Edition Windows 10 Enterprise
Version 21H2
OS build 19044.2486
Experience Windows Feature Experience Pack 120.2212.4190.0

Im attaching the sample files FYR and also PFB code with which we are trying. Please let me know of any questions.

Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(dataDir + "input PDF.pdf");

Aspose.Pdf.PptxSaveOptions pptx_save = new Aspose.Pdf.PptxSaveOptions();
pdfDocument.Save(dataDir + "OutPut PPT.pptx", pptx_save);

We have also tried with different PptxSaveOptions options but no luck

Aspose.Pdf.PptxSaveOptions pptx_save = new Aspose.Pdf.PptxSaveOptions
{
    SeparateImages = true,
};

Aspose.PDF does not support conversion docx to images, but it can unload attachments.
We have prepared a code snippet with comments to solve the problem:

var pdfDocument = new Aspose.Pdf.Document(dataDir + "56773.pdf");
var extractedFiles = new List<string>();
//Extract embedded files
var extractor = new Aspose.Pdf.Facades.PdfExtractor(pdfDocument);
extractor.ExtractAttachment();
foreach (var attachedFile in extractor.GetAttachmentInfo())
{
    var attachName = dataDir + "56773_" + attachedFile.Name;
    extractedFiles.Add(attachName);
    using (var fs = new FileStream(attachName, FileMode.Create))
    {
        attachedFile.StreamContents.CopyTo(fs);
    }
}
var extractedFilesAsPdf = new List<string>();
//Convert to Images by Aspose.Words
foreach (var attachName in extractedFiles)
{
    if (attachName.EndsWith(".doc") || attachName.EndsWith(".docx"))
    {
        var attachConvertedName = attachName.Remove(attachName.IndexOf(Path.GetExtension(attachName))) + ".pdf";
        extractedFilesAsPdf.Add(attachConvertedName);
        var doc = new Aspose.Words.Document(attachName);
        doc.Save(attachConvertedName);
    }
}
//Add pages
foreach (var attachName in extractedFilesAsPdf)
{
    using (var attachDoc = new Aspose.Pdf.Document(attachName))
    {
        pdfDocument.Pages.Add(attachDoc.Pages);
    }
}
//Convert
var pptx_save = new Aspose.Pdf.PptxSaveOptions();
pdfDocument.Save(dataDir + "56773.pptx", pptx_save);

It uses combination of Aspose.Pdf and Aspose.Words.

We have tried this sample and as we can see the word document attachment is unloaded from the pdf and its contents are being added in output PPT.

However, our need is to have output PPT containing the embedded files as attachments. The attachments can be any from pdf, ppt, excel, word document.

Could you please provide the code snippet to achieve this?

Thanks.
