Safe and secure link sharing
You can password-protect any file-sharing link you create in Proton Drive for additional security.
This prevents unauthorized access to your file, even if the link falls into the wrong hands. Proton Drive also allows you to set an expiration date for your shareable link or revoke access in a single click.
You can create a secure file sharing link for files of any size. Proton does not impose any size limits on your uploads, so your only constraint is the amount of available storage left in your drive.
Link sharing across all devices
The best file-sharing method for any file
Link sharing with Proton Drive is the safest and most flexible way to share files of any size without the need to compress them. Proton Drive also supports all file formats, including 4K videos, lossless RAW images, and PSD files. You can even use Proton Drive’s share links to transfer executable (.exe) files, which many email services will not let you send as attachments.
