Hi Lionelr,

You may try flattening transparency and then save pdf as optimized pdf as the following thread suggests and see if that works:

“the PDF document contained image masks that were not downsampled."

You may also visit the following forum threads which discuss the similar issue:

How can I reduce the size images on a PDF?

Thanks,

Shivam

    What does AUDIT SPACE USAGE show as the main users of space? And the pictures on this page? Are they black/one colour, or normal multicolour?

    I make this form for reports.

    This is for one report only.

    Do you feel this is stopping the size reduction you want?
