Why Use Base64 Images?
- Reduce HTTP Requests: Embedding small images directly into HTML or CSS reduces the number of server requests.
- Portability: Single-file HTML documents (like email templates) can contain all necessary images.
- Database Storage: Store images directly in text fields in databases (though often not recommended for large files).
