Text to Binary Converter
Convert text to binary, hex or octal and back — UTF-8 safe, live, and nothing leaves your browser.
How to use
- Type or paste your text (to encode) or your binary, hex or octal (to decode) into the input box.
- Pick a mode — Text → Binary, Hex or Octal, or one of the reverse directions. It converts as you type.
- Copy the result to your clipboard, or download it as a text file.
FAQ
Is my text sent anywhere?
No. Every conversion runs entirely in your browser using the built-in text encoder, so your input is never uploaded to a server. It works offline and stays completely private.
How is each character turned into binary?
Your text is first turned into UTF-8 bytes. Each byte becomes 8 binary digits (for binary), two characters (for hex) or three characters (for octal). This means emoji and non-Latin scripts convert correctly, since they simply use more than one byte.
What can I paste in to decode?
For decoding, paste the bytes separated by spaces, newlines or tabs — binary as groups of 8 bits, hex as pairs, octal as triples. Extra whitespace is ignored. If the input isn’t valid for the chosen base, you’ll get a gentle nudge instead of a wrong answer.
