File Conversion Service:

Purpose: Converts files from one format to another (e.g., PDF to DOCX, JPG to PNG).

How it Works: Users upload a file to the server. The server processes the file using appropriate conversion libraries or external tools. Once converted, the new file is stored or deleted depend of the user decision, and a download link is provided to the user.

Key Components: File upload mechanism, backend processing logic, file storage, and a download interface.

User Authentication Service:

Purpose: Manages user login, registration, and session management, ensuring only authorized users can access certain features.

How it Works: Users provide credentials (e.g., username/email and password). The system verifies these against stored records. Upon successful authentication, a secure token (e.g., JWT) is issued, which the user includes in subsequent requests to access protected resources.
