How to Combine Multiple PDF's Into One

How To Combine Multiple PDF's Into One (Using Adobe Acrobat)
STEP 1 - Install the full version of Adobe Acrobat. Most computers have Adobe Reader or Acrobat Reader, but Acrobat was created specifically for editing and managing PDFs. As of 2015, the only Adobe product that can merge PDFs is the paid program Adobe Acrobat DC. However, many computers come with the program pre-installed. If not, you'll need to buy it or move on to the online method at the very bottom.
  • If you are not sure if you already have Acrobat DC, right-click (PC) or Ctrl-click (Mac) on the one of your PDF's and hover over "Open With." All PDF compatible programs will appear.
  • While Adobe now charges for Acrobat, you can download a 30-day trial that will let you merge PDFs immediately if you are in a pinch.

STEP 1 - Use a free PDF merging program if you need to combine lots of PDFs, or need to work offline. These programs are simple to use, acting almost exactly like their online counterparts. The good news is that they are generally free. However, like all programs downloaded from the internet, they carry some risk when downloading. Only use sites you trust.
