Why Combine PDF Files?

There are many compelling reasons to merge PDF files. Consolidating your documents into a single file can offer significant advantages in terms of organization, sharing, and overall efficiency.

  • Easier Sharing: Instead of sending multiple files, you can share a single, comprehensive PDF. This simplifies communication and reduces the risk of missing attachments.
  • Improved Document Management: Keeping related documents together in one PDF enhances organization and makes it easier to find specific information when you need it. Having an organized virtual space translates to a more productive environment.
  • More Efficient Printing: Printing a single PDF is more straightforward than managing multiple print jobs. This saves time and reduces the potential for errors.
  • Organized Virtual Space: By combining scattered documents into a cohesive whole, you declutter your digital workspace, making it easier to navigate and manage your files efficiently. Fewer files means a less cluttered hard drive, improving overall system performance.

Methods to Combine PDFs on a Macbook

Using Preview (Built-in Mac App)

Mac's built-in Preview application provides a simple and free way to merge PDF files. This method is convenient for users who prefer not to install additional software for basic PDF management tasks.

Merging Two Complete PDFs in Preview

  1. Open the first PDF in Preview. Simply double-click the PDF file to open it with Preview.
  2. Enable Thumbnails Sidebar. Go to View > Thumbnails or press Option + Command + 2 to display the thumbnails of the PDF's pages in a sidebar.
  3. Select the page thumbnail. Choose the page thumbnail where you want to insert the second PDF. This is where the merged content will begin.
  4. Insert the second PDF. Go to Edit > Insert > Page from File. Select the second PDF file you want to merge and click Open. The second PDF will be inserted after the selected page.
  5. Save the merged document. Go to File > Export as PDF. Choose a name and location for the merged PDF file and click Save.

Merging Part of a PDF with Another in Preview

  1. Open both PDFs in Preview. Open both the source PDF (containing pages you want to extract) and the destination PDF (where you want to insert the pages).
  2. Enable Thumbnails Sidebar in both documents. Ensure the thumbnail sidebar is visible in both Preview windows by going to View > Thumbnails.
  3. Select the thumbnails you want to add. In the source PDF, select the thumbnails of the pages you wish to merge into the destination PDF. Use Command-click to select multiple non-adjacent thumbnails, or Shift-click to select a range of adjacent thumbnails.
  4. Drag the selected thumbnails to the sidebar of the other PDF. Click and drag the selected thumbnails from the source PDF's sidebar to the destination PDF's sidebar.
  5. Drop them in the desired location. Position the cursor in the destination PDF's sidebar where you want to insert the dragged pages and release the mouse button. The pages will be inserted at that location.

Using Finder Quick Actions

Finder Quick Actions offer another convenient way to combine PDFs and images directly from your desktop or a Finder window. This method is particularly useful for quickly merging a selection of files without opening any applications.

  1. Select the files. On your desktop or in a Finder window, select all the PDF and image files you want to combine. You can select multiple files by holding down the Command key while clicking on each file.
  2. Control-click the selected files. Right-click (or Control-click) on any of the selected files to open the context menu.
  3. Choose "Quick Actions > Create PDF." From the context menu, select Quick Actions, then choose Create PDF. This option will combine the selected files into a single PDF.
  4. The file is created automatically. The new PDF file will be automatically created in the same location as the original files. The filename will be similar to the name of the first file you selected.

Other Methods (Briefly Mention)

While Preview, Finder Quick Actions, and BreezePDF offer straightforward solutions, other methods are available for combining PDFs on a Macbook, each with its own set of features and limitations.

Adobe Acrobat Online (Free and Paid Options)

Adobe Acrobat Online offers both free and paid options for merging PDF files. The free version provides basic functionality, while the paid subscription unlocks advanced features and removes limitations on file size and the number of merges you can perform.

Tips and Considerations

When combining PDF files, there are a few key considerations to keep in mind to ensure a smooth and efficient process. Paying attention to these details can help you achieve the desired results and avoid potential issues.

  • File Order: Files are often combined in the order they are selected. Preview and BreezePDF give more control of order. Double-check the sequence before merging to ensure the final document flows logically.
  • Large Files: Compressing large combined files can make them easier to share via email or upload to online platforms. Many PDF editors, including BreezePDF, offer compression options.
  • Splitting PDFs: You can split PDFs after combining them, if needed. This can be done using Preview or BreezePDF.

Combining Images into One PDF

Sometimes, you may need to combine a series of images into a single PDF document. This can be particularly useful for creating portfolios, presentations, or archival documents. Preview provides a simple method for achieving this.

  1. Open the images in Preview. Select all the images you wish to combine and open them with Preview. All selected images will open in a single Preview window.
  2. Select all the images. In Preview, make sure all images are selected (Command+A).
  3. Print to PDF. Go to File > Print. In the print dialog, select "Save as PDF" from the PDF dropdown menu in the lower-left corner. This will combine all the selected images into a single PDF document.
