FAQ

Are files uploaded to UUUP?

No. Cloudflare relays encrypted connection metadata only. File content travels through a WebRTC DataChannel and is not stored by UUUP.

Why can a connection fail?

This tool uses free STUN-assisted direct connections and no TURN relay. Restrictive corporate, campus, or carrier networks may block P2P connectivity.

How large can a file be?

The streaming desktop path supports up to 10 GB per file and 20 GB per batch. Browsers without direct disk writing use lower limits.
