Base64 Encoding

  • • Converts binary data to ASCII text representation
  • • Uses 64 printable characters (A-Z, a-z, 0-9, +, /)
  • • Safe for transmission over text-based protocols
  • • Increases data size by approximately 33%
  • • Widely used in email, web, and data storage
  • • Padding with = characters for proper alignment

Use Cases

  • • Email attachment encoding and transmission
  • • Web API data encoding for JSON payloads
  • • Image embedding in HTML and CSS files
  • • Database storage of binary data
  • • URL-safe data transmission parameters
  • • Configuration file binary data storage
