Combine multiple PDF files into a single document. Drag to reorder, then merge — 100% in your browser.
PDF Merger is a free online tool that lets you combine two or more PDF documents into a single file. Unlike other tools that upload your files to a server, our merger processes everything directly in your browser using JavaScript — your files never leave your device. Simply drag and drop your PDFs, reorder them as needed, and download the merged result instantly. No signup, no file size limits, no watermarks.
