Why Merge PDFs?

Merging PDF files offers numerous advantages that streamline document management and enhance productivity. One of the primary benefits is the simplification of file sending and sharing. Instead of sending multiple individual files, you can combine them into a single, easily manageable document. This consolidation also makes it easier to compress the file for emailing, especially when dealing with size limitations.

Improved organization is another significant advantage of merging PDFs. By combining related documents, you can create a structured and cohesive file, making it easier to find and access information. Consider scenarios like compiling financial documents for tax season, consolidating receipts for expense reports, or assembling project pages and notes into a single comprehensive file. These examples highlight the practical benefits of merging PDFs in various situations.

Method 2: Free Desktop Apps (PDF Merger & Splitter)

Since Windows 11 lacks a native PDF merge feature, third-party desktop applications offer a viable alternative. These apps are installed directly on your computer, allowing you to perform PDF merging tasks offline. However, it's essential to choose reputable applications to ensure the security and privacy of your documents. Let's explore PDF Merger & Splitter (by AnywaySoft) as a representative example.

Here's a guide on how to use PDF Merger & Splitter:

  1. Installing the App: Begin by installing PDF Merger & Splitter from the Microsoft Store. The installation process is straightforward and typically completes within a few minutes.
  2. Launching the App and Selecting "Merge": Once installed, launch the application and select the "Merge" option from the main menu. This will open the merging interface.

  4. Reordering Files: Use the "Move Up" and "Move Down" buttons to arrange the files in the desired order. Ensuring the correct order is crucial for a logically organized merged PDF.
  5. Previewing Files (Optional): Some apps offer a preview feature, allowing you to view the files before merging them. This can help you confirm that you've added the correct documents and arranged them properly.
  6. Merging and Saving the File: Click the "Merge" or "Combine" button to start the merging process. Once complete, save the merged PDF to your desired location on your computer.

Many tools also allow splitting and customization of documents. This functionality is similar to creating a fillable word document which can then be converted.

Method 3: Online PDF Mergers (Adobe Acrobat Online, iLovePDF, Smallpdf)

Online PDF mergers provide a convenient way to combine PDF files without the need to install any software. These tools are accessible through your web browser, allowing you to merge PDFs from anywhere with an internet connection. However, it's crucial to exercise caution when using online PDF mergers, particularly when dealing with confidential files. Always opt for reputable sites with strong security measures to protect your data.

Let's explore how to use Adobe Acrobat Online to merge PDFs:

  1. Access the Tool: Navigate to the Adobe Acrobat Online merge tool in your web browser. This will open the merging interface.
  2. Upload Files: Upload the PDF files you want to merge by either dragging and dropping them into the designated area or selecting them from your computer.

  5. Download the Merged File: Once the merging is complete, download the merged PDF to your computer.

Other options like iLovePDF and Smallpdf are available with similar processes. Ensure to download the final document immediately after combining to avoid any chance of deletion from the server.

Method 4: Command Prompt (Ghostscript)

For advanced users, Ghostscript offers a command-line tool for PDF manipulation, including merging. This method requires some technical expertise but provides a powerful and flexible way to combine PDF files. Ghostscript is a free and open-source software suite that can perform various tasks, including converting, merging, and manipulating PDF documents. It also can be used to create fillable forms.

Here are the steps to merge PDFs using Ghostscript:

  1. Download and Install Ghostscript: Download and install Ghostscript from its official website. Ensure you download the appropriate version for your operating system.
  2. Open Command Prompt as Administrator: Open the Command Prompt as an administrator. This is necessary to ensure you have the required permissions to execute the commands.
  3. Navigate to the Directory: Use the `cd` command to navigate to the directory containing the PDF files you want to merge. For example, if your files are in `C:\PDFs`, type `cd C:\PDFs` and press Enter.
  4. Execute the Merging Command: Use the following command to merge the PDF files:
    gswin64c -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=Combined.pdf File1.pdf File2.pdf

The parameters used in the command are as follows:

  • `dBATCH`: Instructs Ghostscript to process the files in batch mode.
  • `dNOPAUSE`: Prevents Ghostscript from pausing after each file is processed.
  • `q`: Enables quiet mode, suppressing unnecessary output.
  • `sDEVICE=pdfwrite`: Specifies the output device as a PDF writer.

The new file will be located in the directory you navigated to. Although complex, it allows for adding fillable form fields in PDFs

Beyond basic merging, BreezePDF allows for rearranging pages within the merged document, adding, deleting, and rotating pages. These features are not always available in other free tools, adding an additional level of control to your merged file. When used in conjunction with other features, you can create fillable forms in SharePoint.
