What is Base2 (Binary)?

Base2, commonly known as binary, is the most fundamental encoding system in computing. It uses only two digits (0 and 1) to represent all data. Each digit is called a bit, and 8 bits form a byte. Binary is the native language of computers and digital systems.

How It Works

Encoding: Each character in the input text is converted to its UTF-8 byte representation. Each byte is then converted to an 8-bit binary number, with leading zeros added if necessary. The binary digits are grouped by 8 bits with spaces for readability.

Decoding: The binary string is processed in groups of 8 bits (bytes). Each byte is converted back to its decimal value, and these values are used to reconstruct the original UTF-8 text.

• Uses only two characters: 0 and 1.
• Each character is represented by 8 bits (1 byte).
• Most fundamental encoding system in computing.
• Direct representation of computer memory.
• Whitespace between bytes is optional for readability.

Use Cases

Binary encoding is fundamental to computing:

• Computer Memory: Direct representation of data in computer memory.
• Digital Electronics: Used in circuit design and digital logic.
• Data Storage: Foundation of all digital storage systems.
• Network Protocols: Used in low-level network communication.

Why Use Binary?

Binary is the foundation of all digital computing:

• Fundamental: The most basic form of data representation.
• Universal: Used by all digital systems.
• Precise: Direct representation of digital data.

While binary is not space-efficient for human-readable text, it's essential for understanding how computers process and store data.

How to Use This Tool

1. Select either "Encode" or "Decode" mode.
2. Enter the text (UTF-8 for encoding) or binary string (for decoding) into the top input field.
3. The result will appear automatically in the bottom output field.
4. Use the swap button to switch the input and output, automatically changing the mode.
5. Click the copy icon next to the output label to copy the result.
6. Error messages will appear for invalid binary input or if the decoded data is not valid UTF-8.
