Large PDF files

After adding a background image (72DPI 1920x1200) the file size jumps from a pdf without of about 45MB to 190 MB.

Here's the link to the 163MB pdf:http://greenpeas.us/media/belight/NB2014sat2b.pdf

and the 8.9MB zipped disc cover file:http://greenpeas.us/media/belight/NB2014sat2b.zip

When uploading these, it looks like everything was converted to TIFF. could that be the issue?

Hi

Yes, you are right. The program can convert images to TIFF especially when you apply effects from the Image Tricks plugin. In your document, it is the background image which increases the PDF size so dramatically.

In my experiments, the created PDF was about 55 MB not 163 as you have. Without the background it takes 14 MB. When I open your document on my computer, I can see that all your fonts are replaced with some different. This may mean that the use of specific fonts can add more megabytes to the final PDF. To research this, you can create two copies of your document and save two test PDFs:
1. Convert text to curves before exporting to PDF.
2. Replace all fonts used with Helvetica.

If the test PDFs are about 55 MB, we'll find out if the font matters.
