What is Base64?

Base64 is an encoding scheme that converts binary data into ASCII text. It's commonly used to:

  • Embed images in HTML/CSS (data URLs)
  • Send binary data over text-based protocols (email, JSON)
  • Encode authentication tokens
  • Store binary data in databases or configuration files

Note: Base64 is encoding, not encryption. It doesn't provide security!
