Proton Drive for Web

Quick summary

Proton Drive is a cloud storage service from Proton AG that uses a freemium model. It provides browser-based access to your files, strong end-to-end encryption, and a free tier that should suit many individual users. Larger storage quotas and extra enterprise-grade controls are available with paid subscriptions.

Core capabilities

• Browser access from any internet-enabled device, no desktop client required
• Free 15 GB account storage included upon signup
• Support for single file uploads up to 10 GB
• Clean, file-explorer-style interface with built-in sharing tools

Security and privacy details

Proton Drive encrypts files end-to-end so that only you and the people you authorize can read the content. This encryption is part of Proton’s broader ecosystem (which also includes secure email and a calendar), and most of these privacy protections are included with the free plan. You must create an account to use the service, and every session requires signing in — using a password manager can simplify that step.

Sharing and collaboration

You can share items in your Drive via links similar to other cloud services. Shared links can be protected with a password, but that password needs to be communicated separately to recipients. The platform also allows controlled access to an entire drive, so you can restrict who can view or download files.

Plans and business options

• Free accounts include basic encryption and 15 GB of storage.
• Paid tiers unlock larger storage quotas and additional security features.
• There is a Proton for Business offering that bundles email, communications, and other tools useful for small IT environments.

Limitations to keep in mind

• No offline access — files are available only when you have an internet connection and are signed in.
• Some advanced security and storage options require a paid subscription.
• Uploads are capped at 10 GB per file, which may affect very large media or archive uploads.

Who this is best for

If you prioritize privacy and want a lightweight, secure cloud drive for personal or small-team use, Proton Drive is a solid option. The free tier covers most everyday needs, while paid plans are available for those who require more space or enterprise features.
