Step-by-step

Merge multiple PDFS into one

1 Copy the PDFS

It is best to work with a copy of the PDFS rather than the original files because some actions can change them. Create a new folder and then copy the documents to it.

2 Select PDF files

Select the PDF files you want to combine by cmd+clicking them. It can be some or all of them. Notice that you can browse a PDF’S pages by clicking the arrows on it.

3 Create a PDF

Ctrl+click any of the selected PDFS in the folder and select Quick Actions>create PDF. This creates a new PDF by combining the existing PDF files into one.

4 Name the PDF

A new file appears in the folder and whatever name it is given, you will probably want to rename it to reflect the combined contents. Select it, press enter and name it.

5 Open in Preview

The previous method is quick and easy, but you cannot control the order in which the PDFS appear in the new PDF. Instead, ctrl+click a PDF and open it in Preview.

6 Shrink the sidebar

All the PDFS appear in separate Preview windows. Show the sidebar if it is hidden and then collapse the page thumbnails to one using the button at the top of the sidebar.

7 Drag and drop

Choose which PDF should appear first in the new merged PDF and then click and drag the PDF thumbnail from the sidebars of the other windows and drop them to add them.

8 One by one

Alternatively open just the first PDF document in Preview. Then drag the other PDFS one by one from the Finder window and drop them in the Preview sidebar.

9 Rename the file

Add all the other PDF documents to the first one in the order in which they should appear. Click the name in the title bar of the window and give the document a new name.
