With Mountain Lion (OSX 10.8) Apple have made it even simpler to join two pdf files together – you just need to drag any pdf file into the thumbnail window of an existing pdf file and the two will be merged together!
Note: this is different for different versions of OS X.

I have just downloaded a PDF magazine. It comes as double pages. That is, the first page is a single A4 portrait page, the second and third pages are two a4 pages combined into an A3 landscape page, and so on. Now I have tried to view it on a number of ebook readers on the iPad but non of them can handle two pages side by side. I want to read in portrait mode, and read one page at a time.
In portrait mode if I view a double page it squishes it up to take just half the screen. If I zoom in, the zoom resets back to small when I change to the next page.
There seem to be hundreds of ebook readers out there. Anyone found one that handles double a4 pages?
(I’ve tried iBooks, Kindle, Blio, Kobo and iPdf and none of them work!)
Depending on what program you used to create a PDF, the file size of your PDF file can be quite large. If you combine two or three PDF files together using preview, you can also end up with a bloated PDF file. The best way to reduce PDF file size is with Acrobat professional, which can do all sorts of magic on PDF files. Sadly we can’t all afford Acrobat Professional, so here is a free way to make a PDF file smaller.
Reduce file size will degrade your photo quality. Use it wisely.
Thanks so much. Your explanation is brilliant. Easy to follow. Better than apple support itself. :)
OS X comes with a free application called ‘Preview’ that will open automatically whenever you click on a pdf file. Preview can edit and merge pdf files but the official Apple instructions are not quite right. Here’s how to do it depending on which version of OS X that you have.
The basic concept for merging 2 pdf files is the same for whatever version of OS X you have. You open the first file, view the page thumbnails, then drag the second file into the first file and save the new file. Exactly how this works varies depending on which version of OS X that you have. Apple have changed the details a few times. Sometimes there’s a green plus sign to indicate the merge. Sometimes there’s a grey border. If you don’t get it right the 2 files will not merge. You need to read the directions for the exact OS version that you have. (To find out which version of OS X you have just go to the Apple Menu and click ‘about this mac.’)
