How do I combine two or more images to get a single pdf file? Say I have some image files (for instance, the result of scanning some sheets) and I want to combine them into a single pdf file, each image on a different page.
Is there a faster / more convenient way than converting each one to a pdf file and then combining those (say, as explained here)? Or, if this is more or less how it is to be done, which is the most intelligent and less tedious possible way to do it?
Here are the steps to save multiple images in Preview into a single multi-page PDF.


Select all of the images you want in your PDF, right-click and choose open with Preview
In Preview's Sidebar drag the images into the order you want them to appear in your PDF
Select/highlight all the images to be included in the PDF document; otherwise only a single image may end up the PDF document
Then from the "File" menu choose "Print Selected Images" (or "Print..." in recent OS X versions) and then "PDF > Save as PDF"
