Binary Translator
Convert text to binary code and binary back to text — full UTF-8 support, 8-bit grouping, instant results.
Text and binary, both ways
Binary is the language of computers: every letter, digit and symbol is stored as a pattern of 0s and 1s. This translator shows that mapping clearly — type a word to see its binary, or paste binary to read the hidden message. It's a favourite for students learning how encoding works, and for puzzles and geeky messages.
How the encoding works
Text is first encoded to UTF-8 bytes, then each byte is shown as 8 bits.
Plain English letters map to a single byte each (for example "A" is
01000001), while emoji and many accented characters use
several bytes. Decoding reverses the process, reading 8-bit groups back
into characters.
Tips
- Keep groups at 8 bits and separate them with spaces when decoding.
- Use Swap to flip direction and feed the result straight back in.
- UTF-8 safe: non-English text round-trips correctly.
Frequently asked questions
How does text convert to binary?
Each character is encoded as UTF-8 bytes, and every byte is written as 8 binary digits (bits). The byte groups are separated by spaces so the result is easy to read and convert back.
How do I convert binary back to text?
Switch the direction to 'Binary → Text' and paste your binary. Separate each 8-bit group with a space. The tool decodes the bytes as UTF-8, so accented letters and emoji come back correctly.
What if my binary isn't valid?
If the input contains anything other than 0s, 1s and spaces, the tool shows a short error message instead of producing garbage. Make sure each group is 8 bits.
Is it private?
Yes. Conversion happens entirely in your browser; nothing is uploaded.
