Questions & answers
Is it really free?
Yes. WiFiPeer is free to use. The site is supported by ads shown on content pages like this one.
Do my files get uploaded anywhere?
No. Files travel directly between your two devices over an encrypted WebRTC connection. The signaling server only helps the devices find each other — it never receives the file itself.
Is there a file size limit?
There is no fixed cap. Large files are split into small chunks and streamed with flow control, so multi-gigabyte transfers are possible as long as both devices stay connected.
Which devices and browsers work?
Any modern browser that supports WebRTC — recent versions of Chrome, Edge, Firefox and Safari on both desktop and mobile.
Do I need to install an app?
No. Everything runs in the browser. Open the site on your computer, scan the code with your phone, and transfer.
How long does a session last?
Sessions are temporary and expire automatically after about ten minutes. Just reload the page to start a fresh one.
The connection failed — what now?
Some corporate or public networks block direct connections. Try both devices on the same Wi-Fi. For production use, a TURN relay server can be configured as a fallback.
