Use these tips to combine PDFs on Mac or Windows devices.

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.

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.

How to combine PDFs on Mac

On Mac, you can combine PDFs with a built-in tool found in Preview, according to Apple Support.

Here’s how to combine two PDFs:

  • Open a PDF in Preview.
  • 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.
  • Click Edit > Insert > Page from File (if the Page from File selection is dimmed so you can’t click it, make sure that the file you have open is a PDF. Some encrypted PDF documents can’t be merged, according to Apple. Check the permissions of a PDF by choosing Tools > Show Inspector, then click the lock icon).
  • Select the PDF you want to add, and click Open.
  • Choose File > Export as PDF to save.

And here’s how to combine parts of one PDF with another PDF:

  • Open the PDFs you want to combine in Preview.
  • In each document, choose View > Thumbnails. You’ll see page thumbnails in the sidebar.
  • Press and hold the Command key, and select the page thumbnails that you want to add to the other document. Let go of the Command key.
  • Drag the selected thumbnails to the sidebar of the other PDF, and release where you want them to go. (If you have macOS Sierra or earlier, drag the thumbnails directly into a thumbnail in the other PDF.)

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

There are quite a few free options, as well as some good commercial ones:

Web-based (Free)

    Merge 2 PDF documents. Max 10MB/file. Limit of 20 merges/day . Merge up to 10 files. Max limit of 5MB/file. (Registration required)

Desktop tools (free)

Booklet Creater. Merges files to create a booklet. Rearranges pages to that you can print and fold to create a simple booklet.

PDF Sam. Also known as "PDF Split & Merge". FOSS tool for splitting and merging PDFs. Windows & Mac. Console and GUI interfaces. On Windows, the installer by default installs Ad-Aware Security Toolbar, sets Lavasoft SecureSearch as homepage, new tabs, and default search provider.

Swift PDF. Combines multiple images (JPG, GIF, etc.) into a single PDF.

Editor’s note, 5/1/2017: Swift PDF was last updated in 2006 and was compatible with Windows 95. The original link is dead and the product appears to no longer be supported. However, it is still downloadable at

pdftk. FOSS power tool. Command line only. Windows, Mac, Linux, FreeBSD. Windows GUI versions exist, including a portable version and the official free version.

Print the PDF one or two pages at a time. By printing in small batches, you can determine if a particular page, or an object on a page (such as an image), causes the problem. If you can identify a page or an object that does not print, do one of the following:

  • Remove the page or object.
  • Re-create the page or object that is causing the problem.
    Note: This option requires that you have the source file.
  • If you don’t have the source file, extract the page and try to print the page as an image. See Quick fix | Print PDF as image | Acrobat, Reader (cpsid_87345).

Reset the print settings to their defaults

Print by using the Acrobat default settings to determine if a print setting could have changed and is causing the problem.

Combine fragmented images to reduce the PDF file size

When you convert documents that contain transparent images into PDF files, the transparent images are processed in many small fragments in the PDF. A Word document containing a transparent GIF is an example. This processing can increase the file size of the PDF, which can cause printing problems. In Acrobat 8 and later, you can merge these fragments to reduce the PDF file size.

Merge or flatten layers in the PDF

PDF files can contain layered content if they are created from layered documents by using applications such as Adobe InDesign. As a result, a single page of the PDF file can contain different layers with different content. If you print a PDF that contains layered content, only the layer that is currently visible onscreen is printed. Acrobat Pro and Pro Extended let you specify which layer is visible and printable. Merge or flatten the layers in the PDF to determine if one of the layers is causing the printing problem.

Note: Merging or flattening layers can’t be undone. For this procedure, use a copy of your PDF.

To determine which version of Acrobat you are using, choose Help > About Adobe Acrobat (Windows), or Acrobat > About Acrobat (Mac OS).
