Binary Translator: Text to Binary and Back

Each character is encoded as one or more UTF-8 bytes, and every byte is written as eight binary digits. The letter A is byte 65, which is 01000001. Plain ASCII characters use a single byte, while accented letters and emoji spread across two to four bytes.

In Text to binary mode you can put a Space between each eight-bit byte or set None to run them together. Space makes long output easier to read; None gives a compact stream. When decoding, any spaces are ignored, so the choice only affects how the binary looks.

Yes. Because encoding uses UTF-8, a character such as an e with an acute accent becomes the two bytes 11000011 10101001, and it decodes back to the exact original. Emoji work the same way across their three or four bytes.

Groups of eight bits made only of 0s and 1s. Spaces, tabs and line breaks between groups are stripped first, so both 01001000 01101001 and 0100100001101001 decode to the same text. The total digit count must be a multiple of eight.

Yes. All whitespace is removed before decoding, so a solid block of bits works as long as its length divides evenly by eight. This is handy when you copy binary that lost its spacing along the way.

The input holds a character other than 0 or 1, or the digit count is not a multiple of eight. Delete any stray letters or symbols and make sure each byte carries exactly eight bits before decoding.

ASCII covers the first 128 code points, and UTF-8 encodes each of them as one byte with a leading 0. So for ordinary English text the binary you get here matches an ASCII table exactly, one byte per character.

There is no fixed cap. The work happens in your browser, so the practical ceiling is your device memory. Very long text or binary translates almost instantly.

No. The translation happens entirely in your browser, so whatever you type or paste never leaves your device.
