About Base64

Base64 is an encoding system that converts binary data into ASCII text. It uses 64 different characters (A-Z, a-z, 0-9, +, /) to represent data.

Common uses:

  • Transmitting binary data via email
  • Encoding images in HTML/CSS (Data URIs)
  • Storing data in JSON or XML
  • HTTP Basic Authentication

Note: Base64 is NOT an encryption method. Encoded data can be easily decoded. Do not use Base64 to protect sensitive data.
