Be it a student shuffling assignments around, a professional managing a mountain of reports, or simply someone organizing personal documents, converting DOCX files to PDF always seems to crop up as a never-ending task. But what if there are multiple files you wish to convert? Manual saving of each Word document as a PDF can easily start looking like an endless chore.

Why Mass Convert DOCX to PDF?

Before jumping into methods, let us talk about why one would need to batch convert DOCX files into PDF:

  • Standardized formatting: The structure in which they are viewed remains constant from one device to another, and with all operating systems.
  • Security and protection: Passwords may be applied, and editing and signing may be restricted to PDFs.
  • Professionalism: The look of PDFs is more formal than that of other file formats and is generally accepted for formal documentation.
  • Easy to share and print: PDFs print and share well without regrettable changes in formatting.

PDF is almost the ideal document format. But when dealing with a whole heap of DOCX files, converting them one by one seems like… no. So much more to learn about how to convert multiple DOCX to PDF in one stroke. Now let’s explore the solutions!

Microsoft Word’s Mass Convert DOCX to PDF Feature (Manual Approach)

Microsoft Word has the functionality to save DOC, DOCX and DOCM in PDF format, but the process becomes a bit tedious when trying to convert multiple DOCX to PDF files in a single stroke. This solution becomes relevant when the number of files being converted is not too huge and the conversion is manual.

Steps to Converting DOCX to PDF Manually in Microsoft Word

  1. Open Microsoft Word and load the files you intend to convert.
  2. For each file, go to File > Save As, select PDF and save. 
  3. Repeat for every DOCX file you want to convert. 

Disadvantages

  • Becomes tedious with too many files. 
  • Quite time-consuming. 
  • Might cause formatting discrepancies. 

Though it works, it’s a time-consuming method and doesn’t fit for mass conversion types. But hey, it is free and requires no extra software!

Online DOCX to PDF Converters (Quick but Risky)

If you find yourself needing to mass convert DOCX to PDF but have no time or space to install software, consider online services such as Smallpdf, ILovePDF, and Zamzar. The biggest drawback, however, is the fact that they really limit the number of files you can upload at once for free use. Also, ensure that your connection is stable while doing so.

Steps to follow for using online tools

  1. Drag-and-drop your DOCX files to the online converter.
  2. Select a format or type PDF, and Start Conversion.
  3. Download your PDFs once done.

Disadvantages:

  • Privacy Issue: Uploading sensitive documents in third-party sites can be dangerous. 
  • File Size Limits: Most free converters have restrictions. 
  • Internet Dependency: It needs stable internet connection. 

Although it is easy to use; online tools may not be the first choice for nooks of privacy such as sensitive documents.

PowerShell Script to Batch Convert DOCX to PDF (Advanced Users)

PowerShell scripting allows a user to automate DOCX to PDF conversion. Here is the script:

$word = New-Object -ComObject Word.Application

$word.Visible = $false

$files = Get-ChildItem -Path "C:\Docs" -Filter *.docx

foreach ($file in $files) {

    $doc = $word.Documents.Open($file.FullName)

    $pdfPath = $file.FullName -replace ".docx$", ".pdf"

    $doc.SaveAs([ref]$pdfPath, [ref]17)

    $doc.Close()

}

$word.Quit()

Steps to batch convert DOCX to PDF with Python script

  1. Put the script in the PowerShell window. 
  2. Change the C:\Docs path with your folder location. 
  3. Execute the script to convert all DOCX files to PDF files. 

Disadvantages

  • Requires knowledge of PowerShell. 
  • Works only on the Windows platform. 
  • Any errors in the script could compromise file conversion. 

Why Automation is the Future 

Let us be honest: manual methods and online tools are limited. When you have dozens to hundreds of files to convert, automation is your best bet. The first solution works in this regard, eliminating not just time but also inconsistency and retains quality of all your documents.

Final Thoughts: Which Method Should You Choose?

It is safe to say that acquiring a skill to mass convert DOCX files into PDF could save you hours of tedious work. Quite clearly, the method you choose will depend on your requirements:

  • Fast and automated with the best control: SysTools Batch Converter
  • A small number of files to convert: Microsoft Word is sufficient. 
  • Online tools are good for occasional use, just be mindful of privacy risks. 
  • PowerShell is awesome but more tech-savvy.
