    Proton Drive's strong encryption goes beyond other secure cloud solutions.

    End-to-end encryption ensures that no one, not even us, can access your files. Files, file names, folder names, and more are all fully encrypted at rest and in transit to your secure cloud.

    Swiss privacy

    Proton is based in Switzerland, which means your files are protected by some of the strictest privacy laws in the world. Proton Drive is a neutral and stable digital vault for your files.

    Open source

    We believe in trust through transparency. Proton Drive is open source, so anyone can verify that our encrypted cloud storage works as described. Proton Drive is also routinely audited for privacy and security by independent third-party experts.

    Built on freedom and privacy

    Choosing Proton Drive is a step towards a better internet. Proton Drive is part of a wider ecosystem of privacy-first products. By using Drive and our other products, you are helping to create an internet where people, not Big Tech, hold the power.

    Collaborate on documents while protecting your privacy

    The documents you create in Proton's Docs are end-to-end encrypted, ensuring your work can never be exposed in data breaches, subject to online surveillance, or used to train AI models. Docs is integrated into Proton Drive, meaning you have a unified and secure space for creating, collaborating, and storing your documents. We designed Docs to be a clean, simple experience. With Docs, you can:

    • Write with privacy
    • Share and invite anyone
    • Collaborate in real time

    Stay in control of shared files

    Proton Drive's end-to-end encryption also works when sharing files and folders.

    Optional features like password-protected files and expiring file-sharing links enhance security even further. Best of all, there are no file size limits.

    Safeguard your memories in a vault

    Your files are more than just data. The photos and videos of time spent with your family and friends are a record of your life. These images, along with your other personal documents, deserve the highest protection and privacy.

    Proton Drive is a secure and encrypted Swiss vault for your favorite moments.

    Know you can always access your files

    With Proton Drive, your files are accessible 24/7 from any device and secured with automatic backups in multiple datacenters. Your data remains safe even if you lose your phone or computer.

    Our end-to-end encryption means that unlike other cloud storage solutions, you don't have to share access to your most intimate files with a third party. Unlike Big Tech, Proton can't access your files. Your data remains fully owned, accessible, and controlled by you.

    Make it your own

    Organize and personalize your encrypted drive to make it your own.

    Customize your Swiss vault

    Just because Proton Drive is secure doesn’t mean it can’t look good as well. Choose your favorite layout and theme, including dark mode options.

    Encrypted file search

    All files in Proton Drive are end-to-end encrypted, but our unique encrypted search technology makes searching for encrypted files possible.

    Put passwords on your files and folders

    When sharing files or folders, you can password protect the links, authorize specific users, and set expiration dates to prevent unauthorized access.

    Data stored on Drive is accessible only to your organization and those you share it with. Our end-to-end encryption means that even Proton cannot read the files stored in your organization’s Proton Drive account.

    Even if we suffered a data breach, your files would remain securely encrypted. Together with Proton Mail, Proton Calendar, and Proton VPN, we provide a powerful suite of privacy-focused services.

    Why choose Proton Drive?

    Proton Drive is a file storage solution that combines the convenience of the cloud with the privacy of a Swiss vault. With Proton Drive, you can easily access your data while benefiting from end-to-end encryption.
