how it works

Three steps. No account needed.

01

Drop it

Drag in a file or a whole folder. Up to 20GB anonymously, 50GB with a free account.

02

We encrypt it

Optional password protection encrypts every chunk in your browser. The key never leaves your device.

03

Share the link

Get a clean link the moment upload starts. Anyone with it pulls the file at full speed.

Built for the paranoid.

Zero-knowledge

Files are encrypted before they leave your browser. We store ciphertext, nothing else.

Truly anonymous

No email or signup required to send. No tracking, no profiling, no ads.

Parallel downloads

Chunked storage saturates your connection instead of trickling one stream.

Big files, whole folders

Send up to 50GB and drop entire directory trees with their structure intact.

Password protection

One toggle locks a file behind a generated key only your recipient holds.

No prying eyes

Not us, not your ISP, not the host. The math keeps it shut, not a privacy policy.

We literally can't read your files.

Encryption happens client-side with libsodium. The decryption key is derived from your password and never touches our servers. If you lose it, even we can't recover the file. That is the point.
