Convert any text to binary code instantly. Choose delimiter, encoding (8-bit or UTF-16), and optionally display decimal or hex alongside each byte.
Multiple formats, encodings, and display options
Standard 8-bit ASCII for English text, or 16-bit UTF-16 for full Unicode character support.
Space, comma, newline, or no delimiter โ combine with decimal or hex display for learning.
Copy the full binary output to clipboard or download it as a plain text file instantly.
All conversion happens in your browser. No data is sent to any server.

Text-to-binary conversion encodes human-readable text into binary code (0s and 1s) using ASCII or UTF-8 encoding. Each character maps to an 8-bit binary number โ the fundamental way computers store and process text internally.
Understand how computers actually store text at the hardware level โ every letter, space, and punctuation mark is stored as a sequence of binary digits.
Convert messages to binary for use in educational puzzles, coding challenges, CTF (Capture the Flag) competitions, or just for fun with friends.
Inspect binary representations when working on low-level programming, network protocols, file format parsing, or embedded systems development.
Teachers use binary converters in CS lessons to demonstrate character encoding, binary arithmetic, and how digital information is represented in computers.
ASCII (American Standard Code for Information Interchange) assigns numbers 0โ127 to basic characters. For example, 'A' = 65 = 01000001 in binary. UTF-8 extends this to support international characters using 1โ4 bytes per character. This fundamental encoding is the bridge between human language and machine computation.
