What it does
PDF Merger combines several PDFs into a single file directly in the visitor's browser. No account, no watermarks, and no data is uploaded or stored on a server. The tool works on both desktop and mobile browsers, providing a straightforward drag‑and‑drop interface and instant download of the merged result.
