When hex comes up
Hexadecimal encoding shows up in a lot of developer contexts: color codes in CSS, memory addresses in debuggers, byte sequences in network protocols, and hash values from cryptographic functions. When you need to see the hex representation of a plain text string — to inspect its byte values, construct a protocol message, or verify an encoding — this tool gives you the conversion in both directions.
String to hex and back
Each character in the input is converted to its two-digit hexadecimal byte value, separated by spaces. For example, the letter A becomes 41, and Hello becomes 48 65 6c 6c 6f. The Hex to String button reverses the process — paste a space-separated hex sequence and get the decoded text back.
