Everything You Get with SecureEU
A complete set of features for secure, private file sharing — designed in Europe, for everyone.
Security & Encryption
Built on zero-knowledge architecture
End-to-End Encryption
AES-256-GCM via WebCrypto API. Files are encrypted in your browser before upload — we never see your data.
Zero-Knowledge Architecture
Encryption keys are passed only via the URL fragment (#), which never leaves your browser.
EU-Hosted Infrastructure
All servers and storage run in the EU (Hetzner, Finland) — fully GDPR compliant.
5 MB Chunk Encryption
Files are split into 5 MB blocks, each encrypted individually for maximum security and performance.
No Metadata Leakage
We never log file names, file contents, or encryption keys on the server.
Compliance Certificate
Download a transfer certificate with metadata, batch ID, and timestamps for audit purposes.
File Transfer
Powerful, fast, and flexible
Up to 50 GB
Transfer files up to 50 GB via S3 multipart upload with automatic retry.
6× Parallel Upload
Six concurrent chunk uploads fully utilize your bandwidth.
Folder Upload
Drag entire folders in — folder structure is preserved automatically.
Batch Transfers
Send multiple files at once and share them as a single link.
Real-Time Stats
See upload speed, elapsed time, ETA, and per-file progress in real time.
Drag & Drop
Drop files and folders directly in the browser — or use the file picker.
Sharing & Access Control
Full control over your shared files
Password Protection
Add a password to your link — hashed with SHA-256, with brute-force delay.
Custom Expiry
Free transfers: up to 7 days. Paid: choose 1, 3, 7, 14, or 30 days.

Send the download link directly to your recipient's email via SendGrid.
QR Code
Generate a QR code for your download link — perfect for mobile.
Download Notification
Get an email when your recipient downloads the files.

End-to-End Encrypted
Received files are encrypted in the sender's browser — you maintain full security.
