How to Convert Views to PDFs in ASP.NET Core MVC
A View is a component in the ASP.NET framework used for generating HTML markup in web applications. It is a part of the Model-View-Controller (MVC) pattern, commonly used in ASP.NET MVC and ASP.NET Core MVC applications. Views are responsible for presenting data to the user by rendering HTML content dynamically.
ASP.NET Core Web App MVC (Model-View-Controller) is a web application provided by Microsoft for building web applications using ASP.NET Core.
- Model: The Model represents data and business logic, manages data interactions, and communicates with data sources.
- View: The View presents the user interface, focuses on displaying data, and renders information to the user.
- Controller: The Controller handles user input, responds to requests, communicates with the Model, and orchestrates interactions between the Model and the View.
IronPDF simplifies the process of creating PDF files from Views within an ASP.NET Core MVC project. This makes PDF generation easy and direct in ASP.NET Core MVC.
How to Convert Views to PDFs in ASP.NET Core MVC
IronPDF Extension Package
The IronPdf.Extensions.Mvc.Core package is an extension of the main IronPdf package. Both the IronPdf.Extensions.Mvc.Core and IronPdf packages are needed to render Views to PDF documents in an ASP.NET Core MVC.
Install-Package IronPdf.Extensions.Mvc.Core
Install with NuGet
Install-Package IronPdf.Extensions.Mvc.Core

Render Views to PDFs
You'll need an ASP.NET Core Web App (Model-View-Controller) project to convert Views into PDF files.
Add a Model Class
- Navigate to the "Models" folder
- Create a new C# class file named "Person." This class will act as a model to represent individual data. Use the following code snippet:
:path=/static-assets/pdf/content-code-examples/how-to/cshtml-to-pdf-mvc-core-model.csnamespace ViewToPdfMVCCoreSample.Models
{
public class Person
{
public int Id { get; set; }
public string Name { get; set; }
public string Title { get; set; }
public string Description { get; set; }
}
}Namespace ViewToPdfMVCCoreSample.Models
Public Class Person
Public Property Id() As Integer
Public Property Name() As String
Public Property Title() As String
Public Property Description() As String
End Class
End NamespaceVB C#
Edit the Controller
Navigate to the "Controllers" folder and open the "HomeController" file. We are going to make changes only to the HomeController and add the "Persons" action. Please refer to the code below for guidance:
The code below first instantiates the ChromePdfRenderer class, passing an IRazorViewRenderer, the path to our "Persons.cshtml," and the List that contains the required data to the RenderRazorViewToPdf method. Users can utilize RenderingOptions to access a range of features, such as adding custom text, including HTML headers and footers in the resulting PDF, defining custom margins, and applying page numbers.
Please note
The PDF document can be viewed in the browser using the following code:
File(pdf.BinaryData, "application/pdf"). However, downloading the PDF after viewing it in the browser results in a damaged PDF document.using IronPdf.Extensions.Mvc.Core;

After using the RenderRazorToPdf method, you'll receive a PdfDocument object that's open to further enhancements and modifications. You have the flexibility to convert the PDF to PDFA or PDFUA formats, add your digital signature to the generated PDF, or merge and split PDF documents as needed. Additionally, the library allows you to rotate pages, insert annotations or bookmarks, and imprint unique watermarks onto your PDF files.
Add a View
- Right-click on the newly added Person action and select "Add View."
- Choose "Razor View" for the new Scaffolded item.
- Select the "List" template and the "Person" model class.
This will create a .cshtml file named "Persons."
- Navigate to the "Views" folder -> "Home" folder -> "Persons.cshtml" file.
To add a button that invokes the "Persons" action, use the code below:
@using (Html.BeginForm("Persons", "Home", FormMethod.Post))
{
<input type="submit" value="Print Person" />
}@using (Html.BeginForm("Persons", "Home", FormMethod.Post))
{
<input type="submit" value="Print Person" />
}HTML
Add a Section to the Top Navigation Bar
- In the same "Views" folder navigate to the "Shared" folder -> _Layout.cshtml. Place the "Person" navigation item after "Home".
Make sure the value for the asp-action attribute matches exactly with our file name, which in this case is "Persons".
