How to Convert Between Hexadecimal and ASCII?
Converting between hexadecimal and ASCII is essential for developers, network engineers, and cybersecurity professionals. Hexadecimal (hex) is a base-16 numbering system often used to represent binary data in a more readable format. ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numerical values to characters.
To convert from hex to ASCII, each pair of hexadecimal digits represents one byte (8 bits) which corresponds to an ASCII character. For example, '48' in hex equals 72 in decimal, which is the ASCII code for the letter 'H'. Conversely, to convert ASCII to hex, each character is converted to its ASCII decimal value, then to hexadecimal representation.
This tool handles both directions automatically - simply select your input format, enter your data, and get instant results. Spaces and case are handled automatically.
