How to Convert Text to Binary

  1. Enter your text in the left panel
  2. Select encoding (UTF-8, ASCII, or UTF-16)
  3. Choose formatting options (spaces, prefix)
  4. Click "Convert to Binary" to see the result
  5. Copy or download the binary output

Each character becomes an 8-bit binary number (byte).

How to Convert Binary to Text

  1. Enter binary code in the right panel
  2. Select bit format (6-bit, 7-bit, or 8-bit)
  3. Enable auto-remove spaces for messy input
  4. Click "Convert to Text" to decode
  5. Copy or download the decoded text

Spaces between bytes are optional - we handle both.

Frequently Asked Questions

Is this text to binary converter free?
Yes, completely free! No hidden costs, no registration. Convert unlimited text and binary instantly.
Is my data stored?
No. All conversions happen locally in your browser. We do not store, log, or transmit any text or binary you enter. Your privacy is fully protected.
What's the difference between UTF-8 and ASCII?
ASCII uses 7 or 8 bits per character and only supports English letters, numbers, and basic symbols. UTF-8 supports all Unicode characters (emojis, accents, different languages) and uses variable-length encoding.
Why do I see 8-bit binary (bytes)?
Computers store text as bytes (8 bits). Each character is represented by one or more bytes depending on the encoding. UTF-8 uses 1 byte for English, more for other languages.
What does "0b" prefix mean?
In many programming languages, "0b" at the start of a number indicates it's binary. For example, 0b01000001 is the same as 65 in decimal. This option helps when you need programming-compatible output.
Can I use this for learning computer science?
Absolutely! This tool is great for students learning how computers represent text. You can see exactly how "Hello" becomes 01001000 01100101 01101100 01101100 01101111 in binary.

How Binary Converter Works

This tool converts text characters into their binary representations (and vice versa) using standard character encoding. Each character is represented as an 8-bit binary number (byte).

  • Computer Science Education: Understand how computers store and process text data
  • Programming & Development: Debug encoding issues or work with binary data
  • Network Protocols: Analyze binary data in network communications
  • Data Transmission: Prepare text for binary transmission systems
  • Security & Cryptography: Work with binary representations in encryption

Encoding & Features

The converter supports multiple encodings and customization options for different use cases.

  • Multiple Encodings: UTF-8, ASCII, UTF-16 support
  • Formatting Options: Add spaces between bytes, include 0b prefix
  • Bit Length: 6-bit, 7-bit, or 8-bit binary formats
  • Real-time Updates: Settings changes auto-convert your content
  • Error Detection: Validates binary input and handles encoding errors gracefully

All conversions happen locally in your browser - no data is sent to any server.
