Specify the JPEG image quality Leave feedback

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

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

To set the image quality, follow these steps:

1. Instantiate the Viewer class. Specify the source document path as a constructor parameter.
2. Instantiate the PdfViewOptions object.
3. Set the PdfViewOptions.JpgQuality value.
4. Call the View method of the Viewer object. Specify the PdfViewOptions object as the parameter.

The following code snippet shows how to adjust JPG image quality in the output PDF document:

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