Binary ↔ Text
Convert text to binary code and binary back to text.
🔒 100% private — your files are processed locally and never leave your device.
Underneath every character on your screen is a string of ones and zeros. The Binary ↔ Text tool makes that hidden layer visible, converting any text into its binary representation and decoding binary back into readable text — perfect for learning, puzzles and understanding how computers store letters.
How to use the Binary ↔ Text tool
- Paste text to convert it to binary, or paste binary to decode it.
- Click Text → Binary or Binary → Text.
- Copy the result.
How text becomes binary
Each character is stored as a number according to a standard like ASCII or UTF-8, and that number is written in base-2 as a group of bits — usually eight per character, called a byte. The letter “A”, for example, is 65, which in binary is 01000001. This tool simply automates that lookup in both directions. It is a great way for students to see character encoding in action, and a fun way to hide a short message in plain “computer speak”.
Tips for clean conversion
- Separate bytes with spaces when decoding so the tool can split them correctly.
- Each byte is eight bits for standard ASCII characters.
- Unicode characters may use more than one byte.
- Use it to teach how computers represent letters and numbers.
The conversion happens entirely in your browser, so your text never leaves your device.
