How text becomes binary
Each character you type is stored as one or more bytes using UTF-8, and each byte is eight bits — a sequence of eight 0s and 1s. This tool encodes your text and shows you exactly those bytes, separated by spaces so they are easy to read.
How to convert text to binary
Type or paste your text into the box above and the binary appears instantly. Plain English, punctuation, accented letters and emoji are all supported, because the text is encoded as UTF-8 before being written out in binary.
Frequently asked questions
- Is my text uploaded to a server?
- No. The conversion runs entirely in your browser using your device — your text never leaves your computer and is never uploaded to us or anyone else.
- Why are some characters more than eight digits?
- ASCII characters fit in a single 8-bit byte, but accented letters, symbols and emoji use several UTF-8 bytes — so they appear as several 8-bit groups.
- Can I convert the binary back to text?
- Yes — paste the output into our Binary to Text converter to decode it again. The two tools are exact inverses.
