Step-by-step instructions:
1. Upload your PDF files to your OneDrive personal storage (you get 5 GB free with any Microsoft account).
2. Open OneDrive in your web browser (onedrive, live, com) and navigate to the folder containing your PDFs.
3. Click on one of the PDF files to open it in the Microsoft Office web viewer.
4. Look for the Merge icon in the top toolbar—it typically looks like two pages stacked together or appears under the three-dot (···) menu labeled "Merge" .
5. Select the other PDF files you want to combine from the list that appears.
6. Click "Merge" or "Save" to download your new, single PDF file.
