How does FastSend P2P transfer files without cloud storage?

FastSend establishes a direct peer-to-peer WebRTC data channel between sender and receiver. Chunks of data stream memory-to-memory directly through an encrypted socket without being uploaded or stored on any intermediate server.

Is there a limit on file size?

Unlike cloud services like WeTransfer (2GB cap) or Google Drive (account storage limits), FastSend P2P transfers files directly from disk to disk, allowing you to send 10GB, 50GB, or even 200GB files seamlessly.

Are my files encrypted during transfer?

Yes. FastSend uses Noise protocol cryptography with 256-bit ephemeral keys. Only your devices can decrypt the file streams.
