Since you prefer a completely free method without installing third-party software, the OneDrive Online method is an excellent choice. Microsoft offers this as a built-in PDF merger tool for anyone with a free Microsoft account. Here is exactly how to combine your ebook parts:

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.

Note: This online PDF merger tool processes files in Microsoft's secure cloud, not on your local PC. However, Microsoft states that your documents are protected and not shared with third parties.
