Binary Converter
Convert between text and binary representation instantly.
What is Binary Converter?
A binary converter translates text characters into their binary (base-2) representation and vice versa. Each character is represented as an 8-bit binary number (byte). Binary is the fundamental language of computers, and understanding binary encoding is essential for low-level programming, data transmission, and computer science education.
How to Use This Tool

Frequently Asked Questions
Why are binary numbers grouped in 8 bits?
8 bits (1 byte) is the standard unit for representing characters in ASCII and UTF-8 encoding. Each 8-bit group can represent 256 different values, enough for all ASCII characters.
What character encoding does this use?
This converter uses UTF-8 encoding, which is compatible with ASCII for basic characters. Each standard ASCII character uses 8 bits, while extended Unicode characters may use more.
How do I convert binary back to text?
Switch to 'Binary → Text' mode and enter space-separated 8-bit binary numbers. For example, '01001000 01101001' converts to 'Hi'.
