Handling file uploads involves server-side processing. Typically, the server-side code receives the uploaded file(s), performs any necessary validation or manipulation, and stores the file(s) on the server's file system or in a database. Various programming languages, frameworks, and libraries provide APIs and utilities to handle file uploads securely and efficiently. It's important to consider security measures when dealing with file uploads. This includes checking file extensions, limiting file sizes, validating file formats, and preventing unauthorized access to uploaded files.
