By integrating a reliable PDF editing solution like IronPDF into .NET applications, developers can enhance the user experience, streamline document workflows, and provide a seamless editing experience for PDF files.
This article will guide you through the process of creating a .NET PDF editor using IronPDF, enabling you to harness the power of PDF editing in your application development projects.
To create a .NET PDF editor application using IronPDF, you need to set up the development environment and configure your project in Visual Studio. Follow the steps below:
Start by installing the IronPDF library, which provides the necessary tools for working with PDF files in .NET applications. You can download and install the library by following the instructions provided in the IronPDF Installation Guide.
Open Visual Studio and create a new project using the .NET Framework or .NET Core, depending on your requirements. Choose the appropriate project template based on the type of application you want to develop, such as a Windows Forms application or a .NET Web Application.
Once the project is created, add references to the IronPDF Library in your project. You can do this by right-clicking on the "References" folder in your project within Visual Studio, selecting "Add Reference," and browsing for the IronPDF assembly.
In the code file where you want to use IronPDF, import the IronPDF namespace to access the library's classes and methods. Add the following line at the beginning of your file:
using IronPdf;
using IronPdf;
Imports IronPdf
Configure IronPDF to integrate seamlessly into your project. This step involves setting up the necessary configurations and initializing IronPDF in your application.
Refer to the IronPDF Documentation or the articles mentioned above for detailed instructions on configuring IronPDF for your specific project type.
By following these steps, you will have successfully set up the development environment and configured your project in Visual Studio to work with IronPDF, enabling you to create a .NET PDF editor application that can modify PDF documents, edit PDF pages, add annotations, and more.
To create a basic PDF editor application in C#, start by creating a new project in Visual Studio. Choose the appropriate project template based on the type of application you want to develop, such as a Windows Forms application or a .NET Web Application. You can refer to the provided articles for detailed instructions and examples on creating a C# project for PDF editing.
After creating the project, add the necessary references to enable PDF editing functionality. In the case of IronPDF, you need to add references to the IronPDF library. This can be done by right-clicking on the References folder in your project within Visual Studio, selecting "Add Reference," and browsing for the IronPDF assembly. The specific steps may vary based on your project type and version of Visual Studio.
Once the references are added, you need to initialize IronPDF in your application to start working with PDF documents. This involves configuring IronPDF and setting up any required parameters. The IronPDF Documentation and the provided articles offer guidance on how to initialize IronPDF in your application.
Open Visual Studio, preferably Visual Studio 2019, or any other version you prefer.

To work with IronPDF and generate PDF documents, you need to install the IronPDF NuGet package. Here's how:
Go to the "Project" menu in Visual Studio and select "Manage NuGet Packages".
NuGet Package Manager
In the NuGet Package Manager, switch to the "Browse" tab and search for "IronPDF".
Browse for the IronPDF package in NuGet Package Manager UI
Now, let's design the Windows Forms where users can enter text and save it as a PDF document:
Open the Form1 design view in Visual Studio.
Form Design View
On the left side of the window, locate the toolbar and find the label control. Drag and drop it onto the form design area.
Form Design
RichTextBox
control and three buttons onto the form. The buttons will be used for saving the text as a PDF, clearing the text, and closing the window, respectively.Next, let's write the necessary code for creating PDF documents when the user clicks the "Save" button:
private void Save_Click(object sender, EventArgs e)
{
// Open a dialog to select the folder to save the file
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.InitialDirectory = @"D:\";
saveFileDialog1.Title = "Save Pdf File";
saveFileDialog1.DefaultExt = "pdf";
saveFileDialog1.Filter = "PDF files (*.pdf)|*.pdf|All files (*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
// Check if the user clicked OK
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
string filename = saveFileDialog1.FileName;
// Create PDF document from the text in the RichTextBox
var renderer = new ChromePdfRenderer();
renderer.RenderHtmlAsPdf(PdfText.Text).SaveAs(filename);
// Show a message box to confirm the file has been saved
MessageBox.Show("File Saved Successfully!");
}
}
private void Save_Click(object sender, EventArgs e)
{
// Open a dialog to select the folder to save the file
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.InitialDirectory = @"D:\";
saveFileDialog1.Title = "Save Pdf File";
saveFileDialog1.DefaultExt = "pdf";
saveFileDialog1.Filter = "PDF files (*.pdf)|*.pdf|All files (*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
// Check if the user clicked OK
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
string filename = saveFileDialog1.FileName;
// Create PDF document from the text in the RichTextBox
var renderer = new ChromePdfRenderer();
renderer.RenderHtmlAsPdf(PdfText.Text).SaveAs(filename);
// Show a message box to confirm the file has been saved
MessageBox.Show("File Saved Successfully!");
}
}
Private Sub Save_Click(ByVal sender As Object, ByVal e As EventArgs)
' Open a dialog to select the folder to save the file
Dim saveFileDialog1 As New SaveFileDialog()
saveFileDialog1.InitialDirectory = "D:\"
saveFileDialog1.Title = "Save Pdf File"
saveFileDialog1.DefaultExt = "pdf"
saveFileDialog1.Filter = "PDF files (*.pdf)|*.pdf|All files (*.*)|*.*"
saveFileDialog1.FilterIndex = 2
saveFileDialog1.RestoreDirectory = True
' Check if the user clicked OK
If saveFileDialog1.ShowDialog() = DialogResult.OK Then
Dim filename As String = saveFileDialog1.FileName
' Create PDF document from the text in the RichTextBox
Dim renderer = New ChromePdfRenderer()
renderer.RenderHtmlAsPdf(PdfText.Text).SaveAs(filename)
' Show a message box to confirm the file has been saved
MessageBox.Show("File Saved Successfully!")
End If
End Sub
To handle the functionality of the "Clear" and "Close" buttons:
private void Clear_Click(object sender, EventArgs e)
{
// Clear the text in the RichTextBox
PdfText.Text = "";
}
private void Clear_Click(object sender, EventArgs e)
{
// Clear the text in the RichTextBox
PdfText.Text = "";
}
Private Sub Clear_Click(ByVal sender As Object, ByVal e As EventArgs)
' Clear the text in the RichTextBox
PdfText.Text = ""
End Sub
private void Close_Click(object sender, EventArgs e)
{
// Dispose of the form, essentially closing it
this.Dispose();
}
private void Close_Click(object sender, EventArgs e)
{
// Dispose of the form, essentially closing it
this.Dispose();
}
Private Sub Close_Click(ByVal sender As Object, ByVal e As EventArgs)
' Dispose of the form, essentially closing it
Me.Dispose()
End Sub
