Free Binary to Text Converter – Decode Binary to Readable Text Online

Convert binary code to readable text instantly. See byte-by-byte breakdown with ASCII values. Decode secret binary messages. Works with any binary input. 100% free.

What Is Binary to Text Conversion?

Binary to text conversion decodes binary numbers (sequences of 0s and 1s) into human-readable characters. Each 8-bit binary sequence represents one ASCII character.

How Computers Store Text

Computers store all data as binary. When you type "Hello":

• H → 01001000
• e → 01100101
• l → 01101100
• l → 01101100
• o → 01101111

This tool reverses the process to reveal the original text.

How to Convert Binary to Text

The Simple Method

1. Group into bytes: Divide binary into 8-bit groups
2. Convert each byte: Get the decimal value (0-255)
3. Look up character: Find the ASCII character for that value

Example: Decode "Hi"

Binary input: 01001000 01101001

Result: "Hi"

Common Binary Messages

Here are some frequently encoded phrases:

Use Cases

Decode Secret Messages

Binary is sometimes used to encode messages in games, puzzles, and ARGs (alternate reality games).

Computer Science Education

Understanding binary-to-text conversion is fundamental to learning how computers work.

Data Recovery

When dealing with raw binary data, converting to text helps identify content.

Programming & Debugging

Developers sometimes need to decode binary strings in logs or data files.

Understanding ASCII vs UTF-8

ASCII (American Standard Code)

• 7 bits originally, now 8 bits
• 128 characters (0-127)
• English letters, numbers, basic symbols

UTF-8 (Universal Text Format)

• Variable length (1-4 bytes)
• Supports all languages
• Backward compatible with ASCII

This tool decodes standard ASCII/UTF-8 encoded binary.

Programming Examples

JavaScript

const binary = '01001000 01101001';
const text = binary.split(' ')
    .map(byte => String.fromCharCode(parseInt(byte, 2)))
    .join('');
// Result: 'Hi'

Python

binary = '01001000 01101001'
text = ''.join(chr(int(b, 2)) for b in binary.split())
# Result: 'Hi'

Frequently Asked Questions

What if my binary doesn't divide into 8 bits?

The tool pads the leftmost group with zeros. For accurate decoding, ensure your input is complete 8-bit bytes.

What about non-ASCII characters?

Characters outside the 0-127 range will decode but may not display correctly. Extended ASCII (128-255) varies by encoding.

Can I decode any binary?

Yes, but not all binary represents text. Image files, executables, etc. won't produce meaningful text.

What do the dots (·) mean?

Non-printable characters (like control characters) are displayed as dots for visibility.

Does spacing matter?

No. Spaces are optional. The tool processes all binary digits regardless of formatting.

Tips for Accurate Decoding

1. Complete bytes: Ensure you have full 8-bit sequences
2. Remove extra characters: Only 0s, 1s, and spaces should be input
3. Check encoding: Most text is ASCII; special characters may need different handling
4. Verify source: Make sure the binary actually represents text
