Free, private, peer-to-peer file sharing — no accounts, no servers, no limits.
Yunze Universal Transfer was built with a single goal: to make file sharing as simple and private as handing someone a USB drive — but from anywhere in the world. We believe that sharing files shouldn't require uploading your data to a corporation's servers, creating accounts, or worrying about file size caps.
Yunze was created and is maintained by the Yunze team as part of a growing suite of web-based productivity tools. Every product we build prioritizes simplicity, privacy, and accessibility.
Yunze uses WebRTC (Web Real-Time Communication) technology — the same technology that powers video calls in your browser — to establish a direct, encrypted connection between two devices. Once a connection is made, files travel directly between those two devices without ever passing through our servers.
The connection is brokered through PeerJS, an open-source signaling library. The signaling server only helps two devices find each other — it never sees your file data.
🔒 Your files are never stored on Yunze servers. We have no access to what you share. When the connection closes, everything is gone.
Most file sharing services work by uploading your file to a cloud server, storing it, and giving the recipient a download link. This means your file sits on someone else's computer — sometimes indefinitely. Yunze eliminates this entirely.
Yunze is an independent software team focused on building clean, fast web tools. Our products share a consistent design philosophy: minimal interfaces that get out of your way and let you focus on your work. Follow us on Instagram @yunze_official for updates.
