File transfer, reinvented
We built the platform we wished existed. Fast, secure, no complications.
AES-256-GCM Encryption
Your files are encrypted with AES-256-GCM, the same algorithm used by banks and defense organizations worldwide. It is considered unbreakable with current technology.
Zero-Knowledge Architecture
The encryption key is generated exclusively in your browser and never reaches our servers. We cannot access your files - not technically, not legally, not under any circumstances.
Key in URL, Not on Server
The decryption key is transmitted to the recipient via the URL fragment (#key=...). Browsers never send the fragment to the server - it never appears in any access log and cannot be intercepted by us or third parties.
Web Crypto API
Encryption is handled by the browser native Web Crypto API, not a third-party library. This means no external code can intercept your data during the encryption process - the implementation is audited and maintained by browser vendors like Google and Mozilla.
Encrypted Before Upload
The entire file is encrypted in your browser before being split into chunks and uploaded. Even if a chunk were intercepted in transit, it would be completely unreadable without the key that never leaves your browser.
End-to-End Encryption
Your files are encrypted before leaving your device. Nobody can access them, not even us.
Password protection
Add a password to your transfer and only the recipient who knows it can download the files.
2FA Authentication
Protect your account with 2-step verification. 6-digit code via email on each login.
Email Verification
New accounts are only activated after confirming the email address, preventing fake registrations and automated spam.
Login History
View all authentication sessions: IP address, device and date of each login, to quickly detect unauthorized access.
Large files, no problem
Chunked uploads with automatic resume. Transfer files up to 50 GB without interruptions.
Email notifications
The recipient automatically gets an email with the download link. You get confirmation when they download.
Auto-expiration
Files are automatically deleted after the set period. No forgotten data left on the server.
Self-Destroy
The file is automatically deleted after the first download. Ideal for confidential documents that should not be shared further.
File Preview
Recipients can preview images, PDFs and documents directly in the browser, without needing to download the file.
Folder Upload
Select an entire folder to send - it is automatically archived as a ZIP in the browser before upload, with no manual archiving needed.
File Request
Send a link and receive files from anyone. Ideal for accountants, lawyers, agencies — clients upload directly to you.

Custom expiry
Choose the exact date and time your download link expires. You decide when files disappear — not your plan's default.
Download limit
Restrict how many times a link can be accessed. Great for controlled distribution — the link auto-deactivates after the set number of downloads.
Voice Message
Attach a voice message recorded directly in the browser to your transfer. The recipient can listen before downloading.
