Frequently Asked Questions

How many bits is the letter 'A'?

Eight bits: 01000001. In UTF-8, the entire Latin alphabet is a single byte each because the codepoints are below 128.

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 has a codepoint (ASCII for letters and digits, UTF-8 multi-byte for everything else). 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 codepoint 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.

Mixing UTF-8 multi-byte codepoints with single-byte ASCII without consistent byte boundaries.

Forgetting that emoji are 4-byte UTF-8 sequences. Each takes 32 bits, not 8.

Tips and FAQ

Why 8 bits per group? A byte is 8 bits, and ASCII fits in 7 bits with a padding bit. UTF-8 extends with multi-byte sequences whose first byte signals the length.

What separators work? Space, dash, line break, or nothing - the parser handles all four. Output defaults to space-separated bytes.

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