Combine two or more PDF files into a single document, in the order you choose.
1. Click the box above and select two or more PDF files (or drag and drop them in).
2. Reorder them if needed — files merge top to bottom in the list.
3. Click "Merge PDFs" and download your combined file.
Because everything runs locally in your browser using WebAssembly, there's no file size limit imposed by a server, no waiting on an upload, and no copy of your document is ever transmitted anywhere.
