What Is Cloud Sync?

Cloud sync allows you to keep the same files updated across multiple devices—PCs, smartphones, tablets, and more.
When you edit a file on one device, the changes automatically appear everywhere else.
This eliminates the need for USB drives, email attachments, or manual transfers.

Different services offer different strengths: privacy, encryption, backup, multi-cloud integration, self-hosting, enterprise governance, or unlimited media storage.
This site organizes all major options by use case so you can quickly find the best match for your workflow.
