+# How to Export Chart as Image in WinUI Chart
+This article provides a detailed walkthrough on how to export a [WinUI Cartesian Chart](https://www.syncfusion.com/winui-controls/cartesian-charts) as an image. You can export the chart view in your desired file format, with supported formats being **JPEG** and **PNG.**
+
+### Initialize SfCartesianChart:
+
+Set up the **SfCartesianChart** following the [ Syncfusion WinUI Cartesian Chart documentation.](https://help.syncfusion.com/winui/cartesian-charts/getting-started)
+ ```xml
+<StackPanel Orientation="Vertical">
+ <chart:SfCartesianChart x:Name="Chart" Background="White" IsTransposed="True" 
+                         Header="Daily Water Consumption Tracking">
+     ....
+     <chart:ColumnSeries ItemsSource="{Binding DailyWaterIntake}"
+                         XBindingPath="Day" 
+                         YBindingPath="Liters"
+                         ShowDataLabels="True">
+         <chart:ColumnSeries.DataLabelSettings>
+             <chart:CartesianDataLabelSettings Position="Inner"/>
+         </chart:ColumnSeries.DataLabelSettings>
+     </chart:ColumnSeries>
+ </chart:SfCartesianChart>
+
+     <Button x:Name="button" Content="Export as Image" Click="Button_Click" />
+ </StackPanel> 
+ ```
+
+### Export the Chart as an Image:
+
+ ```csharp
+private async void Button_Click(object sender, RoutedEventArgs e)
+  {
+      await SaveAsImageAsync(Chart, "chart.png");
+  }
+
+  private async Task SaveAsImageAsync(SfCartesianChart chart, string fileName)
+  {
+      if (chart == null)
+          return;
+
+      // Render the chart to a RenderTargetBitmap
+      var renderTargetBitmap = new RenderTargetBitmap();
+      await renderTargetBitmap.RenderAsync(chart);
+
+      // Get pixel data
+      var pixelBuffer = await renderTargetBitmap.GetPixelsAsync();
+      var pixels = pixelBuffer.ToArray();
+
+      // Determine file format and encoder
+      string extension = Path.GetExtension(fileName)?.ToLower() ?? ".png";
+      var encoderId = extension == ".jpg" || extension == ".jpeg"
+          ? BitmapEncoder.JpegEncoderId
+          : BitmapEncoder.PngEncoderId;
+
+      // Choose image save path
+      var folder = await Windows.Storage.StorageFolder.GetFolderFromPathAsync(@"D:\");
+      var picturesFolder = await folder.CreateFileAsync( fileName, Windows.Storage.CreationCollisionOption.ReplaceExisting);
+
+      // Encode the image
+      using (var stream = await picturesFolder.OpenAsync(FileAccessMode.ReadWrite))
+      {
+          var encoder = await BitmapEncoder.CreateAsync(encoderId, stream);
+
+          encoder.SetPixelData(
+              BitmapPixelFormat.Bgra8,
+              BitmapAlphaMode.Premultiplied,
+             (uint)renderTargetBitmap.PixelWidth,
+             (uint)renderTargetBitmap.PixelHeight,
+              96.0, // DPI X
+              96.0, // DPI Y
+              pixels);
+
+          await encoder.FlushAsync();
+      }
+  } 
+ ```
+
+**Note:** By default, the chart background is transparent. When using JPEG format, RenderTargetBitmap converts the transparent background to black. To resolve this, set the chart’s BackgroundColor to white or any preferred color.
