How to Combine PDF Files on Windows

If you are using a Windows PC or laptop, you can utilize one of the best PDF editors trusted by the PCWorld software review site -SwifDoo PDF to combine PDF documents into one. It's lightweight, fast and straightforward to learn and offers 7-day free services. Plus, an open-source PDF merger is introduced as another solution.

SwifDoo PDF

Windows doesn’t have programs for managing PDF documents. To combine PDFs, you need to turn to an external application. SwifDoo PDF software available on Windows 10, 11, 7, and 8 is designed to help you work with PDFs easier and provides two ways for you to combine PDFs. You can either insert a PDF into another or combine multiple PDFs together at once. Moreover, it is not only a PDF combiner but also a PDF splitter, PDF compressor, editor, and more.

Here is a quick look at how to combine PDFs on Windows with two methods.

Method 1: How to Combine Two PDF Files

Step 1: Open a PDF file with SwifDoo PDF;

Step 2: Go to Page on the top and choose Insert in the sub-menu;

Tips: To merge just a few pages of a PDF with another file, specify your needed page numbers and ranges within the “Insert Page” dialogue box, or you can delete the unwanted pages in the combined PDF using a PDF page remover.

After combination, you can open the exported PDF, tap “Page” and drag to re-order the pages. This method shows how to combine two separate PDF files into one by inserting a PDF into another. You can also put three or more PDFs together by inserting more files but it is inefficient. Speaking of how to combine PDFs in batches faster, there is a different method. Let’s read on to learn.

Method 2: How to Combine Multiple PDF Files into One PDF

Step 1: Launch the PDF software and choose Merge PDF in the home interface;

Step 3: Select a location to save the output file and hit Start to combine all PDF files into one.  

Tips: Once you have added PDF files to the PDF merger, you can drag to rearrange them in the order you wish them to appear.

If the combined PDF is too large, you may wonder how to compress it to a smaller size. Compressing a PDF is simpler than you might think. You just need to choose “PDF Compression” in the “SwifDoo PDF Converter” dialogue box to add the PDF, choose the image quality you want, and then tap “Start”.

The Windows-based SwifDoo PDF software not only lets you combine PDFs but also allows you to combine image files into one PDF. What’s more, when you have to split a PDF into several files, SwifDoo PDF can also help.
