Text ↔ Binary Converter

What is Binary?

Binary is the fundamental language of computers, using only two digits: 0 and 1. Each binary digit (bit) represents an on or off state in computer circuits. Eight bits grouped together form a byte, which can represent 256 different values (0-255). Computers store and process all data—text, images, video—as sequences of binary numbers.

Example: The letter 'A' in binary is 01000001 (decimal 65)

ASCII Encoding

ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numbers to letters, digits, and symbols. It uses 7 bits, allowing for 128 different characters (0-127). Extended ASCII uses 8 bits for 256 characters. ASCII is the foundation of text representation in computers and includes uppercase and lowercase letters, digits, punctuation, and control characters.

ASCII ranges: A-Z: 65-90, a-z: 97-122, 0-9: 48-57

Example: 'Hello' = 01001000 01100101 01101100 01101100 01101111

UTF-8 Encoding

UTF-8 (8-bit Unicode Transformation Format) is a variable-length character encoding that can represent every character in the Unicode standard. It uses 1 to 4 bytes per character. UTF-8 is backward compatible with ASCII—the first 128 characters are identical. It's the most widely used character encoding on the web, supporting all languages, emojis, and special symbols.

Usage: Supports all world languages, emojis, mathematical symbols

Example: 'café' requires multi-byte encoding for the 'é' character

How Text-to-Binary Works

When converting text to binary, each character is first converted to its numeric code (ASCII or Unicode code point), then that number is converted to binary. For example, 'A' has ASCII code 65, which is 01000001 in 8-bit binary. The reverse process (binary to text) converts each 8-bit group back to its decimal value, then to the corresponding character.

Process: Text → Character codes → Binary numbers → Binary string

Reverse: Binary string → Binary numbers → Character codes → Text

Common Use Cases

Text-to-binary conversion has various practical applications: understanding how computers store text data, debugging communication protocols, learning programming concepts, creating puzzles or encoded messages, analyzing data transmission, and educational purposes for computer science students.
