Apple - How do I combine two or more images to get a single pdf file?

Here are the steps to save multiple images in Preview into a single multi-page PDF.

1. Select all of the images you want in your PDF, right-click and choose open with Preview

2. In Preview's Sidebar drag the images into the order you want them to appear in your PDF

3. Select/highlight all the images to be included in the PDF document; otherwise only a single image may end up the PDF document

4. Then from the "File" menu choose "Print Selected Images" (or "Print..." in recent OS X versions) and then "PDF > Save as PDF"

Use imagemagick.

• Install brew (https://brew.sh/)
• brew install imagemagick
• convert file1 file2 file3 output.pdf

files 1 through n can be any image or pdf file.

This can be done using Automator. Follow this steps:

• Create a new Workflow.
• Under Actions, Library, Files & Folders add the Get Specified Finder Items as a step.
• On the bottom of that step click on Add and select the images.
• Next, under Actions, Library, PDFs add the New PDF from Images. The workflow should look like the one on the image:

• Configure the step to your desire specifying among other things the location and name for the PDF file.
• Run the new workflow.
• In the Results tab of the New PDF from Images you now have your newly created PDF.
