Binary to Text — How It Works
Binary code represents text using 8-bit groups called bytes. Each byte corresponds to one character in the ASCII or Unicode table. The converter reads 8 binary digits at a time and looks up the corresponding character. For example: 01001000 = 72 in decimal = the letter H. 01100101 = 101 = lowercase e. 01101100 = 108 = lowercase l. So 01001000 01100101 01101100 01101100 01101111 = "Hello".
Text to Binary — Encoding Text
To encode text to binary, each character is converted to its ASCII (or Unicode) code number, then that number is expressed as 8 binary digits. The letter A = ASCII 65 = 01000001. Lowercase a = 97 = 01100001. Space = 32 = 00100000. Digits 0–9 start at ASCII 48 (00110000) through 57 (00111001).
Binary, Decimal, Hexadecimal — How They Relate
Binary (base 2), decimal (base 10), and hexadecimal (base 16) are all ways to represent the same numbers. The letter A is decimal 65, binary 01000001, and hex 41. Computers work internally in binary; developers often use hex as a compact way to represent binary (each hex digit = 4 binary digits). The ASCII Converter tool on this site also shows hex and octal representations.
