Actualizado:julio 28, 2025

.NET MAUI is the next generation of .NET that enables developers to build cross-platform Desktop, Web, and Mobile Apps, including Xamarin.Forms, with a single codebase. With .NET MAUI, you can write your app once and deploy it to multiple platforms, including Windows, macOS, iOS, Android, and tvOS with the same project name. .NET MAUI also enables you to take advantage of the latest UI capabilities on each platform, such as dark mode and touch support on macOS, or speech recognition on Windows 10.

This article will explain how to use IronPDF in the .NET MAUI app to create PDF documents with many benefits.

You can now start using IronPDF in your MAUI project.

Step 2: Setup Frontend Design in .NET MAUI

Firstly, create a layout for the three functionalities of IronPDF.

URL to PDF Layout

For the URL to PDF layout, create a label with the text "Enter URL to Convert PDF" using a .NET MAUI label control. After that, apply a horizontal stack layout for arranging the Entry control and the button horizontally. Then put a line after the controls to divide the next section of controls.

<Label
    Text="Enter URL to Convert PDF"
    SemanticProperties.HeadingLevel="Level1"
    FontSize="18"
    HorizontalOptions="Center" 
/>
<HorizontalStackLayout
    HorizontalOptions="Center">
    <Border Stroke="White"
            StrokeThickness="2"
            StrokeShape="RoundRectangle 5,5,5,5"
            HorizontalOptions="Center">
        <Entry
            x:Name="URL"
            HeightRequest="50"
            WidthRequest="300" 
            HorizontalOptions="Center"
        />
    </Border>

    <Button
        x:Name="urlPDF"
        Text="Convert URL to PDF"
        Margin="30,0,0,0"
        Clicked="UrlToPdf"
        HorizontalOptions="Center" />
</HorizontalStackLayout>

<Line Stroke="White" X2="1500" />

<Label
    Text="Enter URL to Convert PDF"
    SemanticProperties.HeadingLevel="Level1"
    FontSize="18"
    HorizontalOptions="Center" 
/>
<HorizontalStackLayout
    HorizontalOptions="Center">
    <Border Stroke="White"
            StrokeThickness="2"
            StrokeShape="RoundRectangle 5,5,5,5"
            HorizontalOptions="Center">
        <Entry
            x:Name="URL"
            HeightRequest="50"
            WidthRequest="300" 
            HorizontalOptions="Center"
        />
    </Border>

    <Button
        x:Name="urlPDF"
        Text="Convert URL to PDF"
        Margin="30,0,0,0"
        Clicked="UrlToPdf"
        HorizontalOptions="Center" />
</HorizontalStackLayout>

<Line Stroke="White" X2="1500" />

HTML to PDF Layout

For the layout of the HTML to PDF section, create an Editor control and a button. The Editor control will be used for accepting a string of HTML content from the user. Additionally, add a line as a divider.

<Label
    Text="Enter HTML to Convert to PDF"
    SemanticProperties.HeadingLevel="Level2"
    FontSize="18"
    HorizontalOptions="Center" />
<Border 
    Stroke="White"
    StrokeThickness="2"
    StrokeShape="RoundRectangle 5,5,5,5"
    HorizontalOptions="Center">

    <Editor
        x:Name="HTML"
        HeightRequest="200"
        WidthRequest="300" 
        HorizontalOptions="Center"
    />

</Border>

<Button
    x:Name="htmlPDF"
    Text="Convert HTML to PDF"
    Clicked="HtmlToPdf"
    HorizontalOptions="Center" />

<Line Stroke="White" X2="1500" />

<Label
    Text="Enter HTML to Convert to PDF"
    SemanticProperties.HeadingLevel="Level2"
    FontSize="18"
    HorizontalOptions="Center" />
<Border 
    Stroke="White"
    StrokeThickness="2"
    StrokeShape="RoundRectangle 5,5,5,5"
    HorizontalOptions="Center">

    <Editor
        x:Name="HTML"
        HeightRequest="200"
        WidthRequest="300" 
        HorizontalOptions="Center"
    />

</Border>

<Button
    x:Name="htmlPDF"
    Text="Convert HTML to PDF"
    Clicked="HtmlToPdf"
    HorizontalOptions="Center" />

<Line Stroke="White" X2="1500" />

XML

HTML File to PDF Layout

For the HTML files to PDF, add only one button. That button will help to convert an HTML file to a PDF document using IronPDF.

<Label
    Text="Convert HTML file to PDF"
    SemanticProperties.HeadingLevel="Level2"
    FontSize="18"
    HorizontalOptions="Center" />

<Button
    x:Name="htmlFilePDF"
    Text="Convert HTML file to PDF"
    Clicked="FileToPdf"
    HorizontalOptions="Center" />

<Label
    Text="Convert HTML file to PDF"
    SemanticProperties.HeadingLevel="Level2"
    FontSize="18"
    HorizontalOptions="Center" />

<Button
    x:Name="htmlFilePDF"
    Text="Convert HTML file to PDF"
    Clicked="FileToPdf"
    HorizontalOptions="Center" />

Step 3: Code for Save and View PDF file

.NET MAUI doesn't have any pre-built function to save files in local storage. So, it is necessary to write the code ourselves. For creating the save and view functionality, a partial class named SaveService is created with a partial void function named SaveAndView with three parameters: the file name, file content type, and memory stream to write the file.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace PDF_Viewer
{
    public partial class SaveService
    {
        public partial void SaveAndView(string filename, string contentType, MemoryStream stream);
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace PDF_Viewer
{
    public partial class SaveService
    {
        public partial void SaveAndView(string filename, string contentType, MemoryStream stream);
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Text
Imports System.Threading.Tasks

Namespace PDF_Viewer
	Partial Public Class SaveService
		Public Partial Private Sub SaveAndView(ByVal filename As String, ByVal contentType As String, ByVal stream As MemoryStream)
		End Sub
	End Class
End Namespace

$vbLabelText $csharpLabel

Saving and viewing functionality will need to be implemented for each platform that intends to support (e.g., for Android, macOS, and/or Windows). For the Windows platform, create a file named "SaveWindows.cs" and implement the partial method SaveAndView:

using Windows.Storage;
using Windows.Storage.Pickers;
using Windows.Storage.Streams;
using Windows.UI.Popups;

namespace PDF_Viewer
{
    public partial class SaveService
    {
        public async partial void SaveAndView(string filename, string contentType, MemoryStream stream)
        {
            StorageFile stFile;
            string extension = Path.GetExtension(filename);
            //Gets process windows handle to open the dialog in application process.
            IntPtr windowHandle = System.Diagnostics.Process.GetCurrentProcess().MainWindowHandle;
            if (!Windows.Foundation.Metadata.ApiInformation.IsTypePresent("Windows.Phone.UI.Input.HardwareButtons"))
            {
                //Creates file save picker to save a file.
                FileSavePicker savePicker = new FileSavePicker();
                savePicker.DefaultFileExtension = ".pdf";
                savePicker.SuggestedFileName = filename;
                //Saves the file as PDF file.
                savePicker.FileTypeChoices.Add("PDF", new List<string>() { ".pdf" });

                WinRT.Interop.InitializeWithWindow.Initialize(savePicker, windowHandle);
                stFile = await savePicker.PickSaveFileAsync();
            }
            else
            {
                StorageFolder local = ApplicationData.Current.LocalFolder;
                stFile = await local.CreateFileAsync(filename, CreationCollisionOption.ReplaceExisting);
            }
            if (stFile != null)
            {
                using (IRandomAccessStream zipStream = await stFile.OpenAsync(FileAccessMode.ReadWrite))
                {
                    //Writes compressed data from memory to file.
                    using Stream outstream = zipStream.AsStreamForWrite();
                    outstream.SetLength(0);
                    //Saves the stream as file.
                    byte [] buffer = stream.ToArray();
                    outstream.Write(buffer, 0, buffer.Length);
                    outstream.Flush();
                }
                //Create message dialog box.
                MessageDialog msgDialog = new("Do you want to view the document?", "File has been created successfully");
                UICommand yesCmd = new("Yes");
                msgDialog.Commands.Add(yesCmd);
                UICommand noCmd = new("No");
                msgDialog.Commands.Add(noCmd);

                WinRT.Interop.InitializeWithWindow.Initialize(msgDialog, windowHandle);

                //Showing a dialog box.
                IUICommand cmd = await msgDialog.ShowAsync();
                if (cmd.Label == yesCmd.Label)
                {
                    //Launch the saved file.
                    await Windows.System.Launcher.LaunchFileAsync(stFile);
                }
            }

For Android and macOS, you've to create separate files with comparable SaveAndView implementations. You can get a working example from this MAUI PDF Viewer GitHub Repo.

Step 4: Code for PDF Functionalities

Now, it's time to write the code for the PDF functionalities. Let's start with the URL to PDF functionality.

URL to PDF Functionality

Create an UrlToPdf function for the URL to PDF functionality. Inside the function, instantiate the ChromePdfRenderer object and use the RenderUrlAsPdf function to convert the URL to PDF documents. The RenderUrlAsPdf function gets the data of the URL from the web server and processes it to convert it into a PDF document. In parameters, pass the text in the URL entry control, create an object of the SaveService class, and use the SaveAndView function. In the parameters of the SaveAndView function, pass in the stream of the generated PDF file.

The SaveAndView function helps to save files at any customized path and gives the option to view PDF files. At last, display an alert box with information about creating the PDF file. If a user tries to create a PDF file with an empty entry control, it'll display an alert box with an error message and warning.

private void UrlToPdf(object sender, EventArgs e)
{
    if (!string.IsNullOrEmpty(URL.Text))
    {
        var renderer = new IronPdf.ChromePdfRenderer();
        var pdf = renderer.RenderUrlAsPdf(URL.Text.Trim());
        SaveService saveService = new SaveService();
        saveService.SaveAndView("URLtoPDF.pdf", "application/pdf", pdf.Stream);
        DisplayAlert("Success", "PDF from URL Created!", "OK");
    }
    else
    {
        DisplayAlert("Error", "Field can't be empty! \nPlease enter URL!", "OK");
    }

}

private void UrlToPdf(object sender, EventArgs e)
{
    if (!string.IsNullOrEmpty(URL.Text))
    {
        var renderer = new IronPdf.ChromePdfRenderer();
        var pdf = renderer.RenderUrlAsPdf(URL.Text.Trim());
        SaveService saveService = new SaveService();
        saveService.SaveAndView("URLtoPDF.pdf", "application/pdf", pdf.Stream);
        DisplayAlert("Success", "PDF from URL Created!", "OK");
    }
    else
    {
        DisplayAlert("Error", "Field can't be empty! \nPlease enter URL!", "OK");
    }

}

Imports Microsoft.VisualBasic

Private Sub UrlToPdf(ByVal sender As Object, ByVal e As EventArgs)
	If Not String.IsNullOrEmpty(URL.Text) Then
		Dim renderer = New IronPdf.ChromePdfRenderer()
		Dim pdf = renderer.RenderUrlAsPdf(URL.Text.Trim())
		Dim saveService As New SaveService()
		saveService.SaveAndView("URLtoPDF.pdf", "application/pdf", pdf.Stream)
		DisplayAlert("Success", "PDF from URL Created!", "OK")
	Else
		DisplayAlert("Error", "Field can't be empty! " & vbLf & "Please enter URL!", "OK")
	End If

End Sub

HTML to PDF Functionality

For converting HTML to PDF functionality, create the HtmlToPdf function and use the RenderHtmlAsPdf function. Use the text of the Editor control and pass it in the parameters of the RenderHtmlAsPdf function. Similar to the above function, use the SaveAndView function to enable the functionality to view the PDF file after saving.

private void HtmlToPdf(object sender, EventArgs e)
{
    if (!string.IsNullOrEmpty(HTML.Text))
    {
        var renderer = new IronPdf.ChromePdfRenderer();
        var pdf = renderer.RenderHtmlAsPdf(HTML.Text);
        SaveService saveService = new SaveService();
        saveService.SaveAndView("IronPDF HTML string.pdf", "application/pdf", pdf.Stream);
        DisplayAlert("Success", "PDF from HTML Created!", "OK");
    }
    else
    {
        DisplayAlert("Error", "Field can't be empty! \nPlease enter valid HTML!", "OK");
    }
}

private void HtmlToPdf(object sender, EventArgs e)
{
    if (!string.IsNullOrEmpty(HTML.Text))
    {
        var renderer = new IronPdf.ChromePdfRenderer();
        var pdf = renderer.RenderHtmlAsPdf(HTML.Text);
        SaveService saveService = new SaveService();
        saveService.SaveAndView("IronPDF HTML string.pdf", "application/pdf", pdf.Stream);
        DisplayAlert("Success", "PDF from HTML Created!", "OK");
    }
    else
    {
        DisplayAlert("Error", "Field can't be empty! \nPlease enter valid HTML!", "OK");
    }
}

Imports Microsoft.VisualBasic

Private Sub HtmlToPdf(ByVal sender As Object, ByVal e As EventArgs)
	If Not String.IsNullOrEmpty(HTML.Text) Then
		Dim renderer = New IronPdf.ChromePdfRenderer()
		Dim pdf = renderer.RenderHtmlAsPdf(HTML.Text)
		Dim saveService As New SaveService()
		saveService.SaveAndView("IronPDF HTML string.pdf", "application/pdf", pdf.Stream)
		DisplayAlert("Success", "PDF from HTML Created!", "OK")
	Else
		DisplayAlert("Error", "Field can't be empty! " & vbLf & "Please enter valid HTML!", "OK")
	End If
End Sub

HTML File to PDF Functionality

Create the FileToPdf function for converting HTML files to PDF files. Use the RenderHtmlFileAsPdf function and pass the HTML file path as a parameter. It converts all HTML content into a PDF and saves the output file.

private void FileToPdf(object sender, EventArgs e)
{
    var renderer = new IronPdf.ChromePdfRenderer();
    var pdf = renderer.RenderHtmlFileAsPdf(@"C:\Users\Administrator\Desktop\index.html");
    SaveService saveService = new SaveService();
    saveService.SaveAndView("HTML File to PDF.pdf", "application/pdf", pdf.Stream);
    DisplayAlert("Success", "PDF from File Created!", "OK");
}

private void FileToPdf(object sender, EventArgs e)
{
    var renderer = new IronPdf.ChromePdfRenderer();
    var pdf = renderer.RenderHtmlFileAsPdf(@"C:\Users\Administrator\Desktop\index.html");
    SaveService saveService = new SaveService();
    saveService.SaveAndView("HTML File to PDF.pdf", "application/pdf", pdf.Stream);
    DisplayAlert("Success", "PDF from File Created!", "OK");
}

Private Sub FileToPdf(ByVal sender As Object, ByVal e As EventArgs)
	Dim renderer = New IronPdf.ChromePdfRenderer()
	Dim pdf = renderer.RenderHtmlFileAsPdf("C:\Users\Administrator\Desktop\index.html")
	Dim saveService As New SaveService()
	saveService.SaveAndView("HTML File to PDF.pdf", "application/pdf", pdf.Stream)
	DisplayAlert("Success", "PDF from File Created!", "OK")
End Sub
