Binary code is the fundamental language of computers. Every piece of data — text, images, videos, programs — is ultimately stored and processed as a sequence of 0s and 1s. This is because computer processors are made of billions of tiny switches that can be either ON (1) or OFF (0).
Each character in text is represented by a unique 8-bit binary number (called a byte). For example, the letter "A" in binary is 01000001, which equals 65 in decimal. This mapping is defined by the ASCII and Unicode standards.
Our binary converter supports four conversion modes: text to binary (for encoding messages), binary to text (for decoding), decimal to binary (for number system conversion), and binary to decimal (for reading binary numbers).

Frequently Asked Questions
How do I convert text to binary?▼
Type or paste your text in the input box, select the Text to Binary mode, and click Convert. Each character is converted to its 8-bit binary representation separated by spaces.
How do I read binary code?▼
Each group of 8 digits (a byte) represents one character. Convert each byte from base-2 to base-10 to get the ASCII code, then look up the corresponding character.
Is binary the same as Base-2?▼
Yes. Binary is the base-2 number system, using only digits 0 and 1. Decimal is base-10 (0-9). Hexadecimal is base-16 (0-9 and A-F).
Is this tool free?▼
Yes, completely free. No account or sign-up needed.
