What is Base64?

Base64 is an encoding scheme that converts binary data (or plain text) into a printable string format consisting of 64 characters (A-Z, a-z, 0-9, +, and /). It is heavily used in email protocols and web APIs to ensure data safely passes through systems that only support text.

Encoding vs Encryption

Warning: Base64 is not encryption! It is simply an encoding format. Anyone can instantly decode a Base64 string back into plain text. Never use Base64 to secure passwords or sensitive data.
