How It Works
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It works by converting data into groups of 6 bits, each represented by a character from a 64-character alphabet (A-Z, a-z, 0-9, +, /). This tool uses UTF-8 encoding to properly handle international characters.
