Peer-to-peer file transfer

Files fly straight
between your devices.

Open AirBridge on two devices, share a six-character code, and drop in a file. Bytes stream across an encrypted WebRTC channel — nothing touches our servers, no sign-up, no waiting for an upload to finish.

Works on every phone

iPhone talking to Android. Android talking to iPhone.

AirBridge doesn't care what shape your phone is. Any modern browser opens a direct WebRTC channel to any other modern browser — the file goes across in seconds.

Get AirBridge

Every device in your pocket.

iOS and Android apps are in the oven — same peer-to-peer protocol as the web version, just with native share sheets and background transfers. In the meantime, the browser works on every phone.

Use it in theBrowser

Right in your browser

Nothing to install. No accounts. No upload wait.

Open airbridge in one tab, enter the code on another device, and the bytes are already on the way. This is the whole interface.

How it works

Three steps, zero friction.

01

Open on both devices

Visit AirBridge on the sending and receiving device. Works in any modern browser — nothing to install.

02

Share the six-character code

The sender gets a short code and a QR. Read it aloud, text it, or scan — whichever is easiest.

03

Files go directly

Once paired, the file streams straight from sender to receiver over an encrypted WebRTC channel. We never see the bytes.

Perfect for

The moments cloud storage is overkill.

AirBridge fits into the gap between "drop it in a DM" and "spin up a shared drive". Six characters, two devices, gone.

Phone → laptop photos

Drag the week's photos off your phone onto your laptop without opening iCloud or iMessage.

Big videos, no cloud limits

A 6GB family-birthday clip doesn't fit in a Gmail attachment. AirBridge doesn't care about size.

Sending a client a file

Share a private doc without uploading it to Drive or Dropbox. The client just opens the code.

Between family devices

Your mum's iPad, your dad's Windows laptop, the shared Android tablet — all the same code.

Sensitive handoffs

Legal docs, payroll, anything you'd rather not park on a third-party server. Peer-to-peer only.

Public-WiFi speed

Transferring between two phones in the same café? Local-network throughput kicks in automatically.

Why AirBridge

Private by default. Fast by design.

Your files, nobody else's business

Bytes flow peer-to-peer over an encrypted DataChannel. AirBridge never stores, mirrors, or inspects the file.

No upload wait

There's no upload queue — transfer starts the moment the receiver joins, and runs at the speed of your network.

Works everywhere a browser does

Mac, Windows, Linux, iOS, Android — anything with a modern browser. No app install, no account, nothing to remember.

Built for the moment

Share the code, send the file, move on. Codes expire when the tab closes.

Try it in ten seconds.

Open a second browser tab or grab your phone. Send yourself something.

Questions

The short answers.

Is this really free?
Yes. No accounts, no trial period, no feature tiers. We don't run ads either. The service is thin enough that running it costs close to nothing — there's no business model hiding in a later version.
What file sizes can I send?
Whatever your two devices can hold. AirBridge streams the file 64KB at a time and doesn't buffer the whole thing in memory, so multi-GB transfers work fine. The receiver's browser assembles the file as it arrives and saves it to Downloads.
Do both devices need to be on the same network?
No. WebRTC handles the NAT traversal — the two browsers find each other over the internet and open a direct connection. If they happen to be on the same LAN, the transfer runs at local-network speed automatically.
Can I use it on public Wi-Fi?
Yes. The DataChannel is encrypted end-to-end regardless of the network you're on — even on a café or airport Wi-Fi, nothing between the two devices can read the bytes.
Why is it faster than Google Drive or Dropbox?
There's no upload queue. With cloud storage, the sender has to finish uploading before the receiver can start downloading. AirBridge streams the file directly, so the receiver sees bytes as soon as the sender sends them — end to end at the speed of the slower of the two connections.
Does it work between iPhone and Android?
Yes. Any modern browser on either OS opens the same WebRTC channel. Safari on iOS, Chrome on Android, Firefox on desktop — all interop.
Can I resume an interrupted transfer?
Not in this version. If a transfer drops mid-stream (one side closes the tab, the network changes, etc.), reopen AirBridge and start again with a new code. Resumable transfers are on the roadmap.
What happens to my files on the server?
Nothing. The signaling relay exchanges a few kilobytes of WebRTC session metadata (SDP + ICE candidates) so the browsers can find each other. The file bytes never pass through any AirBridge infrastructure. See the privacy policy for the full breakdown.
