 # Unload the document in Pdf Viewer
 
-PDF Viewer allows you to unload the PDF document with the  [Unload(Boolean)](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.PdfViewerControl.html#Syncfusion_Windows_PdfViewer_PdfViewerControl_Unload_System_Boolean_) method of the [PdfViewerControl](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.PdfViewerControl.html) and [PdfDocumentView](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.PdfDocumentView.html) classes.This method includes an optional Boolean parameter to control the disposal of the loaded document.When the parameter is set to true, the method fully disposes of the loaded document, releasing all associated memory and resources. By default, the parameter is set to false, which unloads the document without disposing of it completely, allowing it to be reused if needed.The following code sample illustrates the same.
+The WPF PDF Viewer also allows a user to Unload the PDF document using [Unload()](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.PdfViewerControl.html#Syncfusion_Windows_PdfViewer_PdfViewerControl_Unload) API of the [PdfViewerControl](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.PdfViewerControl.html) and [PdfDocumentView](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.PdfDocumentView.html) classes.
+A user can dispose the PDF document by passing the Boolean parameter as ‘true’ to the [Unload(Boolean)](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.PdfViewer.PdfViewerControl.html#Syncfusion_Windows_PdfViewer_PdfViewerControl_Unload_System_Boolean_) API. The below code illustrates how to dispose the PDF document programmatically.

-N>* In PdfViewerControl, it is recommended not to unload the PDF document externally when loading a new PDF document, as the control internally handles the unloading process.
