About Hexadecimal Encoding
Hexadecimal is a base-16 number system that uses digits 0-9 and letters A-F. In text encoding, each character is represented by two hexadecimal digits (one byte). For example, 'A' becomes 41, and 'Z' becomes 5A. Hex is more compact and human-readable than binary, making it popular for representing data in programming and debugging.
Output Format Options

- Space-separated: Add spaces between bytes for easier reading (48 65 6c 6c 6f)
- 0x prefix: Add 0x prefix to each byte for programming language compatibility (0x48 0x65 0x6c 0x6c 0x6f)
