How Binary Encoding Works
Every character in text has a numeric value in the ASCII or Unicode table. For example, the letter "A" is 65 in decimal, which is 01000001 in binary. This tool converts each character to its binary, hex, octal, and decimal representations.
Understanding Number Bases
Binary (base-2) uses only 0 and 1. Hexadecimal (base-16) uses 0-9 and A-F. Octal (base-8) uses 0-7. Decimal (base-10) is the standard number system. Each base is useful in different computing contexts: binary for low-level hardware, hex for memory addresses and colors, octal for Unix file permissions.
Common Uses
Developers use binary converters for debugging data encoding issues, understanding character sets, working with network protocols, and learning about how computers represent text internally. This tool supports full Unicode text, not just ASCII.
