A secure Swiss vault for your file backups
When you store files in Proton Drive, they’re automatically protected with end-to-end encryption on secure servers based in Switzerland. Proton never has access to your files, documents, and photos.
As a company founded by scientists, our mission is to protect online privacy and build a better internet where you’re in control of your data, not Big Tech. We don’t scan your files or target you with ads.
Why use Proton Drive file backup?
Enjoy Swiss privacy, no matter where you live
Proton is incorporated and headquartered in Switzerland. This means the files, videos, and other data you back up to Proton Drive are protected by Swiss privacy laws, some of the toughest in the world.
Defend against data breaches and hackers
Proton Drive uses advanced encryption and account security features to protect your data. Unlike other cloud storage services, our end-to-end encryption means that even if there were a breach of our servers, the files would still be encrypted.
Keep your files and metadata private
Your files contain important data, from ID numbers to financial documents. When you back them up to Proton Drive’s secure cloud, the contents of your files and associated metadata like file names are encrypted on your device before they are stored on our servers. So we can never scan your files or hand them over to the government.
Save space on your phone with automatic photo backups
Using our new automatic photo backup feature, your images and videos are always backed up, as long as you have an internet connection. Save space on your mobile device and keep your intimate memories private.
Get started with 5 GB free cloud storage
Secure your files, documents and photos with end-to-end encryption
Encrypt all files automatically
Every file backup is encrypted on your device before uploading to our servers and stays that way until you download it again.
Sync files and folders
File backup syncing means any changes to a folder are mirrored in the cloud. Even if your device is broken or stolen, you won’t lose what’s most important to you.
Own your data
No one has the right to access your private files except you and the people you choose to share them with. Proton Drive ensures no one — not even Proton — can see your documents, photos, and videos.
Additional backup features
Back up photos automatically
Your photos automatically sync to your secure drive at regular intervals. If your device is damaged or stolen, your photos will still be safe. Enable biometric or device lock to ensure your files are protected even if your device ends up in the wrong hands.
Save space on your device
After uploading files or photos, you can delete the copies on your phone or computer to free up valuable space. You can also view your files in Proton Drive without downloading them to local storage.
Share large files securely
Easily share your backed-up files by generating an end-to-end encrypted file-sharing link for any of them. You can share it with anyone, even if they don’t use Proton Drive. There’s no limit on the number of times a file can be downloaded using a file-sharing link.
