Send files, encrypted before they leave your device

A zero-knowledge WeTransfer alternative. Drop files, share the link — we only ever see ciphertext, and it’s deleted on expiry.

Files are encrypted in your browser with the real @shieldfive/crypto core before they leave your device. We store only ciphertext, in the EU.

Need bigger transfers, a history of what you sent, or to collect files from clients? ShieldFive does end-to-end encrypted storage and intake, with nothing left in plaintext on our servers.

What people send with it

Sending a password or an API key rather than a file? ShieldFive Secret Link encrypts it the same way and deletes it after one view.

Questions

How is this different from WeTransfer?
The files are encrypted in your browser before they are uploaded, and the decryption key rides in the link after the “#” — a URL fragment that browsers never send to a server. WeTransfer can read your files; ShieldFive only ever stores ciphertext.
Can you see the files or their names?
No. The file contents and the filenames are encrypted on your device with the key that lives only in the link. We store ciphertext and opaque metadata — nothing readable.
How big can a transfer be, and how long does it last?
A transfer can hold up to 20 files and 750 MB in total (streaming for multi-GB is a fast-follow). Without an account, a link can be downloaded 20 times and lasts up to 7 days, and one network can send up to 10 transfers or 2 GB a day. When the link expires or its downloads run out, the ciphertext is deleted.
Do I need an account?
No. Anyone can send a transfer for free. Signing in adds history and higher limits.
