What is this tool?
The Text to Binary Converter translates ASCII and Unicode text into 8-bit binary code, decimal values, hexadecimal pairs, or octal representations, and decodes binary sequences back into human-readable text. It processes every character code point in real time and provides one-click copying and mode swapping.
How to convert text to binary and vice versa
- Select your output encoding format: Binary, Decimal, Hexadecimal, or Octal.
- Ensure the direction toggle is set to Encode (Text to Binary) or Decode (Binary to Text).
- Enter or paste your text or binary sequence into the input field.
- Copy the resulting converted output using the copy button.
Key Features
- Converts text to 8-bit binary bytes, decimal numbers, hexadecimal, and octal
- Bidirectional conversion: encode text to binary or decode binary back to plain text
- Full UTF-8 / Unicode character code support via charCodeAt and String.fromCharCode
- Instant real-time conversion with copy and swap controls
Frequently Asked Questions
How does text-to-binary conversion work?
Each character in your text has an underlying numeric character code (ASCII or Unicode). The converter takes that integer and expresses it in base-2 notation as an 8-bit byte.
How do I decode binary numbers back into readable text?
Set the tool direction to Decode, select Binary mode, and paste your space-separated 8-bit bytes. The converter reads each byte, finds the corresponding character, and reconstructs your text.
Why are binary bytes separated by spaces?
Standard binary text formatting uses spaces between 8-bit chunks so you can distinguish where one character ends and the next begins.
Can I convert text to Hexadecimal, Decimal, or Octal?
Yes. You can switch between Binary (base-2), Decimal (base-10), Hexadecimal (base-16), and Octal (base-8) with one click.
