About Multi-Base Conversion

This tool converts between hexadecimal, decimal, binary, and ASCII representations. When you enter a value in any field, the other fields update automatically.

Features:

  • Enter a hexadecimal value (with or without '0x' prefix)
  • Enter a decimal value
  • Enter a binary value (single or multi-byte sequence)
  • Enter an ASCII string (single character or longer string)
  • Enter multi-byte hex (e.g., "48 65 6C 6C 6F" or "0x48 0x65")
  • All fields update in real-time as you type

Example:

  • Hex: 0x41 → Decimal: 65 → Binary: 1000001 → ASCII: A → Hex Long: 41
  • ASCII: "Hi" → Binary: 01001000 01101001 → Hex Long: 48 69
  • Hex Long: 48 65 6C 6C 6F → ASCII: "Hello"
