How it works

Drop. Send.
They just click.

Security happens automatically. You never need to think about keys, encryption, or blockchain.

STEP 01
📤
Drop your files
Drag files into the box above, add the recipient's email, hit send. Everything is encrypted in your browser before it leaves your device — no account needed.
STEP 02
✉️
They get a secure email
Your recipient gets an authenticated FileUp email with a download link. The decryption key travels inside the link itself — our servers never see it. No signup to download.
STEP 03
🪪
Register to unlock more
A free account adds a permanent quantum-safe identity, real-time chat, encrypted voice calls, and tamper-evident delivery receipts. Pro adds automation that works while you don't.
Invisible security

Your files.
Nobody else's business.

Post-quantum cryptography, decentralised identity, and a private blockchain — all working silently so you don't have to.

🔐
Quantum-resistant encryption
Files and messages are encrypted on your device with NIST-standard post-quantum ciphers (ML-KEM-768 + AES-256-GCM). Future quantum computers gain nothing from intercepted traffic.
⛓
Decentralised identity
Your identity is anchored on a private Proof-of-Authority blockchain. No central server can be hacked to impersonate you.
🔑
Your keys, your device
Private keys are generated in your browser and never leave your device. Even the relay servers only see encrypted blobs.
📋
Tamper-evident receipts
Every transfer generates a receipt anchored to a private blockchain — verifiable proof of who sent what, and when, without ever exposing the content.
