The Binary Converter translates text to binary code (sequences of 0s and 1s) and binary code back to readable text. Each character is converted to its 8-bit binary representation based on the ASCII/UTF-8 standard, with individual bytes separated by spaces for readability.
Binary is the foundational number system of computing. All data stored and processed by computers — including text, images, and code — ultimately exists as binary values. Understanding binary and being able to convert between text and binary is essential for anyone studying computer science, networking, digital electronics, or cybersecurity.
For text, each character is mapped to its ASCII decimal code, which is then expressed as an 8-bit binary number. The letter 'A' is ASCII 65, which in binary is 01000001. The lowercase 'a' is ASCII 97, which in binary is 01100001 — they differ by a single bit (the 6th bit controls case in the ASCII table).
The converter handles any standard ASCII character including letters, digits, spaces, and common punctuation. For extended Unicode characters, the underlying UTF-8 byte sequence is used, which may produce multiple 8-bit groups per character.
All conversion runs locally in your browser. Nothing is uploaded or stored.
Enter text or binary code into the input.
Select Text → Binary or Binary → Text.
Copy the result.
UTF-8 encoding — each ASCII character becomes 8 binary digits. Extended characters may produce multiple bytes.
A single space separates the 8-bit binary value for each character, making it easy to identify individual characters.
8 bits (1 byte) per ASCII character. For example, 'A' is 01000001 and 'a' is 01100001.
Yes — paste space-separated 8-bit binary groups and select Binary → Text mode.
A space character is 00100000 in 8-bit binary (ASCII 32).
