Binary

Binary is a base-2 number system using only 0 and 1. Each text character is represented by its ASCII code converted to 8 binary digits (bits). For example, "A" is 65 in decimal, which is 01000001 in binary.

Binary uses base 2 (digits 0-1), octal uses base 8 (digits 0-7), and hexadecimal uses base 16 (digits 0-9 and A-F). They are all different ways to represent the same numbers.

Standard ASCII uses 7 bits (0-127) to represent characters, but it is conventionally stored in 8 bits (a byte) for alignment. Extended ASCII and UTF-8 use 8 or more bits per character.

Yes, switch to Binary to Text mode and paste space-separated 8-bit binary values. The tool will decode each byte back to its corresponding text character.

The tool converts characters based on their Unicode code points. Basic ASCII characters (0-127) work with 8-bit representation. Characters above 127 may require multiple bytes.
