Convert PDF to Images has a Resolution (DPI) box (150 by default) instead of always using 150 DPI. Pick a value from the list or type any value; 96 is added to the list, which Save Selection As Image shares. Pages too large for the chosen DPI are refused (discussion #6283).

PDFs with JPEG XL images (JXLDecode streams) now render, and saving such a PDF keeps the images as they are.
