Email has been a standard communication tool for decades, but when it comes to sending large files, it often falls short. Most email providers impose strict file size limits, leaving you searching for alternative solutions. But what if you could share large files securely, quickly, and without compromising your privacy?

AliasCrypt makes that possible. By combining encrypted streaming with anonymous mailboxes, you can send files up to 4GB directly, without relying on unsecured cloud storage or compressing sensitive documents into risky formats. Files are encrypted end-to-end and never stored in a way that third parties can access.

You don’t even need an account. With just your recipient’s public key or alias, you can transfer files without revealing your identity. Once delivered, files are automatically deleted, ensuring they’re never lingering online.

If you’re already using AliasCrypt as a secure messaging app, this functionality integrates seamlessly — giving you one platform for both messages and file transfers. For businesses, this also overlaps with our enterprise file transfer capabilities, perfect for managing confidential data at scale.
