Binary Code Translator
Convert text to 8-bit binary and decode binary back to text. Uses standard UTF-8 encoding, so every character — including accents and emoji — round-trips correctly.

Frequently Asked Questions
- How do I convert text to binary?
- Type or paste your text into the input box. Each character is converted to its 8-bit binary byte, and the bytes are shown separated by spaces so they are easy to read and copy.
- How do I convert binary back to text?
- Paste binary made up of 8-digit groups separated by spaces or new lines. The tool validates that every group is exactly eight binary digits, then decodes the bytes back to text. Invalid groups are reported instead of guessed at.
- What encoding does the translator use?
- UTF-8. Plain English letters, digits, and punctuation each become one byte, exactly matching their ASCII binary values. Accented letters, symbols, and emoji become two to four bytes, which is why some characters produce more than one 8-bit group.
- Why does one character sometimes produce several bytes?
- Characters outside the basic ASCII range (like é, ñ, or emoji) cannot fit in a single byte, so UTF-8 spreads them across multiple bytes. When you decode those bytes, the original character comes back intact.
- Is my text sent to a server?
- No. The conversion runs entirely in your browser using the built-in TextEncoder and TextDecoder APIs — nothing you type ever leaves your device.
