What is Base64?

Base64 is an encoding scheme that converts binary data into ASCII text format. It's commonly used for:

  • Embedding images in HTML/CSS (data URIs)
  • Encoding credentials in HTTP headers
  • Transmitting binary data over text-based protocols (email, JSON)
  • Storing complex data in URLs or cookies
Examples:
Original Text:
Hello World!
Base64 Encoded:
SGVsbG8gV29ybGQh
Original Text:
user:password123
Base64 Encoded:
dXNlcjpwYXNzd29yZDEyMw==
Note:

Base64 encoding increases the size of data by approximately 33%. It is NOT encryption and should not be used for security purposes.
