Why Merge PDF Files?

Combining PDF files offers numerous advantages that streamline your workflow and enhance document management. One of the primary benefits is easier sharing. Instead of sending multiple attachments, you can consolidate all related documents into a single PDF file, simplifying email communication and file transfers. This approach ensures that recipients have all the necessary information in one convenient document.

Improved document management is another compelling reason to merge PDFs into one Mac. Projects often involve numerous related documents, and consolidating these files into a single, well-organized PDF makes it easier to keep track of all the components. This streamlines the review process and simplifies collaboration, ultimately improving overall productivity. It also helps to reduce clutter on your hard drive, making it easier to find the files you need when you need them.

Efficient printing is yet another significant benefit. When you need to print multiple documents, combining them into a single PDF allows you to print them as a single batch. This not only saves time but also ensures that the documents are printed in the correct order, preventing any potential confusion or misfiling. By consolidating related documents, you create a more organized and manageable workflow.

Methods to Combine PDFs on Mac

A. Using BreezePDF

BreezePDF provides a user-friendly and secure way to merge PDFs into one Mac directly within your browser. Unlike many other PDF editors, BreezePDF operates entirely on your device, ensuring that your documents are never sent to a server. This 100% private approach guarantees the confidentiality of your sensitive information, making it an ideal choice for merging confidential or proprietary documents.

Here's a step-by-step guide on how to merge PDF files using BreezePDF:

  1. Simply access the BreezePDF website. There's no need for any sign-up or download.
  2. Locate the merge PDF function.
  3. Upload all the PDF files you wish to combine.
  4. Rearrange the PDF files in your desired order if required.
  5. Click the button to merge the PDF files.
  6. Download your merged PDF.

B. Method 1: Combining PDFs with Preview

Preview, the default PDF viewer on macOS, also offers a way to merge PDFs into one Mac, though it can be slightly less intuitive than using a dedicated tool like BreezePDF.

  1. Open one of the PDF documents in Preview.
  2. Enable the Thumbnails sidebar by selecting "View > Thumbnails".
  3. In the sidebar, select the page where you want to insert the other PDF.
  4. Go to "Edit > Insert > Page from File" and select the PDF file you want to merge.
  5. Repeat steps 3 and 4 for any additional PDFs.
  6. Once all PDFs are merged, save the document by selecting "File > Export as PDF".

Combining Part of a PDF with Another

  1. Open both PDFs in Preview
  2. Select View > Thumbnails
  3. Press and hold the Command key (⌘)
  4. Drag Selected Thumbnails into the sidebar

C. Method 2: Combining Files via Finder Quick Actions

macOS Finder provides a quick way to merge PDFs into one Mac, although it offers limited control over the order of the merged documents.

  1. Select all the PDF files you want to combine. Ensure they are selected in the desired order, as the order of selection determines the order in the merged PDF.
  2. Control-click (right-click) on the selected files.
  3. Choose "Quick Actions > Create PDF".

D. Method 3: Using Adobe Acrobat Online Tools

Adobe Acrobat Online tools provide a web-based solution to merge PDFs into one Mac.

  1. Go to the Acrobat online merge tool.
  2. Drag and drop your PDF files or select them from your computer.
  3. Reorder the files as needed.
  4. Click "Merge Files".
  5. Download the merged PDF document.

E. Method 4: Combining PDFs using Automator

Automator, a built-in macOS application, allows you to create custom workflows, including one for merging PDFs. While powerful, this method is generally more complex than using BreezePDF or Preview and requires some technical knowledge.

  1. Launch Automator.
  2. Create a new workflow by selecting "File > New" and choosing "Workflow".
  3. Add the "Combine PDF Pages" action to your workflow.
  4. Add the PDF files you want to merge to the action.
  5. Run the workflow by clicking the "Run" button.

Consider using BreezePDF, it's much easier!

What To Do After Combining PDFs

After you merge PDFs into one Mac, there are several post-processing steps you might want to consider. Compressing the new file can reduce its size, making it easier to share via email or store on your device. There are online tools and macOS utilities that can compress PDFs without significantly compromising their quality.

Splitting PDFs after combining them might seem counterintuitive, but it can be useful if you realize you need to extract specific pages from the merged document. Preview allows you to easily split PDFs by dragging and dropping thumbnails of the pages you want to extract onto your desktop or into a new folder. Use the features we provide at Create Fillable PDF.

  1. Open the PDF you wish to split in the Preview app on your Mac.
  2. Open the thumbnail view and select the page or pages you would like to separate.
  3. Drag and drop the pages to your desktop or to another folder.
  4. You can continue to split the PDF by repeating the last two steps.

Reordering PDF pages can also improve the flow and organization of your document. Preview provides a simple drag-and-drop interface for reordering pages within a PDF, allowing you to easily rearrange the content to meet your specific needs.

Troubleshooting Common Issues

While merging PDFs is generally a straightforward process, you might encounter some common issues. One frequent problem is file size limitations when using online tools. BreezePDF, since it operates locally, does not have such limitations. Another issue can be password-protected PDFs. These must be unlocked before merging and you can password protect afterwards using the password protect PDF feature. If you have files you need to convert to fillable PDF, we have a great tool for that at Adobe Acrobat Pro DC: Create Fillable Form.

Conclusion

Combining PDF files into a single document is a common task with various solutions available on macOS. While Preview, Finder Quick Actions, Adobe Acrobat Online Tools, and Automator offer different approaches, BreezePDF stands out as a user-friendly, secure, and private solution. By operating entirely on your device, BreezePDF ensures the confidentiality of your sensitive information, making it an ideal choice for merging confidential documents.
