What is Binary Converter (Text to Binary)?
Binary is a base-2 number system using only 0s and 1s. Computers store all data as binary because electronic circuits have two states: on (1) and off (0). Each character in text is represented by a sequence of 8 binary digits (bits) called a byte. For example, the letter 'A' is 01000001 in binary (65 in decimal).

Frequently Asked Questions
What format should binary input be in?
Binary digits can be separated by spaces (01001000 01100101) or written as a continuous string (0100100001100101). The tool automatically strips non-binary characters and groups them into 8-bit bytes.
Why does each character become 8 binary digits?
Standard ASCII uses 7 bits per character, but computers store data in 8-bit bytes. The leading bit is padded with 0. So 'A' (decimal 65) becomes 01000001, not just 1000001.
Does this support Unicode characters?
This tool converts each character using its UTF-16 code unit (JavaScript's charCodeAt). For standard ASCII characters (0-127), the result is the same as ASCII binary. Non-ASCII characters may produce values above 255.
