Convert between text and binary code instantly.
Binary is the fundamental language of computers. All data - text, images, videos, programs - is ultimately stored and processed as sequences of 1s and 0s. Understanding binary helps in learning how computers work at the lowest level.
Binary code uses only two digits: 0 and 1. Computers use binary because they operate with electrical signals that are either on (1) or off (0). Each binary digit is called a bit.
Each character is first converted to its ASCII/Unicode number, then that number is converted to binary. For example, "A" is ASCII 65, which is 01000001 in binary.
8 bits (one byte) can represent 256 different values (0-255), which is enough for ASCII characters. UTF-8 uses 1-4 bytes for international characters.
