Aspose.PDF - PDF to DOCX conversion issues

When using the Aspose.PDF free converter at https://products.aspose.app/pdf/conversion our PDF converts to DOCX with a nearly identical layout. However, when we attempt to convert using C# on .NET Core in Debian Linux the conversion is missing some of the signature lines and one page is jumbled. Can you help me understand what may be different about the Aspose online conversion tool and our .NET installation to help us achieve similar results?

We’ve tried using both versions of the code samples at https://docs.aspose.com/pdf/java/convert-pdf-to-docx/. Our latest C# implementation looks like:

public static void PDFToWord(string sourceUri, string destUri)
    if (File.Exists(@sourceUri))
        var pdfDoc = new Aspose.Pdf.Document(sourceUri);

        Aspose.Pdf.DocSaveOptions saveOptions = new Aspose.Pdf.DocSaveOptions();
        saveOptions.Format = Aspose.Pdf.DocSaveOptions.DocFormat.DocX;
        saveOptions.Mode = Aspose.Pdf.DocSaveOptions.RecognitionMode.Flow;
        saveOptions.RecognizeBullets = true;

        pdfDoc.Save(Path.GetFullPath(destUri), saveOptions);
        Console.Error.WriteLine("Unable to find file");
        Environment.ExitCode = 1;

I can reproduce that the signatures of Amy Winters are missing on Page 2 but can you please share a snapshot of the jumbled page so that we may proceed further with investigation on our end.

These previews are in Microsoft Word for mac version 16.43. Below I’ve included screenshots of each page as we see them when comparing the Aspose.app conversion (on the left in each screenshot) to the conversion generated locally by Aspose.PDF on .NET Core 3.1 (on the right in each screenshot).

Page 1: page-1-comparison.png (69.0 KB)

  • Missing two signature lines.

Page 2: page-2-comparison.png (71.0 KB)

  • Missing 4 signature lines.
  • Missing Amy Winters signature

Page 3: page-3-comparison.png (90.1 KB)

  • Missing the signature line under Paul Schilpp
  • The text and signature lines in the second and third columns are jumbled.

Page 4: (No screenshot)

  • Renders as expected.
