The Syncfusion HTML to PDF converter is a .NET library used to convert HTML or web pages to PDF document in ASP.NET MVC application.

Steps to convert HTML to PDF document in ASP.NET MVC

@{Html.BeginForm("ExportToPDF", "Home", FormMethod.Post);
    {
        <div>
            <input type="submit" value="Convert PDF" style="width:150px;height:27px" />
        </div>
    }
    Html.EndForm();

Step 6: Add a new action method named ExportToPDF in HomeController.cs and include the below code example to convert HTML to PDF document using Convert method in HtmlToPdfConverter class. The HTML content will be scaled based on the given ViewPortSize property of BlinkConverterSettings class.

//Set Blink viewport size.
blinkConverterSettings.ViewPortSize = new System.Drawing.Size(1280, 0);
//Assign Blink converter settings to HTML converter.
htmlConverter.ConverterSettings = blinkConverterSettings;
//Convert URL to PDF document.
PdfDocument document = htmlConverter.Convert("https://www.syncfusion.com");
//Create memory stream.
MemoryStream stream = new MemoryStream();
//Save the document to memory stream.
document.Save(stream);
return File(stream.ToArray(), System.Net.Mime.MediaTypeNames.Application.Pdf, "HTML-to-PDF.pdf");
