Hexadecimal (also base 16 or simply hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols **0–9** to represent values 0 to 9, and **A–F** (or alternatively **a–f**) to represent values 10 to 15. In computing, hex is widely used to write byte patterns in a compact form. This tool encodes each character of your text into its constituent UTF-8 bytes and displays them in hex formatting.
