How It Works

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is designed to carry data stored in binary formats across channels that only reliably support text content.

Common Uses:

  • Embedding images directly into HTML or CSS files.
  • Encoding binary data for email attachments (MIME).
  • Storing complex data in URLs.
