Why Combine PDF Files?

There are numerous reasons why you might need to combine PDF files. Understanding these benefits can highlight the importance of mastering these techniques.

  • Easier Sharing: Sharing one file is always simpler than sharing many. Consolidating related documents into a single PDF makes distribution and collaboration much more manageable.
  • Improved Document Management: Managing a large number of individual files can become cumbersome. By combining related PDFs, you can streamline projects and reduce clutter in your digital workspace.
  • Efficient Printing: Printing a single, combined document is far more convenient than printing multiple individual files. This saves time and reduces the risk of misplacing pages.
  • Enhanced Organization: Consolidating documents contributes to a more organized digital environment, making it easier to find and access the information you need when you need it.
  • Easier Review: Reviewing documents as one cohesive unit allows for a more efficient and comprehensive assessment. It facilitates better understanding of the overall content and context.

Combining PDFs Using Mac's Built-in Tools

macOS offers several built-in tools that you can leverage to combine PDF files without needing to install any additional software. These tools, such as Preview, Finder Quick Actions, and Automator, provide versatile options for merging documents.

Using Preview

Preview is the default PDF viewer on macOS and a powerful tool often overlooked. It provides a simple yet effective way to combine PDF files. Preview is already installed on your Mac, making it a convenient and readily available solution for your document management needs.

  1. Open the PDFs you want to combine in Preview.
  2. Enable the Thumbnails sidebar by navigating to View > Thumbnails (or use the shortcut Option + Command + 2).

Merging Entire PDFs:

  1. In the Thumbnails sidebar, select the page where you want to insert the other PDF.
  2. Navigate to Edit > Insert > Page from File.
  3. Select the PDF file you want to merge. The selected PDF will be inserted after the chosen page.
  4. Save the merged document by navigating to File > Export as PDF.

Merging Select Pages from a PDF:

  1. Open the PDF you want to extract pages from in Preview.
  2. In the Thumbnails sidebar, select the page or pages you want to extract.
  3. Drag and drop the selected pages to your desktop or another folder to create separate PDF files.

Reordering Pages in Preview:

Preview also allows you to easily reorder pages within a PDF. In the Thumbnails sidebar, simply drag and drop the pages to rearrange them in the desired sequence. This feature is particularly useful when you need to organize the content of your combined document.

Using Finder Quick Actions

Since Mojave, macOS offers Finder Quick Actions, providing a convenient way to combine PDFs directly from Finder. This method is particularly useful when you want to quickly merge several files without opening any applications.

  1. Select the files you want to combine into a PDF. The files will appear in the combined PDF in the same order you select them.
  2. Control-click the selected files, then choose Quick Actions > Create PDF.
  3. If you don’t see the Preview pane on the right, choose View > Show Preview.
  4. The file is created automatically with a name similar to the first file you selected.

Using Automator

Automator is a powerful macOS application that allows you to create custom workflows for automating various tasks, including combining PDF files. This method is ideal for users who need to perform this task regularly and want a more automated solution.

  1. Launch “Automator,” found in the “Applications” folder.
  2. Click “New Document” when Automator opens.
  3. Select “Workflow” and click “Choose.”
  4. Search for and drag the “PDFs” category to the right-hand pane in the Actions Library on the left.
  5. Find and drag “Combine PDF Pages” to the workflow area on the right from the list of actions.
  6. Click “Add” in the “Combine PDF Pages” action to add the PDFs you want to merge.
  7. Arrange the PDFs in the desired sequence by dragging them up or down in the list.
  8. Choose where to save the combined PDF by clicking “Options” and setting the output folder.
  9. Run the workflow by clicking the “Run” button in the top-right corner of the Automator window.
  10. A new combined PDF file will be created and saved to the specified location.

Splitting in Preview:

  1. Open the PDF in Preview.
  2. Enable the Thumbnails sidebar.
  3. Select the pages you want to separate.

Additional PDF Tasks

Beyond combining and splitting PDFs, you might need to perform other tasks to manage your documents effectively. These tasks include compressing large files and converting various document types to PDF.

  • Compressing large PDF files (consider using a dedicated compression tool; also see how to add fields to PDFs for free, which may reduce file size).
  • Converting images to PDFs and then merging.
  • Converting other document types (Word, Excel) to PDF and then merging.
  • Saving specific pages from a PDF
