When "reduce file sizes" is invoked, image quality degrades substantially, even for onscreen viewing.  Is there a way to control image quality when file sizes are reduced, such that onscreen viewing quality is good for creation of PDF files?

    The greatest percentage of file size, in most cases, is the size of the included images. "Reduce File Size" works by reducing the resolution (and consequently, the file size), on these images.

     

    The only way I'm aware of to control the image quality is to do the reduction outside Pages, in iPhoto, or a similat application.

     

    Regards,

    The Pages Help and Manual mention the reduction is to 72 dpi for images which is very low, to produce the maximum file size reduction.

     

    You can use Preview .app to both crop and reduce the resolution of the images, then place them into Pages. Usually 150dpi at the used scale is a happy compromise.

     

    Cropping often does a great deal to reduce file size because "Reduce File Size" does not crop away the unseen portion of the image which adds unnecessarily to file size.

    Sounds your images are taking a double hit. The initial low quality setting and the downsizing to 72 dpi.

     

    Try using the images at best quality and then letting Pages downsize them.

     

    An 8 page newsletter is quite manageable for image replacement pre-publishing. Be systematic and use this method:

     

    click on cropped masked image in Pages > Copy > switch to Preview > command n > Save as > Format: Jpeg > Quality: near best (default) > Resolution: 150 (default) > OK > Copy > Paste back into Pages

    Ignore the Reduce File Size option inside Pages.

     

    Using Pages you might experiment with File>Export>PDF> Good/Better/Best

     

    BEST size is the largest and highest resolution. Better and Good compress the images.  Compare the relative sizes using CMD-I.

     

    good luck
