Binary to Text Converter

Frequently Asked Questions

How many bits is the letter 'A'?

Eight bits: 01000001. This matches UTF-8's single-byte encoding for the ASCII range (codepoints below 128), since this tool encodes one byte per character.

What is '01010101010100100100100' as text?

It depends on how you group it. If it is not a multiple of 8, the leftover bits cannot decode to a character. Pad with zeros on the left or check that you have whole bytes.

Can I decode any binary to text?

Only if the binary represents valid text in some encoding. Arbitrary bytes (especially below 32 or above 126) may map to control characters or to undefined positions in non-Unicode encodings.

How It Works

Each text character maps to a single byte code (0-255): ASCII for letters, digits, and punctuation below 128, and the Latin-1 range above that. To go from binary to text, group binary digits into bytes (8-bit chunks), parse each as a number, and convert to the matching character. Going back, take each character's code and format it as 8 binary digits.

Common Mistakes

Skipping the zero-padding to 8 bits. '01000001' and '1000001' both equal 65, but the unpadded form fails when concatenated with the next byte.

Assuming this converter handles multi-byte UTF-8 encoding - it maps one character to exactly one 8-bit byte (0-255), so it is not a general UTF-8 encoder/decoder.

Feeding in characters above code point 255, such as most emoji: they don't fit the tool's fixed 8-bit-per-character scheme and won't round-trip correctly.

Tips and FAQ

Why 8 bits per group? A byte is 8 bits, and ASCII fits in 7 bits with a padding bit. This tool maps each character to one 8-bit byte (0-255) rather than encoding real multi-byte UTF-8.

What separators work when reading binary? Any non-0/1 characters (spaces, dashes, line breaks) between groups are stripped before parsing. Output is always space-separated bytes.

Big-endian or little-endian? Strings are conventionally big-endian (MSB first), which is what this tool uses.
