How encrypted file sharing works
Three steps. No accounts. No tracking. Your privacy is built into the protocol.
Drop your file
Select any file up to 50 MB. It never leaves your browser unencrypted.
Automatic encryption
Your file is encrypted with a unique AES-256-GCM key generated in your browser.
Share the link
The decryption key is embedded in the URL fragment. Only the recipient can decrypt.
Built for privacy, designed for simplicity
Browser encryption
Files are encrypted with AES-256-GCM before they leave your device. The server never sees your data.
Zero-knowledge
The encryption key lives only in the share link fragment. We cannot decrypt your files, even if compelled.
Auto-expiry
Set files to expire after 1 hour, 24 hours, or 7 days. Expired files are permanently deleted.
Burn after read
Enable one-time access so the file is destroyed after a single download.
