Transfer files directly between devices on local network without internet connection. No servers, maximum privacy.
Offline P2P transfer allows sharing files between devices on the same local network (WiFi or LAN) without requiring internet connection. Data never leaves your local network.
Unlike standard mode, where a signaling server helps establish the connection, offline mode uses QR codes or mnemonic words to exchange connection information directly between devices.
Offline transfer uses WebRTC technology, but instead of a server for connection setup, it uses QR codes or mnemonic words:
Choose role
One device creates an offer, the other connects as a joiner.
Share offer
First device displays a QR code or mnemonic words containing connection data.
Answer
Second device scans the QR and generates an answer, which it shares back.
Direct connection
After exchanging data, devices connect directly via local network and can transfer files.
Quick scanning with phone camera. Ideal for phone ↔ computer.
List of English words that can be read aloud. For cases without a camera.
Offline mode provides the highest possible level of privacy:
Data never leaves your local network. Even signaling doesn't go through internet.
WebRTC automatically encrypts all data using DTLS protocol.
Transfer happens only within your WiFi/LAN – no ISP, no internet.
Utilize full local network speed without internet connection limitations.
Transfer photos from mobile to PC without cloud services.
On airplane, at cabin, or in areas without signal.
Documents that must not leave the local network.
Utilize Gigabit LAN speed without internet limitations.
