Binary code represents every character as a string of 0s and 1s. Computers store text as bytes, and each byte is eight bits; this translator shows the exact binary for any text and decodes binary back into readable characters, using UTF-8 so accented letters and emoji work too.
It is popular with students learning how computers store data, hobbyists making binary puzzles, bracelets or tattoos, and developers debugging encodings. Type text to see its binary, or paste 0s and 1s to decode — everything runs in your browser.
