Binary to Text Converter
Convert text to UTF-8 binary bytes and complete 8-bit groups back to text.
This tool runs entirely in your browser. Your files are never uploaded to a server.
What this tool does
Choose Encode or Decode, paste a value, and copy the result that updates immediately.
Encoding standard
Each UTF-8 byte is shown as exactly eight zero-or-one digits, separated by spaces for copying and visual inspection.
How data is represented
Unicode characters may occupy several bytes. The converter works with UTF-8 bytes rather than JavaScript character code units, so emoji round trips correctly.
Example
A becomes 01000001, while an emoji produces four additional byte groups. Decoding joins all groups before validating UTF-8.
Input validation
Binary input may contain whitespace but must otherwise use only 0 and 1 and contain a whole number of eight-bit bytes.
Limitations
The output represents UTF-8 text bytes, not arbitrary machine words, floating-point values, file contents or a number-base conversion.
Privacy
All byte conversion runs locally in your browser; input and output are never uploaded by this tool.
