Runs in this browser tab

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.

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.

Choose a 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.
