What is Binary To Decimal Converter?
Binary To Decimal is a free online number base converter. It lets you instantly convert any number between binary (base-2), decimal (base-10), hexadecimal (base-16), and octal (base-8) systems. Just type a number, select its base, and all conversions appear simultaneously.
How It Works
The tool uses JavaScript's built-in parseInt(value, fromBase) to parse the input in its source base, then calls .toString(toBase) to render the result in each target base. All computation runs entirely in your browser — nothing is sent to any server.
Key Benefits
- Converts all four common number bases at once
- Instant live conversion as you type
- Validates input and shows clear error messages
- Supports large numbers up to JavaScript's safe integer limit
- Zero dependencies — runs 100% in your browser
