Frequently Asked Questions
What is hexadecimal encoding?
Hexadecimal (hex) is a base-16 number system using digits 0-9 and letters A-F. Each hex digit represents 4 bits, making it compact for representing binary data. Two hex digits represent one byte (ASCII character).
How do I convert hex to ASCII?
Each pair of hex digits converts to one ASCII character. For example, '48656C6C6F' converts to 'Hello' (48→H, 65→e, 6C→l, 6C→l, 6F→o). Our tool automatically handles the conversion as you paste hex values.
What's the difference between hex and ASCII?
ASCII is a character encoding standard where each letter or symbol has a numeric value (0-127). Hexadecimal is a numbering system to represent those values. Hex is often used to display ASCII values in a compact, readable format.
Can I convert ASCII back to hex?
Yes, the conversion works both ways. Our tool can encode ASCII text to hexadecimal format. Simply input your text and get the hex representation.
