To put or merge together relevant PDFs into one individual document is conducive to file archival. No one wants to be tortured by a messed-up desktop full of unclassified files. In some cases, you may need to bundle together multiple PDFs for easier file transfer. If you do face the above situation, you may need to know how to combine multiple PDFs into one.

We may have been asked to merge PDFs at work. Do you face this situation of combining two PDFs or more into one document? This post will elaborate on several useful PDF mergers on Windows, Mac, and online to help put multiple PDF files together.

How to Combine Multiple PDFs into One on Windows

For Windows users, combining multiple PDFs into one requires a third-party PDF tool to accomplish this task. So far, there is no built-in tool with the ability to merge more than two PDF documents well on Windows.

SwifDoo PDF

With more than 30 features to address PDF-related problems, including how to add several PDF documents together, SwifDoo PDF is a full-featured PDF program on Windows 10, 8, and 7. This PDF merging tool doesn’t have a steep learning curve, so everyone can access the features without an effort. Here’s how to combine multiple PDF files with SwifDoo PDF:

Step 1: Download and install SwifDoo PDF from the official website;

Step 2: Open the program and click Open on the homepage;

Step 3: Select Merge from the Page menu. When the SwifDoo PDF Converter window pops up, select Add Files on the menu at the top to import multiple PDFs into the workstation;

Step 4: Specify the page range if needed. Once ready, click Start to combine PDFs into a single document.


Note: Besides being an effective PDF merging program on Windows 10, SwifDoo PDF is also an eligible PDF page organizer, which allows users to merge, split, extract, insert, and delete a page from a PDF. By doing so, SwifDoo PDF is a reliable PDF manager.

Foxit PDF Editor

As another Windows-based desktop PDF program, Foxit PDF also offers options for combining multiple PDFs. Foxit PDF supports adding PDFs from a folder, webpage, scanner, or clipboard to the workplace. Take a look at how to combine PDF files into one with Foxit PDF:


Step 1: Download the software and install it on your PC;

Step 2: Open Foxit PDF and choose Merge PDF from the Tool Wizard;

Step 3: Select Add Files to add more PDFs to the panel;

Step 4: When finished, click Combine Files to combine the selected PDFs.

Merging multiple PDFs into one document is not difficult with Foxit PDF. In addition, this desktop PDF merger integrates more features to allow users to add PDFs from other sources, such as a local folder or scanner.

The abovementioned PDF mergers are good at combining multiple PDFs into one document on Windows 10. Relatively speaking, combining two PDFs or multiple PDF files takes too much of your time. The good news is that you can minimize the program and let it run as a background process. It's way too time-saving and efficient, right?

How to Merge Multiple PDF Files into One on Mac

If you are looking for a solution to how to merge PDFs on a Mac device, then this section may be helpful. The built-in PDF viewer, Preview, is able to process different fundamental PDF-relevant tasks, such as editing, annotating, and combining.


No need for any external PDF software, Preview is an inbuilt PDF merging tool on Mac. Without needing to download or complete registration, users can easily combine multiple PDFs on Mac within a few steps:

Step 1: Open a PDF with Preview;

Step 2: Select Thumbnails from the View drop-down menu;

Step 3: Place your cursor on any thumbnail page where you want to insert a new PDF;

Step 4: Select Edit to choose Insert, and then press the Page from File;

Step 5: Choose Open to add a PDF to the current document. Once finished, choose File and then click Export as PDF to save it as a merged PDF.  

Although there are some professional PDF mergers available on Mac, I’m pretty sure Preview presents the easiest way to combine PDFs into one. If you need to combine more than two PDFs at the same time, repeat the above steps until you're done. Additionally, Preview can combine a portion of a PDF with another PDF; click this link for more information.
