How it works

Share files over your local WiFi network in 4 simple steps

simple process

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.
