Free cloud storage to protect your files

Free secure cloud storage

Proton Drive is a secure vault that protects your files and your privacy. Our free cloud storage is the only one that is:
  • End-to-end encrypted
  • Free forever with no ads
  • Open source and audited
  • Protected by Swiss privacy laws
  • End-to-end encrypted cloud storage for everyone

    All files on Proton Drive are protected with end-to-end encryption, regardless of whether you have a free or paid plan. End-to-end encryption means that nobody, not even us, can decrypt the files that you upload, guaranteeing the privacy of your files.

    Free cloud storage with premium features

    Unlimited file sharing

    Proton Drive doesn’t impose any limits on the number of people who can use your file sharing link, whether you have a paid plan or not. You can also share files of any size for free; the only limit is the remaining storage in your drive. For extra storage, you can upgrade to Drive Plus or a Proton Unlimited account.

    Share files with a link

    You can share your end-to-end encrypted files with anyone by creating a file-sharing link for free. Proton Drive’s link sharing feature includes the option to revoke access to your file at any time, or set an expiry date, giving you full control of who can access your file and when.

    Password-protected file sharing

    You can make your end-to-end encrypted file sharing links even more secure by password-protecting them. Setting a password protects your file even if the file sharing link falls into the wrong hands, only those who know the password will be able to access the file.

    Multi-platform sync

    Proton Drive automatically synchronizes the files you upload across all your devices. For example, if you upload a file in your web browser, you will be able to access it in the Android or iOS app on your mobile device.

    Encrypted file search

    Proton Drive’s encrypted search function allows you to quickly look up any file in your drive by creating a local index of your files on your device. This means you can easily find a specific file without anyone — not even Proton — knowing its contents.

    Share files with anyone

    You can share your encrypted files for free with anyone, even if they do not have a Proton Drive account. Your shareable links can be accessed by anyone with the link (and any password you have set), and remain protected with end-to-end encryption the entire time.

    Why use Proton Drive Free

    Free file sharing

    Share large files securely for free via encrypted links that can be generated in one click. Additional features such as password protection, expiry dates and easy-revoke deliver maximum control over shared-links.

    Access files from anywhere

    Files sync automatically across devices so you can access stored files from your desktop, mobile or web browser. With Proton Drive you can access your files securely from anywhere, at any time.

    Free file backup

    Proton Drive automatically backs up your files to the cloud, unlike SSD and other local storage. Your uploaded files can even be made available offline. This means your files are safe and accessible even when your hardware or internet malfunctions.

    Swiss Flag

    Swiss data protection

    Proton Drive is based in Switzerland which protects you from government surveillance as it is not a member of any intelligence-sharing alliances like the Five Eyes(new window) and also has some of the world’s strongest data privacy laws.

    Secure cloud servers

    Proton owns and operates all the servers that your files are hosted on. This makes Proton Drive more secure than cloud storage services that use third party hosting such as Amazon Web Services or Microsoft Azure.

    Easy to use

    Proton Drive uses robust end-to-end encryption without compromising on great design or ease of use. Your free account comes loaded with features that make it remarkably easy to store, share, and sync your files safely and securely.
