What does this tool do?

Letters, accents, emoji and symbols are encoded exactly as they would be in a UTF-8 file or network message. ASCII characters take one byte, most European letters two, most Asian scripts three and emoji four.

Everything runs in your browser, so nothing you enter is uploaded or stored.
