The DMG file extension was specifically designed for Macintosh computers and users are likely to have a lot of trouble if trying to use them on a Windows device. There may be instances where one can convert the files, but it probably needed to look for additional utilities that will allow the file to be accessed from the chosen device. All these apps let you combine PDFs in basically the same way. Here's how PDF-XChange Editor does it. The simplest method is to use File New Document, and choose the option to Combine Files into.

Choose Tools > Combine Files. The Combine Files interface is displayed with the toolbar at the top.

Drag files or emails directly into the Combine Files interface. Alternatively, choose an option from the Add Files menu. You can add a folder of files, a web page, any currently open files, items in the clipboard, pages from a scanner, an email, or a file you combined previously (Reuse Files).

Note:

If you add a folder that contains files other than PDFs, the non-PDF files are not added.

In the Thumbnail view, drag-and-drop the file or pageinto position. As you drag, a blue bar moves between pages or documentsto indicate the current position.

In the Thumbnail view, hover over the page or file and then click the Expand pages thumbnail . In expanded view, you can easily move the individual pages among the other pages and documents.

To collapse the pages, hover over the first page and then click the Collapse Document thumbnail .

In the Thumbnail view, hover over the page, and then click the Zoom thumbnail .

In the Thumbnail view, hover over the page and then click the Delete thumbnail .

In the List view, click the column name that you wantto sort by. Click again to sort in reverse order. The order of filesin the list reflects the order of the files in the combined PDF.Sorting rearranges the pages of the combined PDF.

In the List view, select the file or files you want to move. Then click the Move Up or Move Down button.

Click Options, and select one of the file size options for the converted file:

Reduces large images to screen resolution and compresses the images by using low-quality JPEG. This option is suitable for onscreen display, email, and the Internet.

Note: If any of the source files are already PDFs, the Smaller File Size option applies the Reduce File Size feature to those files. The Reduce File Size feature is not applied if either the Default File Size or Larger File Size option is selected.

Create PDFs suitable for reliable viewing and printing of business documents. The PDF files in the list retain their original file size and quality.

Creates PDFs suitable for printing on desktop printers. Applies the High Quality Print conversion preset and the PDF files in the list retain the original file size and quality.

Note:

This option may result in a larger file size for the final PDF.

In the Options dialog box, specify the conversion settings as needed, then click OK.

When you have finished arranging the pages, click Combine.

A status dialog box shows the progress of the file conversions.Some source applications start and close automatically.

Working with PDFs can be tricky, especially if you're trying to merge multiple documents together. Maybe you're constructing a portfolio, or maybe you just want to reduce file clutter. Whatever the reason, it can be confusing to keep lots of documents straight, but it's also tricky to figure out how to bring them together.

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.

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.
