Text to Binary Converter

This tool converts ASCII text into binary byte values (8-bit groups). It is useful for learning how text is represented in binary, creating binary-encoded data, or preparing data for systems that work with binary input.

The conversion runs locally in your browser. You can choose a delimiter (space or none) for the output format.

How to use

  1. Enter ASCII text in the input editor.
  2. Choose a delimiter from the dropdown (space or none).
  3. Click Convert to encode the text as binary values.
  4. Use Copy for the clipboard, Download for a text file, or Clear to reset.

How it works

Each character in the ASCII table has a unique number from 0 to 127. The tool looks up the number for each character in your input, converts that number to an 8-bit binary representation, and displays the result. For example, the letter A is 65 in decimal, which is 01000001 in binary.

Example

--- Text Input ---
Hello

--- Binary Output (space delimiter) ---
01001000 01100101 01101100 01101100 01101111

--- Binary Output (no delimiter) ---
0100100001100101011011000110110001101111
