Also you can add more PDFs to combine them and merge them into one single. So, it works for all operating systems including Mac, Windows, and Linux.
To combine PDFs on the Mac, start with two or more source files. Double-click on the first file to open it in the Preview app, which is the default app for viewing PDF files in macOS. If you’ve installed third party software and Preview doesn’t open when you double-click on a PDF, you can force your files to open in Preview by right-clicking (or Control-clicking) on the files and selecting Open With > Preview. Once Preview is open and displaying your first PDF file, select Edit > Insert > Page from File from the menu bar at the top of the screen. You’ll see the familiar open/save dialog box appear to select your file from. Use the box to navigate to your second PDF file, select it, and then click the “Open” button at the bottom-right corner. The file, and any pages contained within it, will now appear in your PDF document.
To get an overview of the pages in your document and their order, select View > Thumbnails from the menu bar. A horizontal list of page thumbnails will appear on the left side of the Preview window. From here, you can click on individual or groups of pages to click and drag them into the desired order. If you need to delete a page, just select it from the Thumbnail list and hit the Delete key on your keyboard.

That’s all there is to it! The only other thing to know is that if you already have the sidebar on when you go to insert your pages, you can control where the new pages land by just clicking a thumbnail from the sidebar; the Edit > Insert > Page from File command will then put what you insert after whatever page you had clicked. But it’s so easy to move stuff around that you don’t really have to do that if you don’t want to!
I always forget to start there, but that’s just me and my Swiss-cheese memory. Want news and tips from TekRevue delivered directly to your inbox? Sign up for the TekRevue Weekly Digest using the box below. Get tips, reviews, news, and giveaways reserved exclusively for subscribers.

Drag the thumbnail of one PDF document (source) over of the thumbnail of the other PDF document (destination) and release the mouse or trackpad button when the pointer shows a green circle with a plus symbol in it. This will copy all pages from the source PDF and add them to the end of the destination PDF. If the pages in the destination PDF are shown in the wrong order, click the gray circle containing an arrow that appears over the PDF document's thumbnail, so that the arrow points to the right, and drag the thumbnails of the individual pages into the desired order. After the destination PDF contains all of the pages you want and the pages are in the correct order, you can select File > Save As to save a new PDF document containing all of the combined pages, or you can select File > Save to replace the original version of the destination PDF with the version containing the combined pages.
