About Binary Encoding
Binary is the fundamental language of computers · every character, number, and instruction is ultimately represented as a sequence of 0s and 1s. In the ASCII encoding standard, each character maps to a 7-bit binary value (commonly shown as 8 bits with a leading zero). For example, the letter "A" is 01000001 (decimal 65).
This tool converts between human-readable text and its binary representation. It supports the full ASCII range (0-127) for binary-to-text, and converts each character to its 8-bit binary equivalent for text-to-binary.

Frequently Asked Questions
What format should the binary input be in?
Enter 8-bit binary values separated by spaces (e.g., "01001000 01101001"). The tool also accepts values without spaces if each byte is exactly 8 digits, or comma-separated.
Does this support emoji or non-English characters?
The text-to-binary direction supports any Unicode character · each character is expanded into its full binary representation using UTF-8 encoding. For binary-to-text, each 8-bit group is decoded as an ASCII byte (0-255).
Why are there 8 digits per character?
Each group of 8 binary digits (bits) represents one byte. ASCII uses 7 bits (values 0-127) but is commonly shown as 8 bits with a leading zero. One byte can represent 256 different values (0-255), which covers all standard keyboard characters.
