Encrypted cloud storage for all your files
Proton Drive's rigorous encryption goes beyond all 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 the secure cloud.
The safest way to share 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.
Free file storage
We believe everyone has the right to privacy. Our free Proton Drive plan includes all the security and privacy features of our paid subscriptions, making it the best free encrypted cloud storage solution.
To access more storage and support our fight for a better internet, upgrade to a paid account.
Why use Proton Drive?
With Proton Drive, your files are accessible 24/7 from any device and secured with automatic backups. Your data remains safe even if you lose your phone or computer.
However, end-to-end encryption means that unlike other cloud storage solutions, you don't have to share your most intimate files with a third party. Unlike Big Tech, Proton can't access your files. Your data remains fully owned and controlled by you.
