What is Base64?

Base64 is a binary-to-text encoding scheme. It represents binary data in an ASCII string format by translating it into a radix-64 representation. It is commonly used to embed image data directly into HTML/CSS or to transmit complex data over media that are designed to deal with textual data.

Common Use Cases:

  • Embedding small images (Data URIs) in CSS.
  • Encoding API credentials (Basic Auth).
  • Transmitting binary files via Email (MIME).
  • Hiding simple text data from casual view (not encryption!).
