LAN File Transfer

A browser-based local network file transfer tool inspired by LocalSend. Devices on the same network discover each other automatically through a shared room and exchange files via encrypted WebRTC peer-to-peer connections — no accounts, no cloud uploads, no software installation required.

Core Features

• LAN Device Discovery: Devices in the same room appear automatically, showing name, type, and online status
• Peer-to-Peer Transfer: Files travel directly between browsers through WebRTC data channels, bypassing any server relay
• Selective File Acceptance: Recipients can review incoming files and choose which ones to accept before the transfer begins
• PIN Protection: Optionally set a PIN to require verification before files can be sent to your device
• Multi-File Support: Send multiple files in a single session with individual progress tracking per file

How to Use

Connect to a Room

1. Open the tool on each device — a signaling connection is established automatically
2. Both devices must join the same room (default room is "local")
3. Once connected, nearby devices appear as clickable cards with device name and type

Send Files

1. Click the card of the device you want to send files to
2. Select one or more files from the file picker
3. Wait for the recipient to accept the transfer
4. Progress is displayed in real time for each file

Receive Files

1. When someone sends you files, a dialog appears listing all offered files with their sizes
2. Select which files to accept using the checkboxes
3. If the sender has a PIN set, enter it in the dialog
4. Click "Accept" to begin receiving — files are saved automatically once complete

Settings

Expand the settings panel to customize your device name, change the room, or set a PIN. Click "Apply" to update your profile, or "Reconnect" to refresh the connection.

Use Cases

• Transfer photos, documents, or archives between your phone and computer on the same Wi-Fi network
• Share files with colleagues during a meeting without exchanging email addresses or using cloud services
• Send files to nearby devices quickly using only a browser — ideal when USB cables or AirDrop are unavailable
• Securely transfer sensitive files within a private network using PIN protection

Comparison with Similar Tools

Unlike cloud-based file sharing services, LAN File Transfer keeps all data within your local network. Compared to LocalSend (which requires a native app), this tool runs entirely in the browser. Similar to ShareDrop, but with added features like PIN protection and selective file acceptance.

Notes

• Both devices must remain on the page with the browser tab open during the entire transfer
• Transfer speed depends on local network conditions between both peers
• If a transfer is interrupted, it must be restarted from the beginning
• WebRTC requires a compatible browser — Chrome, Edge, Firefox, and Safari are all supported
• All signaling occurs through the server, but file data is transmitted directly between devices
