PDF Architect Large File Size

I have a jpg that is 4800pixels x 3000pixels. With a medium high compression it is a 4 MB file size. when I use PDF Architect Free to create a PDF from the jpg the resulting PDF is 34 MB. Is there a way for me to control this? I don't want such a large file size for the resulting PDF.

I am new to PDF Architect and trying to get away from Adobe Acrobat Pro. Acrobat Pro does not have this behavior/problem (but it's too expensive for my needs).

Thanks for any help
