Connect with one person
Both people open this page. One creates an invitation and shares its code. The other pastes it, creates an answer, and sends that answer back. The first person pastes the answer to connect.
Codes contain network connection details, including possible IP addresses. Share them only with someone you trust. Cloudflare STUN helps find a direct path; restricted networks may need TURN and may not connect here.
Ready to connect
Send a file directly
Files travel over the direct encrypted WebRTC data channel. This page does not store them. Up to 20 MB per file.
How to use it
Connect two browsers with invitation and answer codes, choose a file, and send it to the peer.
What to check
Both browsers must stay open. A public STUN server sees connection metadata; some networks need a TURN relay, which this free tool does not provide.
Review the result before using it in a published page, application, or agent configuration.
