About Image Base64 Encoding

Converting images to Base64 strings allows you to embed them directly in HTML, CSS, or JSON without separate image files. This is useful for small icons (under 10KB), email templates, and reducing HTTP requests. The trade-off is a ~33% increase in data size compared to the binary original.
