Binary Code Translator

Translate text to binary (010101) and binary to text. Fun utility for geeks and students.

How This Tool Works
100% Client-Side

Your data never leaves your device. All processing happens locally in your browser. No text is sent to any server, no data is stored, and no cookies track your usage.

Each character is converted to its ASCII code number, then that number is converted to an 8-bit binary representation. Decoding reverses the process by parsing binary strings as base-2 numbers.

  • Uses JavaScript's charCodeAt() and toString(2) for encoding
  • Uses parseInt(binary, 2) and fromCharCode() for decoding
  • Bi-directional conversion updates as you type
How to verify this yourself

Check your browser's Network tab to see nothing is sent:

  1. Open DevTools: Right-click anywhere on the page → "Inspect" (or press F12)
  2. Go to Network tab: Click "Network" at the top of the DevTools panel
  3. Use the tool: Type or paste text and watch the Network tab
  4. Verify: You'll see no requests to external servers — all processing is local

Works in Chrome, Firefox, Safari, and Edge.

How Binary Works

Computers store data using 0s and 1s. Each character is represented by a sequence of 8 bits (a byte). This tool converts ASCII characters to their 8-bit binary representation.
