OnionShare – Securely and anonymously share files via Tor network

In this digital world, there are already too many traditional online file sharing services, but they are not secure (not anonymous or even transparent), free (various restrictions) or permanent (can delete your files or even shut down at any time, for any so-called reason) enough. Although Bit Torrent and its derivatives can share files freely, they are still not secure or convenient enough. So there is OnionShare, a good alternative to all online file sharing services.
