Binary/Text Converter
Convert plain text to binary code, or binary code back to text.
About this tool
Convert plain text into binary code (8-bit chunks, one per character), or binary code back into readable text — direction is detected automatically.
Key Features
- Automatic direction detection
- One 8-bit byte per character
- Handles standard ASCII text
- Instant results
How to Use
- Type text, or paste binary code as space-separated 8-bit bytes.
- Click Convert.
- Read the result in the other format.
Benefits
- Understand how computers represent text as numbers
- Decode a binary message
- Check homework or a computer science assignment
Frequently Asked Questions
A single bit can only represent 2 values (0 or 1), but 8 bits together can represent 256 different values (2 to the power of 8), which is enough to cover the standard ASCII character set — all uppercase and lowercase letters, digits, and common punctuation and control characters.
This tool works with standard ASCII characters (English letters, digits, and common punctuation). Characters outside that range, such as emoji or many non-Latin scripts, use more complex multi-byte encodings and are not what this simple one-byte-per-character tool is designed for.
Every character has a numeric code point (for example, the capital letter "A" is 65 in ASCII). That number is converted to base 2 and padded to 8 digits, giving 01000001 for "A". Decoding simply reverses the process: each 8-digit binary group is converted back to its decimal code point, then to the matching character.
