Binary Multiply
Multiply two binary values locally in your browser.
Tool workspace
Binary multiplication runs locally (unsigned). Max 256-bit product. Nothing you paste is uploaded.
How it works
Enter two binary values (digits 0 and 1). Whitespace is ignored.
The tool multiplies the unsigned values using binary arithmetic (schoolbook bit shifts and adds). The product is shown as binary plus an unsigned decimal companion line. Products longer than 256 bits are rejected.
Everything runs in your browser. Nothing you paste is uploaded.
