SUMMARY PDF produced by Skanpage are quiete heavy, we should have a parameter to select image compression. For example, you can see what is proposed by this free software : https://www.naps2.com/

Unfortunately, Qt does currently not offer support for selecting the image compression when writing to PDFs. So it is not easy to implement as far as I know.
