Convert numbers across various base systems instantly. Simply enter a value in any field and watch the others update in real-time.
A binary converter (or number base converter) is a tool that translates values between different counting systems. While we typically use Decimal (Base 10) in daily life, computers operate on Binary (Base 2). Developers also frequently use Hexadecimal (Base 16) and Octal (Base 8) to represent binary data in a more human-readable format.
You can start typing in any of the four input fields. The tool detects which base you are using and converts that value to all other supported bases.
If you type a character that isn't valid for a specific base (like '2' in binary or 'G' in hex), the tool will highlight the error and pause conversion.
Use the copy icon next to each result to instantly bring that specific format into your code, documentation, or assignment.
