The most advanced
encrypted file sharing
encrypted file sharing
Proton Drive protects all your files, including your shared files, with end-to-end encryption.
- Any file you upload is encrypted on your device before it is stored on our servers.
- We don’t just encrypt the content of your files, we also encrypt metadata such as names of files and folders, file extensions, file sizes, thumbnails, and more.
- End-to-end encryption ensures no one, not even Proton, can access your files, unless you have sent them a secure file-sharing link.
Share large files for free
Proton Drive has no size limit on shared files. If you can upload it, you can share it. Our high performance continuous encryption algorithm encrypts data while it's being uploaded, providing a speed boost that makes Proton Drive the best way to securely share large files.
Share files securely with encrypted links
Share files and folders securely with friends, family, and colleagues using secure links you can generate in one click. Your shared files are end-to-end encrypted, and Proton Drive offers advanced features that allow you to limit who can access the link and for how long. Our encryption makes Proton Drive the most secure file-sharing service available.
More file sharing features

Password-protected file sharing

Share files securely with anyone, anywhere, at any time
Share files and folders using our secure encrypted file-sharing links with anyone, regardless of their device, browser, or platform — they don’t even need a Proton account.
Use secure file-sharing links to prevent data breaches
Sharing files with Proton Drive provides better data security. Instead of sending or emailing a file, send an expiring secure file sharing link. This way, even if the recipient's email gets breached later, your confidential file is not leaked. Unlike peer-to-peer solutions, Proton Drive also ensures that your IP address is never exposed to the file recipient.
Advanced features
for secure file sharing
Revoke access in one click
Revoke access to shared files and folders at any point. This disables the secure file-sharing link and prevents anyone from being able to use it to access your file.
Password protect your links
For an added layer of security, you can password protect your file-sharing links, allowing you to limit access to your files to only people you’ve authorized.
Expiring links
Set an expiration date for your file-sharing links after which the link will automatically be disabled, preventing unauthorized access.
Track access
Monitor suspicious activity after you’ve shared files and keep track of the number of times your files have been downloaded.
Secure file sharing made easy
Proton Drive was built by Proton, the same company behind Proton Mail,
the world’s largest encrypted email service.
Our team has experience developing and implementing advanced encryption while also creating easy to use privacy services that are used by millions.
You do not need any technical knowledge or special skill to encrypt or securely share your files. Simply upload a file and create the secure file-sharing link, and Proton Drive will handle all the encryption automatically in the background.

File sharing with Proton Drive
Support
Create a shareable link
You can share files and folders from Proton Drive with anyone using secure shareable links. These links are generated locally in your browser, so Proton never has access to your files or folders.
Support
Password-protect your links
For additional security, you can protect your end-to-end encrypted shareable links with a password and set an expiration date after which the link will no longer work.
Support
Send large files and folders
You can’t send very large files or folders by email because the size of email attachments is limited. If you want to send attachments larger than 25 MB, you can share them with Proton Drive.
