A powerful feature of Adobe Acrobat is the ability to combine several different types of documents into a single Portable Document Format file. You may want to do this when you need to distribute several different types of documents. By creating one PDF that contains them all, you can virtually ensure that each recipient will be able to view everything because PDF documents are compatible with practically all operating systems.
Launch Adobe Acrobat on your system.
Click “File” in the top menu bar, then hover your mouse over “Combine” from the drop-down menu that appears.
Click the “Add Files” drop-down menu in the upper left-hand side of the “Combine Files” dialog box. Click the “Add Files” button.
Navigate to the directory containing the file that you would like to add using the Windows Explorer box that appears. Double-click the file to select it.
Repeat the process until you have added all of the files to the “Combine Files” dialog box.
Click “Combine Files” to finish the process. All documents will open in their native program, then will be automatically converted to PDF.
Type a name for your new PDF document when prompted and click “Save.”
