PDFs often have to be reviewed both for overall appearance as well as for correct content. PDF content may look different in different PDF programs. Exporting a PDF to an image PDF where each page is simply an image will guarantee correct and consistent rendering of the PDF in any PDF viewing program – in exactly the same way the PDF will be printed on a modern output system.
To open the Switchboard, click on the menu item "Switchboard" under the "View" menu or use the keyboard short cut "Ctrl-2" or "Cmd-2". Then click on the "Document" group icon.
Click on the "Image export" icon to go to the image export action.
After having clicked on the "Execute" button, choose the location and name for the exported PDF. Make sure not to overwrite your source PDF.
Depending on the number of pages in the source document, the export may take a while. Typically it should take about 1 second per page.
After completing the export, please double check the size of the exported PDF. If the file size is more than you find acceptable, use the "Recompress" action in the "Images" group of the Switchboard, and apply JPEG compression. Choose between maximum quality for least lossy compression, or high quality if small file sizes are very important. Lower quality values will begin to introduce visible artifacts.
