Converted word to pdf the images are blur in pdf

Hi,
I have using ASPOSE.Net Words to convert my word file into PDF. After converting the images are blur.
In the attached files “Generate_Using_ASPOSE.pdf” generate using ASPOSE and “SaveAs_PDF_Using_WORD.pdf” save as PDF using WORD.
Please suggest the fix for this.SaveAs_PDF_Using_WORD-Copy.pdf (31.7 KB)

Hi alexey.noskov,
Thanks for your quick reply.
I’m attaching the document file. But I just want inform you I’m generating the PDF file using a dynamic word document having some merge fields and replace the image dynamically also.Bonafide Certificate Template (1)-Copy.docx (34.0 KB)

@wefivesoft Thank you for additional information. You can set the following option to improve quality of the image:

Document doc = new Document(@"C:\Temp\in.docx");
PdfSaveOptions opt = new PdfSaveOptions();
opt.JpegQuality = 100;
opt.UseAntiAliasing = true;
opt.DownsampleOptions.DownsampleImages = false;
doc.Save(@"C:\Temp\out.pdf", opt);

But still the quality of the image in the source document is poor and the result cannot be better than the source image quality.

I have tried with your suggestion but no luck. It’s showing still blur image. File attached.
The code I have used as per your suggestion:

public MemoryStream ConvertWordToPDF(MemoryStream stream)
{
	MemoryStream pdfStream = new MemoryStream();
	// Create a new memory stream.
	MemoryStream outStream = new MemoryStream();
	try
	{
		licenseAW.SetLicense(@"Aspose.Words.NET.lic");
		AW.Document doc = new AW.Document(stream);

		AW.Saving.PdfSaveOptions opt = new();
		opt.SaveFormat = Aspose.Words.SaveFormat.Pdf;
		opt.JpegQuality = 100;
		opt.UseAntiAliasing = true;
		opt.DownsampleOptions.DownsampleImages = false;

		// Save the document to stream.
		doc.Save(outStream, opt);

		// Convert the document to byte form.
		byte[] docBytes = outStream.ToArray();

		// The bytes are now ready to be stored/transmitted.
		// Now reverse the steps to load the bytes back into a document object.
		pdfStream = new MemoryStream(docBytes);

		//To see the pdf output
		string base64String = Convert.ToBase64String(docBytes, 0, docBytes.Length);
	}
	catch (Exception ex)
	{
		_logger.LogError(ex, "ConvertWordToPDF");

	}
	finally
	{
		stream.Close();
		outStream.Close();
	}
	return pdfStream;
}

@wefivesoft As I can see the document you have attached was produced or postprocessed by MS Office 365. If I convert your document to PDF using the code I have provided the image looks better. Please see the attached document: out.pdf (64.6 KB)
