What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in ASCII string format.
Common use cases:
• Email attachments (MIME)
• API authentication (Basic Auth)
• Data URIs in web pages
• Storing binary data in JSON/XML
• Encoding images in HTML/CSS
Size overhead:
Base64 increases size by approximately 33% (3 bytes → 4 ASCII characters).
Text: "Hello" → "SGVsbG8="
JSON: {"key":"value"} → "eyJrZXkiOiJ2YWx1ZSJ9"
Basic Auth: user:pass → "dXNlcjpwYXNz"
Empty string: "" → ""
Single char: "A" → "QQ=="
Two chars: "AB" → "QUI="
