Base64 Encoder & Decoder
Quickly encode strings into Base64 format or decode Base64 strings back to plain text.
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.
