switches to a relay and says so on screen.
Which one is "WebDrop"?
The name doesn't belong to a single product. There are at least five: an open-source browser group-transfer tool, a site built around peer-to-peer transfer plus chat, a Chrome extension (which actually relays through the cloud and caps file size), another site with the same name, and an Android app that runs a small local server so others can fetch files from a browser. So when you find a «how to use WebDrop» guide, check which one it means — the mechanisms differ completely, and some aren't peer-to-peer at all.
Which of these need nothing installed at all?
Snapdrop, PairDrop, WeTransfer and this site all run from a web page, with nothing to install on either side. LocalSend needs its app on every participating device. AirDrop needs no install either, but only because it is part of Apple's operating systems — non-Apple devices don't get the option at all.
