Frequently Asked Questions
Hexadecimal (hex) is a base-16 numbering system using digits 0–9 and letters A–F. It's widely used in computing to represent binary data more compactly.
Hex is used for color codes (#FF5733), character encoding, memory addresses, and representing byte data in network protocols.
Those hex values decode to 'Hello' — H=0x48, e=0x65, l=0x6C, l=0x6C, o=0x6F.

About this calculator
Convert hexadecimal values to readable text, or text to hex. Hex is a compact way to write bytes, used in colour codes, memory dumps and network traces.
Paste hex like 48 65 6c 6c 6f and get Hello, or type Hello and get the hex.
How to use it
- Choose Hex → Text or Text → Hex.
- Paste the input.
- Press Convert, then Copy Result.
How it works
Each byte is written with two hex digits (0 to 9 and a to f). 48 hex is 4 × 16 + 8 = 72, the ASCII code of H. So 48 65 6c 6c 6f spells Hello.
Worked example
Examples
| Hello | 48 65 6c 6c 6f |
