How to combine PDF files into one document on Mac with third-party tools

For merging PDF files, Preview is the easiest option to use. But if you have to deal with tons of PDFs daily, using Preview won’t be enough. Here is when dedicated editing software will come in handy.

Combining PDF files is a core feature of any PDF editor. The most popular one is Adobe Acrobat, which has been the driving force behind PDFs for many years. Yet, more intuitive and easy-to-use apps are coming into play these days. For instance, as the name suggests, PDF Expert is great at performing PDF-related operations on Mac.

Both Adobe Acrobat and PDF Expert are paid but offer a free trial. Check them out and choose which one suits you the most.

Need extra help with your Mac performance?

Every Mac needs a little troubleshooting support from time to time. System junk, old cache, and numerous useless files — all these can decrease Mac’s speed and make apps fail, including Preview and other PDF editors.

If your computer regularly malfunctions, perhaps it’s time to clean it up from months-old clutter. CleanMyMac X is a powerful junk-cleaner with a bunch of features designed to solve Mac-specific issues. Here’s how to use it:

1. Download CleanMyMac X — get it here for free.
2. Launch the app and choose System Junk in the sidebar.
3. Press Scan, and then Clean.

Additionally, I recommend using the Maintenance tab. Run the ‘Free Up RAM’ and ‘Run Maintenance Scripts’ tools to optimize your system’s performance and enhance the quality of your user experience.

Merging PDF files is no difficult task with Preview. You can use other tools as well, but as for me, Preview is really quick and gets the job done in a few seconds. For super-fast performance, I recommend optimizing your Mac with CleanMyMac X and deleting junk and cache once in a while.

Trying to merge multiple PDFs together? Don't get stressed. Though working with lots of different documents can get tricky, there are a few easy ways you can combine PDFs together, whether you're constructing a portfolio or just looking for ways to cut down on file clutter.

Step 1 - Download PDFBinder.

One of the most popular tools for combining PDFs is Adobe Acrobat, but that software will cost you at least $13 a month for a subscription. Luckily, there are a few other ways you can combine PDFs for free, no matter what type of computer you're using.

Here's how to combine multiple PDFs for free, whether you're working on a Windows device or a Mac. (We've also got tricks for how to easily sign PDFs, and four free apps for better PDF editing.)

How to combine PDFs on Windows

If you're using Windows, you'll need a third-party app to help you combine PDFs. We tested a few, and found a solid option in PDF Merger & Splitter by AnywaySoft. It's available through the Microsoft Store for free.

Here's how to merge PDFs with this app:

• Open the app, and choose Merge or Split. If you just need to merge two documents without changing the order of any pages, choose Merge.
• Click Add PDFs, and select however many you want to merge. You have the option to move them up or down, or sort by name. You can also preview what the merged documents will look like.
• Once your documents are in order, hit Merge, and name and save the new merged PDF.

If you want to customize your merger a bit more, such as by changing the order of pages or only adding in certain parts of each PDF, you'll have to split them first. To do that, select Split when the app opens. Choose which individual pages or page ranges you want to pull out. You can save them as one PDF, or as individual PDFs.

• Go to View > Thumbnails. You'll see page thumbnails in the sidebar.
• Select the thumbnail for the page where you want to insert the other document.

You can rotate, delete and reorder pages from the thumbnail section, too.
