NewConvert text to binary and binary back to text, with full UTF-8 support.
Frequently Asked Questions
Why does binary-to-text reject my input?
This decoder only accepts complete 8-bit groups made of 0 and 1, separated by spaces or line breaks. A continuous bit stream or 7-bit ASCII-style chunks will fail.
Does it support emoji and accented characters?
Yes. The text side is encoded with TextEncoder and decoded with a UTF-8 TextDecoder, so characters outside plain ASCII become their real UTF-8 byte sequences.
Why do some byte sequences throw an error instead of showing weird characters?
The decoder runs in fatal UTF-8 mode. If the bytes are not valid UTF-8, it raises an error instead of silently replacing them with placeholder characters.
Can I paste one long binary string without spaces?
No. This tool expects one byte per token, such as 01001000 01101001. You need separators so it can tell where one byte ends and the next begins.
Does editing one side automatically update the other?
Yes. Typing in either panel updates the other after a short delay, with a sync guard so the two listeners do not loop forever.
