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.
Frequently asked questions
How fast are the file transfers?
Transfer speeds depend on your local network speed. On a typical WiFi network, you can expect speeds of 10-50 MB/s, often much faster than cloud upload services.
Are there any file size limitations?
There are no artificial file size limits imposed by our service. The only limitation is the available storage space on the receiving device and your patience for the transfer time.
Is this secure?
Yes! Files are transferred using WebRTC with end-to-end encryption. The data never leaves your local network and never touches our servers.
Do both devices need to be on the same WiFi network?
Yes! Both sender and receiver devices MUST be connected to the same WiFi network for successful file transfer. This ensures maximum speed and security.
What file types are supported?
All file types are supported - documents, images, videos, archives, executables, and more. We don't process or modify your files in any way.
Can I send files to multiple devices at once?
Currently, each room supports one sender and one receiver. For multiple recipients, you'll need to create separate rooms.
What if the connection fails?
If the connection is interrupted, you can simply rejoin the room and restart the transfer. The app will attempt to reconnect automatically.
Do you store any of my files?
No, we never store your files. The transfer happens directly between your devices, and our servers only help establish the initial connection.
