The Binary/Text converter transforms plain text into 8-bit binary representation and decodes binary strings back to readable text. Each character is represented as a sequence of eight 0s and 1s corresponding to its ASCII or Unicode value.

This tool is useful for learning about character encoding, understanding how computers store text, and working with binary data in educational or programming contexts. Choose between space-separated binary bytes or continuous binary strings.

All conversions run in your browser — no data is sent to external servers. This ensures your text remains private while you explore binary representations.

How to Use Binary to Text / Text to Binary Converter

  1. 1Enter text in the input area to see its binary representation.
  2. 2Choose between space-separated or continuous binary format.
  3. 3Switch to Decode mode to convert binary back to text.
  4. 4Copy the result using the Copy button.

Frequently Asked Questions

How does text to binary conversion work?▾
Each character has a numeric code (ASCII or Unicode code point). This number is converted to its binary (base-2) representation, padded to 8 bits. For example, the letter 'A' is 65 in decimal, which is 01000001 in 8-bit binary.
What is 8-bit binary?▾
8-bit binary means each value is represented using exactly 8 digits (bits), padded with leading zeros if needed. This is the standard byte size used in computing and can represent values from 0 (00000000) to 255 (11111111).
Can I convert binary back to text?▾
Yes. Switch to Decode mode and paste your binary string. The tool will convert each 8-bit group back to its corresponding character. Both space-separated and continuous binary strings are supported.
What happens with characters outside the standard ASCII range?▾
Characters beyond the basic ASCII range (code points above 127), such as accented letters or emojis, are encoded using their full Unicode code point value in binary. This may produce binary sequences longer than 8 bits, reflecting the larger numeric values of these characters.
