Aspose.Words does not Mimic MS Word for Document Structure Tags using .NET | Big Size PDF

Hi,

When converting a word document using Aspose with ‘ExportDocumentStructure’ to true, I noticed the output file is 20 times larger than the pdf created using MS Word under the same setting.

Code:
Document doc = new Document(@“test.docx”);
var saveOption = new PdfSaveOptions();
saveOption.ExportDocumentStructure = true;
saveOption.Compliance = Aspose.Words.Saving.PdfCompliance.PdfA1b;
doc.Save(@“AsposeOutput.pdf”, saveOption);

The output pdf files from Aspose vs. Word is 7100KB vs. 379KB.

I’ve attached the .docx file and the two pdf output files for your reference. Could you please have a look into this?

Thanks

Hi,

May I have some updates on the status of this ticket?

In my most recent tests, when having ExportDocumentStructure = true, the Pdf1Ab output is still 20x larger than the Word PdfA1b output, and Pdf15/17 output is 7 times larger than the Word ‘save as’ Pdf17 output.

The ExportDocumentStructure is becoming increasingly important as regulators in more regions are enforcing the accessibility of the PDF. If Aspose cannot produce a reasonable size compared to the Word PDF with this option, it could be a blocking point.

I’ve attached the latest example outputs for your reference.
