What Is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data as an ASCII string. It's commonly used to embed images directly in HTML, CSS, or JSON without needing separate image files. This is useful for small icons, email templates, and reducing HTTP requests. Note that Base64 strings are typically ~33% larger than the original binary data.
