How to Merge Multiple PDF Files into One

From a PDF file, you can split or extract individual pages to separate PDF files natively using the Microsoft Print to PDF printer. But, to combine multiple PDF files into a single PDF, there is no built-in solution. This article explains how to merge two or more PDF files into one using third-party software.

How to Combine or Merge Multiple PDF Files into One

There are several websites that can merge or combine PDF files for you. But, if you need an offline solution, you may consider a light-weight third-party program like PDFShaper.

Using PDFShaper to merge PDF files

We’ve already seen how to use PDFShaper to delete individual pages or images from PDF files. PDFShaper can also be used to split pages, as well as merge multiple PDF files into one.

Start PDFShaper and add the PDF files you want to merge.

Arrange the files using the Up or Down arrow toolbar buttons. The PDF files will be merged in the same order you specify here.

In the right-pane, scroll down the list and click Merge

Select the output file name when prompted.

That’s it! The consolidated PDF file is ready and has exactly the same size as the individual PDF files combined.

Using PdfMerge to combine multiple PDF files

PdfMerge, an open-source PDF merger software with bookmark importing and pagination, was written to fill the need for producing large PDF documents from multiple sources in a manual or automated way. To serve this need it meets the following requirements:

  • Allow the merge process to be programmatically driven
  • Allow the creation of bookmark trees by specifying bookmarks to be added
  • Allow the import of bookmarks from the merged documents.
  • Support merging of large documents quickly
  • Allow population of document title fields
  • Supports optional page numbering and footer annotation

To add PDF files to the list, select one or more PDF files and drag and drop them onto the PdfMerge window. Alternately, press the Add Files button.

You can change the order using the up and down buttons.

Command-line Arguments

PdfMerge also supports command-line merge operations using a plain-text or XML command file. Here is the command-line syntax:

pdfmerge <merge_command_file_name> <output_file_name> [/showpdf] [/showgui]
  • merge_command_file_name: Command file in plain text or XML format
  • output_file_name: Name of output PDF file
