Files up to 50 MB via a temporary one-time link
Per-chunk integrity protection against tampering
Optional expiry and recipient approval

Häufige Fragen (FAQ)

How does the zero-knowledge file transfer work?

The file is encrypted in your browser. The decryption key stays in the URL after # and is never sent to the server, which only stores encrypted chunks.

Are my files safe on the server?

The server only stores encrypted data blocks. Without the local key from the URL the container cannot be decrypted.
