Text to Hex
This free text to hex converter turns plain text into equivalent hexadecimal values. It works for ASCII and Unicode input, producing both space-separated and continuous hex output so you can use the result anywhere — from learning exercises to real protocol work.
How Text Is Converted to Hex
Every character in your text is stored by the computer as a numeric code. Converting text to hex means taking each character's code, writing it as hexadecimal, and joining the results. In the classic ASCII encoding, the letter A has the code 65, which is exactly 41 in hex.
For the default example Hello, World!, the conversion produces 48 65 6C 6C 6F ... 21, one hex pair per character. The space-separated view keeps each byte readable, while the continuous view gives you a single string ready to paste into code.
- Type or paste any text into the input box.
- The converter maps every character to its hex code.
- Copy either the spaced or continuous hex output.
- Feed the hex string to a hex to text converter to reverse it.
