# BinaryTranslator.app

> Free online binary translator that converts binary code to text and text to binary as you type, entirely in the browser. It supports UTF-8 (any language and emoji) and strict ASCII, reads and writes binary, octal, decimal and hexadecimal, and decodes Base64. Nothing the user types is uploaded.

Key facts:

- Binary text is usually written as 8-bit bytes; each byte (0–255) is one character in ASCII, or part of one in UTF-8.
- Example: "Hi" is 01001000 01101001 (72 and 105 in decimal).
- ASCII covers 128 characters (codes 0–127). UTF-8 matches ASCII for those and uses 2–4 bytes for other characters: e.g. é is 2 bytes, 中 is 3 bytes, most emoji are 4 bytes.
- The translator auto-detects whether input is binary or text, accepts spaces, commas, line breaks or no separators, and 7-bit groups, and reports exactly which group is invalid.
- Conversion is private: it runs locally in the browser and share links keep the text after "#" in the URL, which is never sent to the server.
