About Base64 Encoding

Base64 is a binary-to-text encoding scheme that represents binary data in ASCII format. It's commonly used for encoding data in email, web applications, and data storage.

Common Use Cases:

  • • Email attachments (MIME)
  • • Data URLs in web pages
  • • API authentication tokens
  • • Storing binary data in text formats
  • • URL-safe data transmission

Encoding Types:

  • • Standard: Uses +, /, and = characters
  • • URL Safe: Uses -, _, no padding
  • • Increases data size by ~33%
  • • Reversible encoding process
  • • Case-sensitive format
