Binary Translator

Translate text to binary and binary code back to readable text using UTF-8 bytes. Convert both directions, choose byte separators, and copy the result without sending data to a server.

Binary Text Encoding

This translator uses UTF-8 bytes. Basic ASCII letters use one byte each, while characters outside the ASCII range may use multiple bytes. Each byte is displayed as an 8-bit binary group so it can be decoded reliably.

Code Examples

const bytes = new TextEncoder().encode("Hi");
const binary = [...bytes]
  .map((byte) => byte.toString(2).padStart(8, "0"))
  .join(" "); // "01001000 01101001"

Frequently Asked Questions

What does a binary translator do?

A binary translator converts text into 8-bit binary bytes and converts binary byte groups back into readable text. This page uses UTF-8, so it works for standard ASCII plus many non-English characters.

Why are binary groups 8 bits long?

Text is commonly stored as bytes, and one byte is 8 bits. For ASCII characters, each character maps to one byte. UTF-8 can use more than one byte for characters outside the basic ASCII range.

Can I paste binary without spaces?

Yes. If the input is one long binary string with a length divisible by 8, the translator chunks it into bytes automatically.
