Binary Code Translator

Translate text to binary and back.

Free online binary code translator

Translate text into binary code or decode binary back into readable text in an instant. This binary translator is fully UTF-8 safe, so plain letters, accented characters, non-Latin scripts, and even emoji convert without corruption. It is perfect for computer-science homework, exploring how computers store characters, sending playful hidden messages, or debugging low-level data. Everything runs live in your browser as you type.

How to use the binary translator

  1. Pick Text to Binary to encode, or Binary to Text to decode.
  2. Type or paste your content into the input box on the left.
  3. Read the converted result in the output box — it updates automatically.
  4. In text mode, choose whether bytes are separated by a Space or None.
  5. Use Swap for a quick round trip, Copy result to grab the output, or Clear to reset.

How text becomes binary

Each character is first encoded as one or more UTF-8 bytes, and every byte is written as an 8-bit binary number from 00000000 to 11111111. A capital A is 01000001, which is decimal 65. Multi-byte characters like emoji simply produce several 8-bit groups in a row. Decoding reverses the process: the digits are split into 8-bit bytes and turned back into text.

Related conversion tools

Binary is just base-2. To see the same value in octal, decimal, or hexadecimal, try the number base converter. If you need to move binary data through text-only channels instead, the Base64 encoder / decoder is a more compact, transport-friendly option. All of these tools run entirely client-side, so your data never leaves your device.

Frequently asked questions

How do I convert text to binary?

Choose Text to Binary, then type or paste your text. Each character is encoded as UTF-8 bytes and every byte becomes an 8-bit binary number, so the result is a series of 0s and 1s. By default the bytes are separated by a space for readability, but you can switch the separator to None for one continuous string.

How do I convert binary back to text?

Switch to Binary to Text and paste your binary code. The tool ignores anything that is not a 0, 1, or space, splits the digits into 8-bit groups, and decodes those bytes back to readable UTF-8 text. If a group is not exactly 8 bits, you will see a clear message instead of a broken result.

Does it support emoji and accented characters?

Yes. Conversion uses UTF-8, so emoji, accented letters, and non-Latin scripts round-trip correctly. These characters use more than one byte, which means they map to several 8-bit binary groups rather than just one.

What if my binary has no spaces?

That is fine. When the input contains no spaces, the tool chunks the digits into groups of 8 from the start. Just make sure the total number of binary digits is a multiple of 8, otherwise the last group will be incomplete and flagged as an error.

Is my data sent to a server?

No. All translation happens locally in your browser with JavaScript. Nothing you type is uploaded, logged, or stored, so it is safe to convert private text.
