What is ASCII to Hex Conversion?

ASCII to Hex conversion transforms human-readable text into its hexadecimal (base-16) representation. Each character in ASCII has a corresponding numeric value, which can be expressed in hexadecimal format using digits 0-9 and letters A-F.

How Does It Work?

Every character you type on a keyboard has an ASCII code - a number between 0 and 127. When converting to hexadecimal:

  • 'A' = ASCII 65 = Hex 41
  • 'a' = ASCII 97 = Hex 61
  • '0' = ASCII 48 = Hex 30
  • Space = ASCII 32 = Hex 20

Example Conversion

Text Hex (with spaces) Hex (no spaces)
Hello 48 65 6C 6C 6F 48656C6C6F
World 57 6F 72 6C 64 576F726C64
