Hex to Binary Converter Online Tool

This online hex to binary converter tool helps you to convert one input hex number (base 16) into a binary number (base 2).

Hex numeral system (also called hexadecimal) has 16 digits, include (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) just like decimal numeral system, plus (a, b, e, d, e, f) 6 additional characters. Which means it's is a number system of base 16. Since Hex numeral system can represent any binary string in a readable way, It is widely used in computer science. The SHA256 hash string is often appears as Hex style string, the Color System used in HTML is also be written down as Hex number, from #000000 (pure black) to #FFFFFF (pure white).
