Text to Binary Converter

Convert text to binary representation and binary back to text. Supports ASCII and UTF-8 encoding with space-separated bytes.

Loading...
1. Type or paste plain text into the Text input field to convert it to binary. 2. View the space-separated 8-bit binary output that appears instantly for each character. 3. To convert binary to text, enter space-separated binary values (e.g., 01001000 01101001) into the Binary input field. 4. Select the encoding mode (ASCII or UTF-8) if you need to handle multi-byte characters like emoji. 5. Click the copy button to copy the binary output or decoded text to your clipboard.

About This Tool

The Text to Binary Converter transforms any text into its binary representation and converts binary strings back into readable text. Each character is encoded as an 8-bit binary byte (or multiple bytes for UTF-8 characters), making it easy to see the underlying digital representation of your text.

This tool supports full UTF-8 encoding, so it handles not just basic ASCII characters but also accented letters, emoji, Chinese characters, and any other Unicode text. The binary output uses space-separated byte groups for readability, and the decoder intelligently parses space-separated binary values back into the original text.

Whether you are learning about binary number systems, studying computer science fundamentals, encoding messages for fun, or debugging character encoding issues, this bidirectional converter gives you instant results. All processing happens in your browser - no data is sent to any server.

Frequently Asked Questions

Each character in your text is converted to its UTF-8 byte representation, and each byte is expressed as an 8-digit binary number (using only 0s and 1s). For example, the letter "A" has the ASCII value 65, which is 01000001 in binary.
Yes. The converter uses UTF-8 encoding, which supports all Unicode characters including emoji, accented letters, Chinese, Japanese, Korean, Arabic, and every other script. Multi-byte characters will produce multiple 8-bit binary groups.
Enter space-separated 8-bit binary values in the Binary field. Each group of 8 binary digits represents one byte. The tool will decode the bytes using UTF-8 and display the resulting text.
ASCII uses a single byte (8 bits) per character and only covers 128 characters. UTF-8 is backward-compatible with ASCII but uses 1 to 4 bytes per character, supporting over 1 million Unicode code points including all world scripts and emoji.
