Remarks
When exporting a document to PDF, you can control the resulting file size. Enable the PdfExportOptions.ConvertImagesToJpeg option to reduce the size of the resulting PDF document by compressing the original images to JPEG.
In this case, you can use the ImageQuality property to specify the required quality of PDF-embedded images. Increasing the quality of document images may result in a large file size, and vise versa, degrading the quality reduces the file size.
