The fastest path is direct: sender to recipient. Hosted delivery is available when both people cannot stay online at the same time.

A more human future for file sharing
Peer-to-peer transfer can move files directly between browsers. When that is not practical, Zelf creates a short-lived hosted transfer so the recipient can download later.

Before you send
Is Zelf file transfer free?+
Yes. You can create an encrypted transfer link or send files by email without creating an account.
How large can each file be?+
Cloud transfers currently accept files up to 300 MB each. Direct peer-to-peer transfer availability depends on both browsers and the connection.
How long does a transfer stay available?+
You choose a one-day or four-day expiration. Zelf removes expired hosted files automatically.
Can I send a folder?+
Yes, in browsers that support folder selection. The original folder paths are preserved inside the transfer.
Can I protect a transfer with a password?+
Yes. Open transfer options before sending and add a password that you share separately with the recipient.
