Type your text, and the tool converts it to hexadecimal byte values — paste hex in decode mode to convert it back to text.
Hexadecimal (hex) uses base-16 to represent data. Each character's ASCII value is converted to a 2-digit hex number (0-9, A-F).
Hex is compact and widely used in computing. Two hex digits represent one byte, making it efficient for displaying binary data.
Enter hex values (with or without spaces) and the tool will convert each hex pair back to its ASCII character.
