Combining pdf documents on an Apple computer is easy.
There are lots of websites offering software to merge PDF files, but you don’t need a third party program to do it. It’s built right in to OS X for free.
OS X comes with a free application called ‘Preview’ that will open automatically whenever you click on a pdf file. It turns out that Preview can edit and merge pdf files!
Exactly how you do this varies depending on which version of OSX that you have. The concept is the same but the step by step pictures will look slightly different.
Please click on the version of OSX that you have to find out how to merge a pdf file:
For all versions of OS X prior to Mountain Lion (10.7 and earlier) just follow the instructions below.
To join two or more pdf files together using Preview:
1 Open the pdf file in preview.
2. Open the thumbnail view (Shift-⌘-D)
3. Drag a second pdf ON TOP OF an existing page thumbnail.
When you drag in step 3 it must drag to on top of the thumbnail, as in over it, not above it.
This is a bit hard to explain, the best way to grasp the concept is to look at the pictures below.
SUMMARY: To combine two separate PDF files into one document you need to drag the new pdf ON TOP OF an existing thumbnail until the grey border appears – then it will merge the two pdfs together. (You can then save the new merged pdf.)
If you drag it into the sidebar but not on top of an existing page the new file will be added as an external link – not merged into the original pdf document.
