Frequently Asked Questions
Enter your binary code in the input field (e.g., 01001000 01100101 01101100 01101100 01101111). Each group of 8 digits (bits) represents one character. Click Convert or the result updates automatically. The example converts to "Hello".
Switch to "Text → Binary" mode, type your text, and the binary representation appears instantly. Each character becomes 8 binary digits (bits). For example, "A" becomes "01000001".
Binary is a base-2 number system using only 0s and 1s. Computers use binary because electronic circuits have two states: on (1) and off (0). Text is stored as binary using encoding standards like ASCII or UTF-8.
7-bit ASCII uses 7 digits per character (128 possible characters). 8-bit extended ASCII uses 8 digits (256 characters). Modern systems typically use 8-bit or UTF-8 encoding which can use multiple bytes for special characters.
Each letter has a numeric code in ASCII. For example: A=65, B=66, a=97, b=98. These numbers are converted to binary. So 'A' (65 in decimal) becomes 01000001 in binary.
Hexadecimal (hex) is base-16, using digits 0-9 and letters A-F. It's a compact way to represent binary: each hex digit equals 4 binary digits. For example, binary 1111 = hex F, and 01001000 = hex 48.
Spaces separate each byte (8 bits) for readability. Without spaces, "01001000 01101001" would be "0100100001101001" - much harder to read! Our converter handles both formats.
