What is Base64 encoding used for?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is primarily used to transmit data over networks or embed files within formats that only support text. Common use cases include embedding image files directly inside HTML or CSS documents (as Data URIs), encoding JSON Web Tokens (JWTs), and safely transmitting sensitive data through XML protocols or email systems.
Security Note: Base64 is an encoding algorithm, not encryption. It is incredibly easy to decode back to plain text. You should never use Base64 to hide passwords or secure sensitive data without first applying standard encryption protocols.
