What Is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data using 64 printable ASCII characters (A-Z, a-z, 0-9, +, /). It's widely used to encode binary data for transmission in text-based systems.

Common Uses of Base64

  • Email: Encoding attachments in MIME email format
  • Web: Embedding images as data URLs in HTML/CSS
  • APIs: Encoding credentials in HTTP Basic Authentication
  • JWT: JSON Web Token encoding
  • Storage: Storing binary data in text fields

Base64 vs Encryption

Base64 is NOT encryption. It's an encoding scheme that is easily reversible. Never use Base64 alone to secure sensitive data. For security, use proper encryption algorithms like AES or RSA.
