Understanding Binary Code

Binary code is the fundamental language of computers, using only two digits: 0 and 1. Each character in text is represented by a unique sequence of 8 bits (binary digits), called a byte. For example, the letter 'A' is represented as 01000001 in binary.

ASCII encoding assigns each character a number from 0 to 127, which is then converted to binary. For instance, uppercase 'A' is ASCII 65, which is 01000001 in binary, while lowercase 'a' is ASCII 97 (01100001).

This tool uses standard 8-bit ASCII encoding, where each character is represented by exactly 8 binary digits, making it easy to read and understand the binary representation of text.

Common Use Cases

  • Education: Learn how computers represent text in binary form
  • Programming: Debug binary data or understand character encoding
  • Data Transmission: Encode text for binary protocols or communication
  • Cryptography: Study basic encoding and data representation
  • Computer Science: Understand ASCII and binary number systems
  • Testing: Verify binary data encoding and decoding accuracy

Binary Format Options

Space Separated: The most readable format with spaces between each byte (e.g., "01001000 01100101 01101100 01101100 01101111" for "Hello"). This format is easy to read and understand.

Continuous: All binary digits in one continuous string without spaces (e.g., "0100100001100101011011000110110001101111"). This format is compact and used in data transmission.

Each Byte on New Line: Each character's binary representation on a separate line for easy analysis and comparison.

Tips for Using This Converter

  • Use space-separated format for better readability when learning or teaching
  • The binary-to-text mode automatically detects spaces and removes them
  • Use the Swap button to quickly test round-trip conversions (text → binary → text)
  • Each 8-bit sequence represents exactly one ASCII character
  • Copy and paste binary code from various sources - the tool handles formatting

Examples

Example 1: The text "Hi" converts to:
Space-separated: 01001000 01101001
Continuous: 0100100001101001

Example 2: The binary 01001000 01100101 01101100 01101100 01101111 converts to:
Text: Hello

Example 3: Numbers work too! "123" converts to:
Binary: 00110001 00110010 00110011
