Frequently Asked Questions
How does text to binary conversion work?
Each character in the text is converted to its ASCII (or Unicode) code point, which is then expressed as an 8-bit binary number. For example, the letter "A" has the ASCII code 65, which in binary is 01000001. The resulting binary groups are separated by spaces so they can be individually identified and reversed back to text.
What is binary code?
Binary code is a system of representing data using only two digits: 0 and 1. Computers use binary because their electronic circuits can be in one of two states — on (1) or off (0). All data inside a computer, including text, images, and programs, is ultimately stored and processed as sequences of these binary digits (bits).
What does 8-bit binary mean?
An 8-bit binary number uses exactly 8 binary digits (bits) to represent a value, giving a range of 0 (00000000) to 255 (11111111). In this converter, each character is encoded as an 8-bit binary group. This aligns with the ASCII standard, which maps 128 characters to values 0–127, fitting easily in 8 bits. Extended ASCII uses values 128–255 for additional characters.
