A Binary Translator converts human-readable text into binary code β the ones and zeros a computer actually stores β and converts that binary back into text. Each character is turned into its UTF-8 byte value and written out in the base you choose: binary (base 2), octal (base 8), decimal (base 10), or hexadecimal (base 16). Type "Hi" and you instantly see 01001000 01101001; paste that binary back in and you get "Hi" again.
The translation is not a lookup table of a few hundred ASCII letters. This tool encodes the full Unicode range through UTF-8, so accented letters, non-Latin scripts, and even emoji translate correctly across two, three, or four bytes each. When you decode, the tool reassembles multi-byte sequences into the original characters and reports a clear error if the byte stream is malformed, rather than producing silent garbage.
Everything runs 100% in your browser. Whether you are decoding a captured binary string, teaching how character encoding works, or checking how a message is represented at the byte level, nothing you paste is uploaded or logged. The translator works offline once the page has loaded, so you can convert sensitive strings without them ever leaving your device.
Pick "Text to Binary" to encode readable text into code, or "Binary to Text" to decode a binary, hex, decimal, or octal string back into characters.
Switch between Binary, Hexadecimal, Decimal, and Octal. The output re-formats instantly, with each byte zero-padded to a consistent width.
Type or paste text to encode, or paste code to decode. Spaces, commas, and line breaks all work as separators, and continuous binary or hex is auto-split into bytes.
The converted output appears live below. Copy it with one click, or load the sample to see a working example first.
