How does text to binary conversion work?

Each character is converted to its UTF-8 byte representation, then each byte is shown as an 8-bit binary number. For example, 'A' (byte 65) becomes 01000001.

Does it support Unicode and emoji?

Yes. The tool uses UTF-8 encoding, so multi-byte characters like accented letters and emoji are correctly converted to multiple binary bytes.

What separator options are available?

Space (default), no separator, comma, or newline. Separators only apply in encode mode — decode mode automatically detects byte boundaries.

Is my text sent to a server?

No. All conversion happens in your browser. Your text never leaves your device.

How to Use

Select encode (Text → Code) or decode (Code → Text) direction, pick a format (binary, hex, octal, decimal), and type or paste your input. Output updates in real time. Use Swap to quickly reverse the conversion.

How It Works

Each character is converted to its UTF-8 byte sequence, then each byte is represented in the chosen base. For example, 'A' (byte 65) becomes 01000001 in binary, 41 in hex, 101 in octal, or 65 in decimal.
