Base64 Information

What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data in ASCII string format. It's commonly used for:

  • • Email attachments (MIME)
  • • Data URLs in HTML/CSS
  • • API authentication tokens
  • • Storing binary data in text formats

Format Options

  • • Standard: Uses +, /, and = characters
  • • URL-safe: Uses -, _, and optionally no padding
  • • No padding: Removes trailing = characters
