Encode text into 8-bit binary — or decode binary back into readable text.

💻 How to Use This Binary Converter

  1. 1.Type or paste your input. Ordinary text if you want binary, or 0s and 1s if you want text back.
  2. 2.Pick a direction. "Text → Binary" encodes every character as one 8-bit byte; "Binary → Text" decodes it back.
  3. 3.Mind the validation. If binary is malformed — a stray digit, or a length that is not a multiple of 8 — the tool explains exactly what is wrong instead of guessing.
  4. 4.Copy or swap. Copy the result anywhere, or swap it back into the input box to convert in the other direction.

❓ FAQ

How does text become binary?

Every character has a number code (its ASCII / Unicode value). This converter writes each code as an 8-bit binary number — for example "H" is 72, which is 01001000 in binary — and separates the bytes with spaces.

Why did my binary fail to decode?

Binary input must contain only 0s, 1s and spaces, and the total number of digits must divide evenly by 8, because each character is exactly one 8-bit byte. The tool checks both rules and tells you in plain words which one broke.

Can it handle emojis and non-English letters?

Yes — characters beyond the basic Latin range are encoded as 16-bit or 32-bit groups (whole bytes), and decoding reverses them the same way, so accented letters and most symbols round-trip correctly.

Is this binary converter free?

Yes — 100% free with no sign-up. Conversion happens entirely in your browser; your text is never uploaded, stored, or sent anywhere.
