Decimal ↔ Binary Converter Privacy: All processing runs locally
Convert integers between decimal (base 10) and binary (base 2) number systems.
How It Works
This tool converts integers between the decimal (base 10) number system used in everyday life and the binary (base 2) number system used by computers. Binary represents all values using only two digits: 0 and 1.
Examples:
- Decimal 0 = Binary 0
- Decimal 1 = Binary 1
- Decimal 10 = Binary 1010
- Decimal 42 = Binary 101010
- Decimal 255 = Binary 11111111
- Decimal 1024 = Binary 10000000000
Negative numbers are supported and will include a minus sign prefix. The conversion uses JavaScript's built-in parseInt and toString methods for accuracy. All processing happens in your browser with no data sent to any server.
