Adjust the JPEG image quality Leave feedback

Decreasing the JPG images quality reduces the size of the output file.

To adjust images quality, set the Quality property of the JpgViewOptions class. The value must be between 1 (minimum quality) and 100. The default value is 90.

To set the image quality, follow these steps:

Instantiate the Viewer class. Specify the source document path as a constructor parameter.
Instantiate the JpgViewOptions object.
Set the Quality value.
Call the View method of the Viewer object. Specify the JpgViewOptions object as the parameter.

The following code snippet shows how to adjust quality of the output JPG image:

using GroupDocs.Viewer;
using GroupDocs.Viewer.Options;
// ...

using (Viewer viewer = new Viewer("sample.docx"))
{
    // Create a JPG file.
    JpgViewOptions viewOptions = new JpgViewOptions();
    
    // Specify the JPG image quality.
    viewOptions.Quality = 50;    
    viewer.View(viewOptions);
}

VB.NET

Imports GroupDocs.Viewer
Imports GroupDocs.Viewer.Options
' ...

Module Program
    Sub Main(args As String())
        Using viewer As Viewer = New Viewer("sample.docx")
            ' Create a JPG file.
            Dim viewOptions As JpgViewOptions = New JpgViewOptions()
        
            ' Specify the JPG image quality.
            viewOptions.Quality = 50
            viewer.View(viewOptions)
        End Using
    End Sub
End Module
