About Hexadecimal Encoding

Hexadecimal (or "hex") is a base-16 number system that uses 16 distinct symbols: the numbers 0-9 and the letters A-F (or a-f). In computing, hexadecimal is commonly used as a more human-friendly way to represent binary data, where each hex digit represents 4 bits (half a byte).

Common Uses for Hex Conversion

• Programming and debugging - Viewing binary data in a more readable format
• Web development - Creating color codes, HTML entities, or CSS escape sequences
• Data encoding - Representing binary data in text format
• Network protocols - Analyzing packet data
• Cryptography - Working with hashes and encrypted data
• Educational purposes - Learning about different number systems

Hex Format Options Explained

• Plain - No separators (e.g., 48656C6C6F)
• Space-separated - Spaces between bytes (e.g., 48 65 6C 6C 6F)
• Comma-separated - Commas between bytes (e.g., 48,65,6C,6C,6F)
• 0x Prefix - C-style hex notation (e.g., 0x48 0x65 0x6C 0x6C 0x6F)
• HTML Entities - HTML character references (e.g., Hello)
• CSS Escape - CSS unicode escapes (e.g., \48 \65 \6C \6C \6F)
