About the Text to Hex
This tool converts text into Hexadecimal codes. Every character on a computer has a numeric code point — the letter A is 65, a space is 32 — and this converter shows those codes in Hexadecimal. Type on the left and the result appears instantly.
Worked example. Each character becomes its code point in Hexadecimal. The letter H is code point 72, which is 48, and i is 105, which is 69 — so "Hi" becomes "48 69".
The codes are separated by spaces, one per character, so you can read them straight across. This is the standard way to inspect or hand-build text at the byte level — useful when debugging an encoding, reading a hex dump, or writing an escape sequence. Everything runs in your browser, so nothing you type is uploaded. For the opposite direction use the Hexadecimal to Text converter, and see also text to binary and the ASCII converter.
