Finally, efficient storage is achieved by minimizing the number of files, optimizing your digital space and potentially reducing storage costs.

Method 2: Using Free Desktop Apps

Windows users often turn to third-party desktop applications to handle PDF merging, since it is not a built in feature. Several free applications are available that provide robust PDF merging capabilities. These applications usually require installation on your computer, offering offline functionality and advanced features, although installation may take some time.

PDFsam Basic is a popular choice. It allows users to merge PDF files, specify page ranges, add blank pages, and insert footers. A unique "Alternating Mix" feature combines two PDFs, alternating pages from each file. PDFsam Basic is compatible with both Windows and macOS.

PDF Merger & Splitter (AnywaySoft) can be installed from the Microsoft Store. This UWP (Universal Windows Platform) app enables you to preview files. It allows you to set page sizes while merging PDFs, offering a convenient and modern interface.

Method 3: Using Online PDF Merging Tools

Online PDF merging tools provide a convenient alternative, allowing you to combine PDFs directly through your web browser. This eliminates the need for software installation, offering quick and accessible merging capabilities. However, it's crucial to exercise caution and use reputable sites due to privacy concerns associated with uploading sensitive documents online.

Adobe Acrobat Online is a trusted option. It guides you through uploading, reordering, merging, and downloading your combined PDF. Other reliable online platforms include iLovePDF and Smallpdf, offering similar merging services with various additional PDF-related tools.

Method 4: Using Command Prompt (Ghostscript)

For advanced users, the Command Prompt with Ghostscript provides a powerful method for combining PDFs. Ghostscript is a free tool that offers extensive PDF manipulation capabilities, including merging. This method requires a basic understanding of command-line syntax and is suitable for users comfortable with technical procedures.

Here’s how to use it:

  1. Download and Install Ghostscript: Download Ghostscript from its official website and follow the installation instructions.
  2. Open Command Prompt as Administrator: Open Command Prompt with administrative privileges to ensure the necessary permissions.
  3. Navigate to the PDF Folder: Use the `cd` command to navigate to the directory containing the PDF files you wish to merge.
  4. Execute the `gswin64c` Command: Use the following command to merge the files:

`gswin64c -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=merged.pdf file1.pdf file2.pdf file3.pdf`

The parameters `-dBATCH` and `-dNOPAUSE` ensure the process runs without interruption. The parameter `-q` suppresses unnecessary output, and `-sDEVICE=pdfwrite` specifies the PDF output device. The parameter `-sOutputFile` defines the name of the merged PDF file. Locate the merged PDF file in the same directory where the original files are located.

Considerations when Combining PDFs

Before combining PDFs, consider potential formatting issues that might arise during the process. Complex layouts, embedded fonts, or interactive elements may not translate perfectly when merged, leading to unexpected changes in appearance. Also, check for limitations on file size and the number of files that can be processed. Some tools impose restrictions on these factors, potentially affecting the usability of large or numerous documents.

What to do after combining PDF files

After combining your PDF files, you might need to perform additional operations. Splitting a combined PDF back into individual files can be useful for isolating specific sections or pages. Adobe Acrobat offers a splitting feature. However, with BreezePDF, you can combine multiple PDF files seamlessly, and you'll be able to also make PDF editable. Check it out today!
