About Base64 Encoding

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used for encoding data in email systems, URLs, and web applications where binary data needs to be transmitted over text-based protocols.

  • Character Set: A-Z, a-z, 0-9, +, / (with = for padding)
  • Encoding Ratio: Every 3 bytes become 4 characters (33% size increase)
  • Common Uses: Email attachments, data URLs, API tokens, embedded images
  • Safety: Text-safe for transmission over protocols that may not handle binary data
