Why send files with ZetaShare?
Direct Peer Connection
Files go peer-to-peer over WebRTC — no server stores them. When several people download the same link, a swarm of peers shares pieces with each other so the sender is not the only source.
Low-Latency Transfers
Transfers happen quickly over a direct UDP connection between users.
3-Layer Quantum Encryption
Every transfer is wrapped in three post-quantum layers — ML-KEM-1028, ML-DSA-87, and SLH-DSA-256 — on top of DTLS 1.3, so the session stays private even against future quantum attacks.
Customizable Sharing
Set a password or create a custom link for files you share.
No File Size Limits
Send files of any size, with no limits or premium plans required.
Browser-Based
Works directly in any modern browser — no installation needed.
