Big files. Zero knowledge, when you want it.

Optional end-to-end encryption, on the moment you turn on password protection. No account needed. Drop up to 20 GB and share a link that expires in seven days.

Zero-knowledge

Turn on password protection and your files are encrypted in the browser, before a single byte moves, so the server stores ciphertext and nothing else. We cannot read those files, hand them over, or recover them for you.

Anonymous

No account, no email, no card. A key kept in your browser lets you manage what you dropped. Lose the key and the upload is simply gone.

Fast

Encryption streams in chunks, so uploads start immediately and the share link works before the transfer finishes. Send it now, let the bytes catch up.

Whole folders

Drop a directory and the structure survives the trip. Up to 20 GB per anonymous drop, kept for seven days. A free account gives you 10 GB that stays until you delete it.

Request files

Turn it around: send a request link and have clients or colleagues drop files straight into your account, no sign-up on their end. See who delivered what, and when. Secure delivery, both directions.
