Understanding Base64 Encoding

Base64 is a standard encoding scheme that transforms binary data into a sequence of printable ASCII characters. It is commonly used to safely transmit data across networks that are designed to handle only text.

Common Applications

  • Data URIs: Embedding small images or fonts directly into HTML/CSS files.
  • API Payloads: Safely sending complex string data or files within JSON payloads.
  • Not Encryption: Remember, encoding is not encryption! It provides data integrity, not security.
