Text to Binary / Hex Converter

Each character in the text is converted to its Unicode code point (a number), which is then expressed as an 8-bit binary string. For example, the letter 'A' has code point 65, which is 01000001 in binary.

Hexadecimal (hex) is a base-16 number system using digits 0-9 and letters A-F. Each hex digit represents 4 bits, so one byte (8 bits) is represented by two hex characters. For example, the letter 'A' (65 decimal) is 41 in hex.

This tool handles standard ASCII characters (0-255) perfectly. For extended Unicode characters beyond the basic ASCII range, the binary representation will use more than 8 bits to represent the full code point.

The binary output shows each character as a space-separated 8-bit binary string. For example, 'Hi' becomes '01001000 01101001'. The Hex output uses space-separated two-character hex codes.

Switch to 'Binary → Text' mode and enter space-separated 8-bit binary strings. The tool will convert each binary value back to its corresponding character. Each group of 8 digits represents one character.
