How Binary Byte Encoding Works
Eight binary digits (bits) represent one byte (0–255). When converting text to binary, each character is first encoded to UTF-8 bytes, then each byte is displayed as 8 binary digits.
Example: "Hi" → 01001000 01101001 (2 bytes, 16 bits total).
Multi-byte: "ü" → 11000011 10111100 (2 UTF-8 bytes). "🙂" → 4 bytes (32 bits).
7-bit display: Useful for pure ASCII characters where the high bit is always 0. Select "7-bit" in options for compact ASCII representation.
Binary vs. Number Base Conversion
This page converts text bytes to binary groups. For mathematical binary conversion (e.g. 42 → 101010), use the Number Base Converter.
