Basics
What is free cloud storage?
With cloud storage, files aren't stored exclusively on your computer or smartphone; they are kept on the servers of a cloud provider. This means they can be accessed over the internet from different devices.
Many providers operate a freemium model. A limited amount of storage can be used for free indefinitely, while larger storage quotas or additional features require a paid plan.
Free does not necessarily mean the same feature set as a premium plan. Depending on the provider, aspects such as maximum file size, versioning, additional security features or other performance characteristics may be restricted.
Important: A large amount of free storage does not automatically make a service the best option. What matters is whether storage size, security, apps, synchronisation and possible limitations suit your use case.
What should you look for in free cloud storage?
Storage space Depending on the provider, only 2 GB or up to 20 GB may be available for free. Photos and videos in particular can quickly fill small quotas.
Shared storage On some platforms the quota is shared across different services. As a result, the full advertised storage amount may not be available solely for files.
Upload limits Some providers limit the maximum size of individual files. This can be especially relevant for videos, archives and backups.
Synchronisation Good desktop and smartphone apps ensure files are kept up to date automatically across multiple devices.
Privacy Data location, company headquarters and the encryption used can vary significantly between providers.
End-to-end encryption Highly sensitive files can benefit from services where only the user holds the necessary key for decryption.
File sharing If you regularly share files with friends, customers or colleagues, look for simple shareable links and appropriate permission options.
Upgrade costs If the free storage later proves insufficient, the price and feature set of paid plans can be decisive.
How much free cloud storage do you need?
How much storage makes sense depends heavily on which files are stored in the cloud. Text documents require little space, whereas high-resolution photos and especially videos demand much larger amounts of data.

Privacy and security for free cloud storage
Anyone who stores personal documents, photos or other sensitive data in the cloud should not only consider the amount of storage. Equally important is how the provider protects the stored data.
Encrypted data transmission is standard for modern cloud services. Distinct from this is true end-to-end or client-side encryption. With that, data are encrypted on the user's device before being uploaded to the cloud.
The location of the provider or of the data centres used can also play a role. While major services such as Google, Microsoft, Apple, Dropbox and Box originate from the US, providers like Infomaniak, pCloud and Proton position themselves deliberately as European or Swiss alternatives.
Tip: For particularly sensitive documents you should not rely solely on the label "encrypted". What matters is whether this refers only to encrypted transmission and storage, or to genuine end-to-end encryption.
