Text to binary and back, in one tool
Converts plain text into its binary (base-2) representation, one 8-bit byte per character using UTF-8 encoding, with each byte separated by a space for readability. Click the mode button to flip direction and paste space-separated binary bytes back into readable text instead - the same tool handles both directions without needing to navigate anywhere else.
Why UTF-8 encoding matters here
Computers don't store letters directly - they store numbers, and UTF-8 is the standard rule for which number (or sequence of numbers) represents which character. Basic ASCII characters (standard English letters, digits, and punctuation) each take exactly one byte, which is why a short English word produces one clean 8-bit group per character.
Why some characters produce more than one 8-bit group
Characters outside the basic ASCII range - accented letters, non-Latin scripts like Bengali or Arabic, and emoji - need more than one byte to represent under UTF-8, typically 2 to 4 bytes per character. That means a single visible character you typed can expand into 2-4 separate 8-bit binary groups in the output, which is expected behavior, not an error.
Where this is genuinely useful
Understanding exactly how text is represented at the byte level for a programming or computer-science context, decoding a binary string you've encountered elsewhere to see what it actually says, or generating a binary representation of a word for a worksheet, puzzle, or demonstration.
