About Hexadecimal (Base-16)

The hexadecimal system uses 16 unique symbols: the numbers 0 to 9 and the letters A to F to represent values 10 to 15.

It is widely used in computing because it provides a human-friendly way to represent binary-coded values. Each hex digit corresponds to exactly four binary digits (bits).

How Text to Hex Works

Every character on a computer is represented by a number. The most common standard is ASCII (and its extension, UTF-8). For example, 'H' is 72, 'e' is 101, and '!' is 33.

This tool takes each character, finds its numeric code, and converts that number into its two-digit hexadecimal equivalent. 'H' (72) becomes 48, and 'e' (101) becomes 65.
