Binary Translator

Convert text to binary and binary back to text instantly. Full UTF-8 support, 100% in your browser.

This binary translator converts English text into binary code and decodes binary back into readable text. Type in the input box and the conversion happens live — no button, no upload, no waiting. Every character is encoded as UTF-8 bytes and rendered as space-separated 8-bit groups, which is the format almost every binary translator and textbook uses.

Binary is base-2: each digit is either 0 or 1, and eight of them make one byte. The letter A has the ASCII value 65, which in binary is 01000001. Lowercase a is 97, or 01100001 — the single bit difference is why toggling case in ASCII is such a cheap operation. Emoji and accented characters take more than one byte, and this binary translator handles them correctly by encoding the full UTF-8 sequence.

When decoding, you can paste binary with spaces between bytes or as one continuous stream — the translator detects both. Anything that isn't a 0 or 1 is stripped automatically, so pasting from a chat message or a screenshot transcript usually just works. Nothing you type is transmitted anywhere; the entire conversion runs locally in JavaScript.
