Secure file drop
Encrypt a file in your browser and share a one-time link. The server never sees your file or the key.
🔒 End-to-end encrypted (AES-256). The key stays in the link and never reaches the server.
⚠️ The link contains the decryption key after “#”. Anyone with the full link can download once. We can’t recover it if lost.
Send another fileHow it works
- Your file is encrypted in the browser with a random key (AES-256-GCM) — the key is never uploaded.
- The ciphertext is stored; the key lives only in the “#” part of your link.
- The link stops working after the download limit or the timer, and the file is deleted.
Send files securely with end-to-end encryption
Secure drop lets you share a file through a single one-time link. The file is encrypted in your browser with AES-256-GCM before it is uploaded, and the decryption key lives only inside the link you share — it is never sent to our server, so nobody but the recipient can open the file.
Because the encryption is zero-knowledge, even we cannot read what you send. You choose how many times the link may be downloaded or how long it stays alive; once that limit is reached the file is destroyed automatically.
What does end-to-end encryption mean here?
Your file is scrambled on your own device before upload, and the key to unscramble it is stored only in the link fragment. Our server holds nothing but encrypted bytes, so a breach or subpoena would reveal nothing readable.
How long is a file kept?
You decide: set a maximum number of downloads or an expiry time. The link stops working and the encrypted file is deleted as soon as either limit is hit.
Is there a size limit?
The free tier accepts files up to a couple of hundred megabytes; the Pro tier raises the limit to several gigabytes and extends how long files can be stored.
Do I need an account?
No. You can send an encrypted file anonymously. An account or a one-off Pro pass simply raises the size and retention limits.
