# Understanding Base64 Encoding & Decoding

Base64 is a binary-to-text encoding scheme used to represent binary data (like images or files) in an ASCII string format. It is essential for transmitting data over protocols that are designed to deal with text, such as Email (SMTP) or HTTP.

Our tool offers a real-time solution for developers:

  • Encode: Convert plain text or credentials into Base64 strings for use in Basic Authentication headers.
  • Decode: Revert Base64 strings back to their original readable format to inspect the payload.
