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 transmitting data over media designed to handle text.

Common Use Cases:

  • Embedding images in HTML/CSS (data URLs)
  • Encoding data in JSON or XML
  • Email attachments (MIME)
  • Authentication tokens (JWT)
  • Storing binary data in databases or config files

URL Safe Mode: Uses '-' and '_' instead of '+' and '/' to make the encoded string safe for URLs and filenames.
