What binary format does this tool accept?

The tool accepts binary strings made of 0s and 1s. Bytes can be space-separated (01001000 01101001) or written as a continuous stream (0100100001101001). Non-binary characters are flagged as errors.

How does binary-to-text decoding work?

Each group of 8 bits (one byte) is converted to its decimal value, then mapped to the corresponding ASCII or Unicode character. For example, 01001000 = 72 = "H".

Can it decode non-ASCII characters?

Yes. If the binary represents valid UTF-8 byte sequences, the tool will decode them correctly to Unicode characters.

What if my binary string is not a multiple of 8 bits?

The tool pads incomplete bytes with leading zeros and notes the padding. For best results use complete 8-bit bytes.

What is the difference between the output formats?

Text shows the character representation. Decimal shows the numeric value of each byte (0-255). Hex shows each byte as two hexadecimal digits. Octal shows each byte in base-8 notation.
