Text to Binary FAQ

How do I convert text to binary?

Type or paste your text above. Each character becomes one or more 8-bit bytes using UTF-8: “Hi” turns into 01001000 01101001. Copy or download the result with one click.

How many bits is one character in binary?

Basic English letters are one byte (8 bits). Chinese characters take 3 bytes (24 bits) and most emoji take 4 bytes (32 bits) in UTF-8. The status line above the result always shows the exact byte count.

Can I convert Chinese text or emoji to binary?

Yes. The converter uses UTF-8 by default, so 你好, 👋 and any other Unicode character convert correctly — each becomes multiple 8-bit bytes.
