How Binary Code Works

Binary is a base-2 number system that uses only two digits: 0 and 1. Computers use binary because electronic circuits can easily represent two states: on (1) and off (0).

Text Encoding (ASCII)

Each character is assigned a number in the ASCII standard. For example, 'A' is 65, 'a' is 97. These numbers are then converted to 8-bit binary (a byte). The letter 'A' (65) becomes 01000001.

Example: "Hi" in Binary

H → ASCII 72 → 01001000

i → ASCII 105 → 01101001

Result: 01001000 01101001

Binary Place Values

Each position in binary represents a power of 2, from right to left: 1, 2, 4, 8, 16, 32, 64, 128. To convert binary to decimal, add the values where there's a 1.

Frequently Asked Questions

How does binary represent text?

Each character is assigned a number using ASCII (or Unicode). For example, 'A' is 65. This number is then converted to binary (base-2). The number 65 in binary is 01000001. Each character uses 8 bits (1 byte).

Why are there 8 digits in each binary group?

Each group of 8 binary digits is called a byte. A byte can represent 256 different values (2^8 = 256), which is enough to encode all basic ASCII characters including letters, numbers, and symbols.

What if my binary doesn't decode correctly?

Make sure your binary is in complete 8-bit groups. Incomplete groups will be ignored. Also check that you only have 0s and 1s - any other characters (except spaces as separators) will be removed.

Can I convert emojis to binary?

This tool uses ASCII encoding which doesn't support emojis. Emojis require Unicode (UTF-8/UTF-16) encoding which uses more than 8 bits per character. The result may not convert correctly.

What's the difference between binary and hexadecimal?

Binary uses base-2 (0-1), while hexadecimal uses base-16 (0-9 and A-F). Hex is more compact - one hex digit represents 4 binary digits. "01001000" in binary is "48" in hex.

Is this how computers actually store text?

Yes! At the hardware level, all computer data is stored as binary (electrical on/off states). Text, images, videos - everything is ultimately 1s and 0s. This tool shows the ASCII binary representation.
