About Binary / Hex / ASCII Converter
Converts text between plain text, binary, hexadecimal, and decimal byte values (UTF-8, so accented letters, other scripts and emoji work), keeping all four representations in sync as you edit any one of them.
Type or paste into any of the four fields — text, binary, hex, or decimal — and the other three update automatically to match.
Editing the binary or hex field directly is a genuinely useful way to understand how character encoding actually works, rather than just converting text one direction and moving on.
