How it works
Share files over your local WiFi network in 4 simple steps
Click Send Files
On the sending device, click "Send Files" button. A secure room is created automatically — no manual setup needed!
Share Room ID or QR Code
Share the auto-generated room ID or QR code with the receiving device. QR code makes sharing instant and effortless.
Receiver Joins Instantly
On the receiving device, scan the QR code (auto-joins) or manually enter the room ID to connect to the secure session.
Select and Send File
Choose your file and click send. WebRTC establishes a peer-to-peer connection and transfers at full WiFi speed with real-time progress.
Download Complete
The receiver downloads the file once transfer completes. Everything happens locally — no cloud storage, maximum privacy!
Technology behind the magic
WebRTC Technology
We use WebRTC (Web Real-Time Communication) to establish direct, encrypted connections between your devices without going through external servers.
Local Network Only
Files are transferred directly over your local WiFi network, ensuring maximum speed and privacy without using internet bandwidth.
Optimized Performance
Chunked file transfers with flow control ensure stable transfers even for large files, with progress tracking and error recovery.
Cross-Platform
Works on any device with a modern web browser — smartphones, tablets, laptops, and desktop computers.
- Both devices MUST be on the same WiFi network
- Room is created automatically when you click "Send Files"
- Scan QR code for instant connection
- Room persists on refresh — no need to recreate
- Connection is end-to-end encrypted and secure
