Arrange PDFs

Preview can merge PDFs and manage pages pretty easily. To delete a page, the simplest way is to use the sidebar’s Contact Sheet view, select the page, press

and then save the file. To merge pages from one PDF into another, open both and have their windows side by side and in Contact Sheet view. In one window, select the pages you want to move, drag them into place in the other document’s window, and then save that second document. Alternatively, if you want to merge an entire PDF into another, open one, drag the second file from Finder into the Contact Sheet view, and then save the combined document.
