File Upload as a Service: Best Options in 2026
File upload as a service (FUaaS) means using a third-party platform to handle file uploads, storage, and sharing — without building your own infrastructure. In 2026 there are two main categories: consumer services (no account, instant sharing) and developer APIs (programmatic upload and storage).
