When Should You Use Base64 Encoding?

While Base64 is incredibly useful, it increases file size by about 33%. It is best used for small images (icons, logos) in CSS, embedding fonts, or passing complex data through JSON APIs. For large photographic images, traditional image hosting is recommended to maintain website loading speed.
