Binary addition

Client

Add two binary numbers without converting to decimal first—paste bit strings.

About Binary addition

Add two binary strings and return sum as binary. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.

How to use this page

Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.
