About this tool
Text is encoded as UTF-8 first, then each byte is written as 8 bits, space-separated — so a plain ASCII character like A becomes a single byte (01000001), while an emoji or accented letter becomes multiple bytes, exactly as it would be stored in a UTF-8 text file. Converting binary back to text expects the same format: 8-bit groups separated by spaces or line breaks.
