Sync your files securely with Proton Drive

Sync device to cloud

Sync files or any folder, not just your My Documents or My Music folders, from your Windows device to the cloud. Any edit you make to these files and folders will automatically update across all your Proton Drive apps.

Sync on demand

Free up storage space on your Windows or macOS device by downloading files only when you need them. Files only take up space on your device when you sync them from the cloud and open them. You can also select “keep on this device” for permanent offline access.

Sync across devices

Your synced files are available on all your devices with our apps and web app. Access the most up-to-date version of your file no matter where you are.

Protect your files with Proton

When you sync your files to your secure Proton Drive vault, they’re encrypted on your device before they reach our servers. Unlike other file sync services, no one can access your uploaded files but you.

Proton Drive was developed by the same team that built Proton Mail, the world’s largest encrypted email service. We applied the lessons we learned from Mail to Drive, allowing us to ensure your files are always safe, no matter if you access them from your desktop, laptop, or smartphone.

Sync files across all your devices

At Proton, we believe your information belongs to you. Unlike some cloud storage competitors, who rely on exploiting your data for profit, we protect your information because we believe everyone has the right to privacy. 

With the support of our community, we’re building an entire suite of easy-to-use encrypted services to make it easy for anyone to keep their data safe. Join us and help create a better internet where privacy is the default.
