docx isn't supported when Word isn't installed

I just wanted to convert (or combine) multiple docx files in Acrobat and was baffled when it showed me, docx wasn’t supported.

In the convert tool, the open dialogue won’t even show docx as supported file type.

Every support and help article I’ve found reads as if Word is a dependency for this to work? Why?
There is nowhere advertised that I need Word for this tool to work, one of the primary reasons to use Acrobat. I don’t own Word and I don’t want to own Word.

It gets more absurd from there when I try thinking about a reason for that.
The first that comes to mind with proprietary formats is licensing but other programs can do with no problem and Adobe themselves offer the conversion online.
Yes, I could use the online tools but why should I? I pay for Acrobat and even inside of Acrobat, there is clear as day stated “choose one of the formats: docx, xlsx, txt” but then docx is not supported. What?

If that’s a technical “limitation” because Word is used for that conversion, this is a major red flag for Adobe and that they can’t even come up with their own way of converting docx when others clearly can WITHOUT Word installed.

So, is there a way to convert docx to pdf without Word installed or is this a huge problem in Adobe’s side?

    Acrobat requires MS Word to be installed if you want to convert files locally. The only way around this is to use the online service.

    Hi ​@athletic_fact6385 ,

     

    What program(s) are you currently using to view and edit Microsoft Word documents?

     

    Microsoft Word doesn't have to be installed to fulfill your needs with Adobe Acrobat Pro DC. However, you do need a program that can view, read, or modify .docx files. 

     

    Just keep in mind... You need software that can read MS Word files at the very least. It's important to consider how you can view .docx files.

     

    Fortunately, there are many open-source alternatives to MS Word that you can download and install for free, and they will work perfectly!

     

    So, before you manually trigger the conversion tool or the combine files tool, it's essential to establish a default .docx handler. This will enable Adobe Acrobat to detect the program set as the default app and acknowledge it as the source application that created those .docx files.

     

    In other words, whatever software you are using, make sure to set it as your default .docx handler at the operating system level. If you don't, Acrobat won't recognize any application that can handle .docx files when you attempt to convert or combine them with Acrobat.


    If you still don't want to do that (or use the Online Conversion Tool as correctly answered by ​@Karl Heinz Kremer ), you can explore other methods for converting Word to PDF.

     

    For instance, you can use the Built-in Virtual Printer, selecting "Microsoft Print to PDF" or "Adobe PDF" from the print menu of any application (to include, web browsers that support PDF viewing) to save a document as a PDF, as per official Microsoft Support guidance.

    Can you explain me, why I’m able to save to docx but not read them?
    This still doesn’t make sense to me.

    As for your question. I use OnlyOffice at the moment. Handles docx without any problem and is the default software for docx files. It also can export to pdf but not merge and not multiple files at once. That’s where Acrobat should come into play if it would work as expected.
    Where can I set the handler in Acrobat?

     

    Still, I don’t see why there are any dependencies and why Acrobat don’t ship with conversion tools included if it is advertised as a feature of Acrobat. It’s like advertising certain codecs in Premiere but to be able to use it, I have to buy them first… should at least be mentioned somewhere.

     

    Thanks for the insight btw.

    Acrobat installs an extension in MS Office applications to assist in the conversion to PDF: https://helpx.adobe.com/acrobat/using/creating-pdfs-pdfmaker-windows.html

     

    iIf you have a different application to process Word documents, that PDFMaker extension will of course. It get installed and therefore will not allow Acrobat to control that application.

    Frankly, the marketing department should mention that unmistakable (both on the website and the program itself) because no other local tool I used before had any restrictions like that. If it is advertised as part of Acrobat it should be part of Acrobat instead of using other software for that purpose that is not included.
    You could argue, Acrobat isn’t doing the conversion, Word is. So advertising docx to pdf conversion as part of Acrobat is just blatantly false.

    Why even have a local tool at all when the answer is “use the online tool”? (even as a workaround).
    Using the online service is no real solution for several reasons.

    I’m honestly stunned that this is a problem in the first place and it gets even more confusing when exporting a pdf to docx is still possible without Word.

    ​@ath mis 912005 From Google’s AI overview when looking up this topic (sounds trustworthy):

    ---------------------------------------------------------------------

    Adobe Acrobat requires Microsoft Word to be installed on a desktop machine to convert .docx files to PDF because it uses Word's own rendering engine to interpret the document's structure, fonts, and formatting accurately. 

    When using Acrobat to convert a Word document, Acrobat effectively opens a hidden instance of MS Word to perform the conversion through a specialized plugin called PDFMaker.

    --------------------------------------------------------------------------------

    ...this is a major red flag for Adobe and that they can’t even come up with their own way of converting docx when others clearly can WITHOUT Word installed.

    ...because no other local tool I used before had any restrictions like that.

     

    Just to make sure: Do you mean that you actually did use local tools that convert .docx files to PDF before, and they didn’t require Word to be installed? In this case, why do you need Acrobat?
