Tagged PDF disabled after docx to pdf conversion



When I convert docx document to pdf using this code snippet:

Aspose.Words.Document docx = new Aspose.Words.Document(@“C:\Testdoc.docx”);
var saveOptions = new Aspose.Words.Saving.PdfSaveOptions
{ SaveFormat = Aspose.Words.SaveFormat.Pdf };
docx.Save(@“C:\Testdoc.pdf”, saveOptions);

The result pdf has “Tagged PDF: No” (when looking at generated PDF properties in Aspose.
When doing the same conversion in Word it is possible to define if tagged pdf should be enabled or not. By default it is enabled.
Tagged PDF are supported by PDF format since version 1.4. Aspose generates version 1.5 so it should be possible.

Question is what API setting should be provided (maybe to SaveOptions?) to make this Tagged PDF enabled?




Please use the PdfSaveOptions.ExportDocumentStructure property as shown below to get the “Tagged PDF” output.

Document doc = new Document(MyDir + "input.docx");
PdfSaveOptions pdfSaveOptions = new PdfSaveOptions();
pdfSaveOptions.ExportDocumentStructure = true;
doc.Save(MyDir + "19.5.pdf", pdfSaveOptions);


Hi @tahir.manzoor,

Thanks, your suggestion works for PDF conversion. However, if I have to merge a couple of Tagged PDFs (after the conversion) using the following code:

void MergePdfs(List streams, Stream outputStream)
var output = new Aspose.Pdf.Document();

foreach (var stream in streams)
    var doc = new Aspose.Pdf.Document(stream);




The result is not a tagged PDF. Do you have a solution for this? I had a look at the Aspose.PDF.Saving.SaveOptions class, but it seems of no help here.

Thanks in advance!



To ensure a timely and accurate response, please attach the following resources here for testing:

  • Your input Word and PDF documents.
  • Please create a standalone console application ( source code without compilation errors ) that helps us to reproduce your problem on our end and attach it here for testing.

As soon as you get these pieces of information ready, we will start investigation into your issue and provide you more information. Thanks for your cooperation.

PS: To attach these resources, please zip and upload them.



Attached console app works on trial, but the outcome is the same when I set the license as well.

The app takes one file - testDocument.docx. It’s a simple Word document. Please adjust the path to the document in source code of attached app.

The app produces 3 files:

  • taggedPDF1.pdf - tagged PDF: Yes
  • taggedPDF2.pdf - tagged PDF: Yes
  • merged.pdf - tagged PDF: No

Our expectation was that if we open and close PDFs that are already tagged, the outcome would also be tagged. Is there any way to achieve that?

Also, we would like to be able to achieve merged Tagged PDF for content that is only partially tagged - e.g. 3 PDFs that are tagged, and one that is not. Is this possible?



We could not find any attached project or sample file with your post. Would you please make sure to upload them using upload button in post editor.

You’re right, the file was too large to upload it here. I put it on Dropbox https://www.dropbox.com/s/vr4vl9r8seepvc9/AsposeTaggedPDFTestConsoleApp.zip?dl=0
