Add Binary Numbers
Sum binary numbers
Add multiple binary values together and view the result in binary, decimal, hex, and octal.
How it works
Enter binary numbers separated by spaces, commas, or newlines. The tool will sum all values and display the result in multiple number formats (binary, decimal, hexadecimal, octal).
One number per line, or separate with spaces/commas0 numbers
Binary addition follows the same rules as decimal addition, but carries occur at 2 instead of 10. This tool handles arbitrarily large binary numbers and provides results in multiple number systems. All processing happens locally in your browser.
