What is Base64?

Base64 is an encoding scheme that converts binary data into ASCII text format. It's commonly used to encode data in URLs, emails, and APIs.

  • Encodes data using 64 characters (A-Z, a-z, 0-9, +, /)
  • Makes binary data safe for text-based systems
  • Increases data size by approximately 33%
  • Used in web development, APIs, and email attachments

Common Use Cases

  • Encoding images for data URIs in CSS/HTML
  • Transmitting binary data over text-based protocols
  • Basic obfuscation of simple data (not encryption!)
  • Encoding credentials for HTTP Basic Authentication
