Merge PDF Command Line Windows

Why Use the Command Line for Merging PDFs?

The command line interface offers significant advantages when it comes to automating PDF merging tasks. It's particularly useful when you need to perform the same merging operation on a regular basis or as part of a larger automated workflow. Command-line tools excel in scripting and batch processing, allowing you to merge hundreds or even thousands of PDF files with a single command. This is especially valuable in server-side environments where manual intervention is impractical.

Furthermore, command-line tools can be seamlessly integrated with other tools and applications, expanding your automation possibilities. By incorporating PDF merging into your scripts, you can create customized solutions tailored to your specific needs. Whether you're developing a document management system or automating report generation, command-line tools provide the flexibility and power you need. This flexibility makes it a powerful approach for those with the technical expertise.

Popular Command-Line Tools for Merging PDFs on Windows

Several command-line tools are available for merging PDFs on Windows, each with its own strengths and syntax. Let's explore some of the most popular options.

PDFtk (PDF Toolkit)

PDFtk, or PDF Toolkit, is a widely used command-line tool for manipulating PDFs, including merging. It's available for Windows, offering both command-line and GUI versions. PDFtk is known for its simplicity and ease of use, making it a good choice for basic PDF merging tasks. It's a practical, functional tool.

Basic Syntax & Examples:

• Merging all PDFs in a directory: pdftk.exe *.pdf cat output combined.pdf
• Merging specific files: pdftk.exe input1.pdf input2.pdf cat output combined.pdf
• Merging with absolute paths: \\myserver\c$\path\to\pdftk.exe input1.pdf input2.pdf cat output combined.pdf

PDFtk also supports advanced usage, such as specifying page ranges for merging. This allows you to select specific pages from existing PDFs to include in the merged output, offering even greater control over the process.

Ghostscript

Ghostscript is a powerful interpreter for the PostScript language and PDF. It is more than just a PDF manipulation tool; it is a complete solution for rendering and converting various document formats. Ghostscript, therefore, offers a comprehensive solution with broad support.

Command syntax for merging:

gswin32c.exe -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=output.pdf input1.pdf input2.pdf input3.ps input4.eps input5.pdf

2PDF

2PDF is a command-line tool that can merge PDF files, text files, images, emails, and other file types into a single PDF from the command line interface (CLI). It provides different flags and commands for merging different file types.

Commands & Flags:

• -src: Source files
• -dst: Destination path
• -pdf: PDF Specific flags
• multipage:append: Appends files to the end
• multipage:prepend: Prepends files to the beginning
• combine:"name.pdf": Names the output combined file

Examples:

• Merging PDFs into one multi page document: 2PDF.exe -src "E:\Work\PDF\*.pdf" -dst "C:\Out" -pdf multipage:append combine:"my multipage.pdf"
• Merging multiple text files: 2PDF.exe -src "E:\Work\Word DOCX and RTF files\*.*" -dst "C:\Out" -pdf multipage:append combine:"my multipage.pdf"
• Merging multiple Images: 2PDF.exe -src "E:\Work\Images\*.*" -dst "C:\Out" -pdf multipage:append combine:"my multipage.pdf"

PageMaster

PageMaster is another CLI option for Windows, Linux, and Mac. It allows for more advanced merging, including page range selection and interweaving documents.

Basic command syntax:

pagemaster (-m or --merge)<input1.PDF>,<pagelist1>,<pagelist2> <input2.PDF>,<pagelist3> <PDF folder> <input3.PDF> etc.

Merging example:

pagemaster --m in1.pdf in2.pdf MyPDFs -o Output/merged.pdf

• Selecting page ranges: pagemaster -m in.pdf,1-5 MyPDFs,1-5
• Odd/Even page merging: pagemaster -m in1.pdf,e in2.pdf,o -o out.pdf
• Interweaving documents using '--splice' option.

Win2PDF Pro

Win2PDF Pro is designed for appending and prepending PDF files through the command line interface. It can handle both local files and web addresses.

• win2pdfd.exe append "file1" "file2" "mergedfile"
• For prepending, swap file1 and file2 parameters.
• Local Files, Web Addresses, or combination of the two can be used.

Alternatives to Command Line

Online PDF Merging Tools

Numerous reputable online tools, such as Adobe Acrobat Online, iLovePDF, and Smallpdf, allow you to merge PDFs directly in your web browser. These tools are convenient and easy to use, but it's essential to exercise caution when uploading sensitive documents. Always review the privacy policies of these services to understand how your data is handled. Consider using a tool that prioritizes your privacy and data security.

Desktop Applications

Several desktop applications, such as PDF Merger & Splitter and PDF Arranger, offer a GUI-based approach to merging PDFs.
