Leopard and Snow Leopard have the ability to edit pdf files, move pages around, and even merge pdf documents together. In OS X combining pdf documents is now easy and you don’t need a third party program to do it! Here is how to join two or more pdf files together into one.

1. Open the first pdf file in Preview.

2. Now select ‘Sidebar’ from the ‘View’ menu – this will make a thumbnail sidebar appear.

3. You can now drag the second pdf file into this sidebar window, and it will be added to your pdf document as an additional page.

NOTE: In Snow Leopard you need to drag the new pdf ON TOP OF the existing pdf’s thumbnails ( a little red box shows you that you are doing this).

This signals that you want to add it to the document. You can then move it to where you like.

If you drag it into the sidebar but not on top of an existing page it will appear as a red line instead of a box and the file will be added as a link, but not merged within the pdf document.

You can now save it!
