What is binary and how does it work?

Binary is a base-2 number system using only digits 0 and 1. Computers use binary internally because electronic circuits have two states: on (1) and off (0). Each binary digit is called a "bit," and 8 bits make a "byte" that can represent values 0-255.

How do I convert text to binary online?

Paste your text into the input field, select "Text to Binary" mode, and the binary representation appears instantly. Each character is converted to its 8-bit binary equivalent. You can choose different separators (space, none) between bytes.

How do I convert binary to text?

Paste your binary string into the input field, select "Binary to Text" mode, and view the decoded text instantly. The converter accepts binary with spaces, commas, or no separators between bytes. Each 8-bit group is converted to its character.

Why are there 8 binary digits per character?

Each character is represented by one byte (8 bits) in standard ASCII encoding. 8 bits can represent 256 different values (0-255), covering all ASCII characters. UTF-8 encoding may use 1-4 bytes for extended characters like emoji.

How do I read and understand binary numbers?

Each position represents a power of 2 from right to left: 1, 2, 4, 8, 16, 32, 64, 128. Add the values where there is a 1. Example: 01000001 = 64 + 1 = 65 = "A" in ASCII. The rightmost bit is the "least significant bit" (LSB).

What binary separators and formats are supported?

This tool accepts binary with spaces (01001000 01101001), commas (01001000,01101001), colons, dashes, or no separator (0100100001101001). It automatically detects the format and handles various input styles.

Why am I getting "length must be multiple of 8" error?

Each byte needs exactly 8 bits. If your binary string has a different length, it cannot be converted to complete bytes. Add leading zeros to make each group 8 bits (e.g., "1000001" should be "01000001").

How does Unicode and UTF-8 work with binary?

Unicode characters are encoded as UTF-8, which uses 1-4 bytes per character. ASCII characters (0-127) use 1 byte. Extended characters use multiple bytes: "é" = 2 bytes (11000011 10101001), emoji = 4 bytes.

What is the difference between binary and hexadecimal?

Binary uses 2 symbols (0, 1) while hex uses 16 (0-9, A-F). One hex digit equals exactly 4 binary digits, making hex more compact. Example: binary 11111111 = hex FF = decimal 255. Hex is easier to read for humans.

How do I convert binary to decimal?

Multiply each bit by its position value (powers of 2) and sum them. For 8-bit binary: bit7×128 + bit6×64 + bit5×32 + bit4×16 + bit3×8 + bit2×4 + bit1×2 + bit0×1. Example: 01000001 = 0+64+0+0+0+0+0+1 = 65.

What is ASCII and how does it relate to binary?

ASCII (American Standard Code for Information Interchange) maps numbers 0-127 to characters. Each ASCII character has a unique binary representation: "A" = 65 = 01000001, "a" = 97 = 01100001, "0" = 48 = 00110000.

Can I convert binary to other formats like hex or octal?

Yes! Binary converts easily to hex (group 4 bits) and octal (group 3 bits). This tool shows the text representation, but you can use our Hex converter for hex output. Binary 11111111 = Hex FF = Octal 377 = Decimal 255.

What are common binary values to know?

Useful binary values: 00000000 = 0, 11111111 = 255 (max byte), 01000001 = "A", 01100001 = "a", 00110000 = "0", 00100000 = space, 00001010 = newline. Powers of 2: 1, 2, 4, 8, 16, 32, 64, 128.

How is binary used in computers and programming?

Computers store and process all data as binary. Binary is used for: machine code instructions, memory addresses, file storage, network protocols, bitwise operations, flags and permissions, and low-level hardware communication.

Is my data secure when using this binary converter?

Yes! All conversion happens 100% in your browser using JavaScript. Your text and binary data never leave your device or get sent to any server. This makes it safe for converting sensitive data or learning binary encoding.
