Hi Jean,

Thank you for your interest in Syncfusion products.

1.    Could you please check if you have Internet Explorer version 9 installed in your machine? HtmlConverter makes use of MSHTML (IE rendering engine) to convert the webpage to image. With IE 9 there is a known issue that it generates only raster image which when drawn in PDF appears blurry. You can get more information on this from the following link:


As explained, to solve this, the key FEATURE_IVIEWOBJECTDRAW_DMLT9_WITH_GDI should be updated in the registry. Please run the utility placed in the following location to perform the above changes automatically.

Legacy Drawing.zip

Please try this and let me know if you have any questions.

Do you enter a right code?Here is a demo code:
namespace RE__Test
public partial class Form1 : Form
public Form1()

private void button1_Click(object sender, EventArgs e)

RasterEdgeImaging PDF = new RasterEdgeImaging();
public void ConvertPdftoHtml();
PDFInputFile = (@"C:/1.pdf");
PDFPageNumber = "1";
HTMLOutputFile = OutputFormat.html;
PDF.Save("OutputFormat.html", SaveFormat.Html);

Hi Abigail,

Thank you for your update.


The above discussion was related to converting Html to Pdf using Syncfusion components.

Syncfusion HtmlConverter makes use of MSHTML (IE rendering engine) to convert the webpage to image.

So we have to update the registry.


Please let us know if you have any concern.

Hi Abigali,

Currently we don’t have support for HTML to PDF conversion in Xamarin platform, we have already logged the feature request in our database.
We will update you once the feature has been implemented.

Please let us know if you need further assistance.

With Regards,
