About Base64 Encoding

What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It encodes every 3 bytes of binary data into 4 ASCII characters.

Example:
"Hello" → "SGVsbG8="

Common Uses:

  • • Embedding images in HTML/CSS
  • • Sending binary data over text protocols
  • • Encoding email attachments
  • • Storing binary data in JSON/XML
  • • Basic authentication headers
