Adobe Acrobat: Merging PDF FIles

You can combine multiple PDF documents or a wide variety of file types, including spreadsheets, images, and emails. 

1. Open the Combine files tool:  
   Open the Combine Files tool using the shortcut in the right pane or from the Tools center, accessed at the upper left. 
   
   
   
   
2. Add files to combine: Choose from various file types – multiple PDF files, Microsoft Word documents, Excel spreadsheets, Microsoft PowerPoint presentations, images, email, and more – to merge into one PDF.
   a. Select Add Files and navigate to the location of the files you want to add. You can add files or a folder from your computer, or add content directly from a scanner, web page, or your Clipboard. 
   
   
   
   b. Select one or more files to add. Click the "Add Files" button. 
   
   
   
   
3. Repeat these steps as many times as necessary to include the content you would like to combine into your final PDF. Alternatively, you can drag files you want to combine directly from your desktop or file system.
