About Base64 Encoding

Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. It's commonly used for transmitting data over media that is designed for text only, such as email and HTML forms.

Common uses include:

  • Embedding image data in HTML or CSS
  • Storing complex data in JSON
  • Encoding binary data to be included in URL parameters
  • Basic authentication credentials in HTTP headers
