Text to Binary Converter

About Text to Binary Conversion

This tool converts text characters to their binary, octal, decimal, and hexadecimal numeric representations based on their Unicode code points. Each character is converted independently. In binary mode, each character becomes an 8-bit binary number (or more for extended Unicode). All processing happens in your browser -- no data is sent to any server.

How It Works

• Binary (Base 2): Uses only digits 0 and 1. Each character is represented as an 8-bit binary number padded with leading zeros.
• Octal (Base 8): Uses digits 0-7. Each character code is expressed in octal notation.
• Decimal (Base 10): The standard numeric code point value for each character.
• Hexadecimal (Base 16): Uses digits 0-9 and letters A-F. Commonly used in programming and web colors.
