Convert text to binary code and binary to text. Perfect for encoding messages, learning binary representation, and data processing.
Three: space-separated 8-bit groups (the default), one continuous string of bits, or one byte per line. Switching format re-converts your input immediately, and the bit counter shows the total number of 0s and 1s.
Switch to Binary to Text mode and paste your bits. Separators such as spaces are optional, because everything except 0 and 1 is stripped before decoding, so both grouped and continuous input work.
If the total number of bits is not a multiple of 8, the tool returns an error asking for complete 8-bit groups. Bytes that decode outside the ASCII range become a question mark in the output.
No. Each character is encoded as a single 8-bit ASCII byte, which covers standard English letters, digits, and punctuation. Accented characters and other scripts fall outside this range.
Only the page loads from the network. Encoding and decoding run locally in your browser, and the built-in ASCII reference table can help you verify results by hand.
