Best Free 10GB File-Sharing Websites with End-to-End Encryption

1. ChatOdyssey – Anonymous & Encrypted 10GB File Sharing

ChatOdyssey (🔗 Official Site) is a secure messaging platform that doubles as an end-to-end encrypted file sharing solution. It’s designed with privacy and anonymity in mind. Instead of traditional user accounts, ChatOdyssey issues unique encryption keys as user identities, meaning you don’t even need to provide an email to use its services. This approach not only safeguards your account but also virtually eliminates spam or unwanted access.

In terms of file sharing, ChatOdyssey is a strong contender for large transfers. You can share files up to 10GB fully encrypted right in your browser, ensuring that only you and your intended recipient can decrypt the files. The service emphasizes ease-of-use despite its advanced security – the interface is straightforward, and sharing a file is as simple as sending a secure link or using the built-in chat feature. Because of its messaging roots, ChatOdyssey also excels in real-time transfers and even works reliably on high-latency connections.

Key Features:

• Max File Size: Supports file transfers up to 10GB for free (no premium tier required).
• Encryption: End-to-end encryption (E2EE) at the browser level. Files are encrypted client-side before transfer, and only the recipient’s key can decrypt them.
• Usability: No registration required – users get anonymous secure access via encryption keys. It offers a web app and mobile apps for sharing; just generate a share link or send files through the ChatOdyssey messenger.
• Security & Privacy: Zero personal data collection. Temporary encryption keys and anonymous access prevent linking files to your identity; data is encrypted in transit and at rest, and the platform’s design blocks spam or malicious contacts.

2. Wormhole – Simple, Private File Sharing (Up to 10GB)

Wormhole is a popular browser-based file transfer service that gained fame as a spiritual successor to Firefox Send. It lets you send files up to 10GB quickly and securely – for free. Wormhole encrypts all files client-side before uploading to the cloud, ensuring even Wormhole’s servers cannot read your data.

Despite using strong encryption, Wormhole remains very user-friendly. No account or setup is needed. One standout feature is its speed: Wormhole uses peer-to-peer (P2P) technology to accelerate transfers when possible. If sender and receiver are online simultaneously, it sends the file directly between devices. If not, it falls back to a server relay with an auto-expiring link.

Key Features:

• Max File Size: 10GB per transfer.
• Encryption: End-to-end encryption (client-side) using AES-256, ensuring files “can’t be read by any intermediary.”
• Usability: Extremely simple web interface with no account needed; drag-and-drop file upload generates a link that expires after 24 hours.
• Security & Privacy: 24-hour link expiry, P2P speed when available, and a decryption key included in the link ensuring only holders can access the file.
