Frequently Asked Questions

How does text to binary conversion work?

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.

What is hexadecimal representation?

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.

Can this tool handle Unicode characters?

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.

What format is the binary output?

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.

How do I convert binary back to text?

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.
