Discover how peer-to-peer technology enables fast, private, and secure file sharing.
P2P (Peer-to-Peer) is a network architecture where devices communicate directly with each other, without going through a central server. Each device acts as both client and server.
In P2P file transfer, your files travel directly from your device to the recipient's device. No cloud storage, no middleman, no waiting for uploads.
Direct Connection
Files go straight from sender to receiver
Enhanced Privacy
No third party sees your files
No Central Point
Decentralized, resilient network
P2P file transfer in the browser uses WebRTC technology. Here's how it works:
Devices find each other using a signaling server. This only exchanges connection info, not your files.
A direct encrypted channel is established between devices using DTLS encryption.
Files are split into chunks and sent directly through the P2P connection.
Recipient assembles the chunks into the complete file. Nothing stored anywhere.
Your Device
Direct Encrypted Connection
Recipient
Files travel directly between devices. The signaling server only helps establish the connection.
P2P transfer offers several security advantages over cloud-based file sharing:
Files never rest on third-party servers where they could be accessed or breached.
Data is encrypted from your device to the recipient's device with no decryption in between.
After transfer completes, there's no copy of your file anywhere except on intended devices.
No central server means no single point of failure or target for attackers.
Sensitive Documents
Financial, legal, or personal files that shouldn't be on cloud servers.
Large Files
Videos, RAW photos, or project files too big for email or cloud limits.
Same Network Transfers
Fastest possible transfer between devices on your local network.
