How to set different margin settings in HTML when converting to PDF using C# in ASP.NET MVC?

Syncfusion® HTML to PDF for .NET is used to convert webpages, SVG, MHTML, and HTML to PDF. Using this library, you can set different page margins in HTML when converting to PDF document.

Steps to set different margin settings in HTML to PDF conversion programmatically:

1. Create a new ASP.NET MVC application project.
2. Install the Syncfusion.HtmlToPdfConverter.AspNet.Mvc5 NuGet package as a reference to your .NET Framework applications from NuGet.org.

3. A default controller with name HomeController.cs gets added on creation of ASP.NET MVC project. Include the following namespaces in that HomeController.cs file.

C#

using Syncfusion.Pdf;
using Syncfusion.HtmlConverter;
using System.Drawing;

4. A default action method named Index will be presented in HomeController.cs. Right-click this action method and select Go To View, where you will be directed to its associated view page Index.cshtml.
5. Add a new button in the Index.cshtml as follows.

   @using (Html.BeginForm("ConvertHtmlToPdf", "Home", FormMethod.Post))
   {
       <input type="submit" value="Convert" />
   }
   

6. Add a new action method named ConvertHtmlToPdf in HomeController.cs and include the following code snippet to set different margin settings in the conversion of HTML to PDF file and download it.

C#

//Input HTML URL to convert 
string url = Server.MapPath("~/Data/TableHTML.htm");
 
//Initialize HTML to PDF converter
HtmlToPdfConverter htmlConverter = new HtmlToPdfConverter();
 
//Initialize Blink converter settings 
BlinkConverterSettings settings = new BlinkConverterSettings();
 
//Enable JavaScript 
settings.EnableJavaScript = true;
settings.MediaType = MediaType.Print;
 
//Disable split images and text lines
settings.SplitImages = false;
settings.SplitTextLines = false;
 
//Set blink view port size
settings.ViewPortSize = new Size(1200, 0);
 
//Set PDF page margin 
settings.Margin = new Syncfusion.Pdf.Graphics.PdfMargins { Top = 40, Left = 30, Right = 40, Bottom = 50 };
htmlConverter.ConverterSettings = settings;
 
//Convert URL to PDF document
PdfDocument document = htmlConverter.Convert(url);
 
//Save and close the PDF document
document.Save("Output.pdf", HttpContext.ApplicationInstance.Response, HttpReadType.Save);
document.Close(true);
return null;
