There are times you may want to join two or more PDF files together into a single PDF. In a previous post, we discussed how to combine multiple PDFs using Preview on Mac. In fact, you can directly merge several PDFs in Finder without even opening any PDF apps. Here’s how to do that.
Launch Finder on Mac, browse to the location where the PDF files you want to combine are saved. Rename the PDF files, say 1.pdf, 2.pdf, 3.pdf, to organize them into the right sequence. Drag to select all the PDFs, or press and hold the Shift or Command key when clicking the PDFs to choose multiple PDF files. Then right click on one of them, or press and hold Control key and click on the PDFs, the contextual menu pops up. Choose Quick Actions > Create PDF.
A new PDF file will be created and saved to the same folder as the original PDF documents. This is probably the easiest way you can merge several PDF files on Mac.
