How to convert text to binary (and back)
Encode text as binary octets, or decode binary back into text, using standard UTF-8 byte encoding.
How the encoding works
Text is first encoded as UTF-8 bytes, then each byte is shown as an 8-digit binary number, separated by spaces. This means any Unicode text — accented letters, emoji, non-Latin scripts — round-trips correctly, since it works at the byte level rather than assuming plain ASCII.
How to use it
- Choose "Text to Binary" or "Binary to Text".
- Type text, or paste binary octets separated by spaces.
- Copy the result once it looks right.
Common uses
Useful for teaching how computers represent characters, checking byte-level encoding of a short string, or decoding binary snippets found in puzzles, homework, or low-level debugging output.

FAQ
Why 8 digits per character?
Because text is encoded as UTF-8 bytes first, and a byte is always 8 bits — this is standard binary/ASCII-style representation.
Does it support accents and emoji?
Yes. Since encoding works on UTF-8 bytes rather than assuming one byte per character, any Unicode character round-trips correctly (some, like emoji, take more than one byte).
What happens if I paste invalid binary?
Any group that isn't made only of 0s and 1s (up to 8 digits) is reported as invalid instead of silently producing a wrong or partial result.
