Frequently Asked Questions
What hexadecimal formats does this tool accept?
Enter hex values separated by spaces, commas, or semicolons. You can also use "0x" or "\x" prefixes - the tool strips them automatically. Each pair of hex digits represents one byte. For example, "48 65 6C 6C 6F" and "0x48 0x65 0x6C 0x6C 0x6F" both decode to "Hello".
Why are hex values always two digits?
Two hexadecimal digits represent exactly one byte (8 bits), which maps to values 0 through 255. This covers the full range of ASCII and extended ASCII characters. The hex system uses digits 0 through 9 and letters A through F, where A equals 10 and F equals 15 in decimal.
Can I convert text to hexadecimal?
Yes. Use the "Text to Hex" mode to convert any text string into its hexadecimal byte representation. Each character produces a two-digit hex code that you can use in programming, network protocols, or data analysis.
