About Hex Encoder
Hexadecimal is base-16 numbering using 0-9 and A-F. It is commonly used in computing for color codes, memory addresses, and representing binary data in a more compact form. Each hex digit represents 4 bits (half a byte).
How It Works
Each character is converted to its ASCII value, then to hexadecimal (two digits). The process reverses to decode hex back to text. For example, "A" becomes "41" in hex.
Common Uses
- Programming and development
- Color codes (CSS/web design)
