How does text become binary?

Every character in your text is first converted to its underlying byte value using UTF-8 encoding (the standard used across the modern web), and each byte is then written out as an 8-digit binary number. For example, the letter "A" has the UTF-8 byte value 65, which is 01000001 in binary. Characters outside basic English (like accented letters or emoji) may use more than one byte in UTF-8, so they'll produce more than 8 binary digits each - that's expected and correct.

About Text to Binary Converter

Text to Binary Converter turns plain text into its binary (base-2) representation instantly as you type. It correctly handles full Unicode text, not just basic English letters, by converting each character to its real UTF-8 byte values before converting those bytes to binary. Choose how the 8-bit bytes are separated - spaces, commas, or none - then copy or download the result. Everything runs locally in your browser, so nothing you type is sent to a server.
