You're probably wondering: "If TransferX doesn't use any servers… how does it even work?"
Great question — and the answer is pretty cool.
With our new technology stack, TransferX no longer stores your files on any server. Instead, we use direct peer-to-peer connections powered by WebSockets, enabling you to transfer files securely and privately, without any middlemen.
In traditional systems, files are uploaded to a server, then downloaded by the recipient. But not here.
TransferX creates a temporary direct connection between your device and the recipient's device. This means:
This is made possible using WebSockets, a real-time communication protocol that allows devices to talk to each other directly over the internet, even across firewalls and NAT.
We've made file sharing effortless — whether you're on the same Wi-Fi network or miles apart.
Here's how it works:
As soon as you open TransferX, it scans your local network and shows nearby devices instantly. No setup, no pairing codes — just tap the device you want to send files to.
Not on the same network? No problem. Simply create or join a Private Room using a shared name or code. Devices in the same room, no matter where they are in the world, will be able to discover and connect to each other securely.
Once connected, your files are streamed directly over a peer-to-peer WebSocket connection — no uploads, no cloud, no middlemen. Everything stays between you and the recipient.
When the transfer is done, the session is closed and nothing is stored. If you want to send something back, just select the sender and send — just as easily.
Your data never touches the cloud. There's no storage, no logging, and no eavesdropping — not even by us.
Files are encrypted during transfer and vanish the moment the connection ends.
No uploads. No downloads. Just streaming. This makes transfers even faster and more efficient.
Because we don't host your files, our costs are lower — and we pass that benefit on to you.
TransferX is a passion project — no ads, no tracking, and no data harvesting. While we've removed all central storage costs, running the platform and improving it still takes time and resources.
