Ok so I was doing something in InDesign and exported it as a PDF. So I decided to do a CMD + I to see how big it was (thinking it was going to be only a few MBs), and the PDF is like 112MB ! The InDesign file itself is only about 30MB and I did use 6 pictures that total about 28MB all together. Why is the PDF so large? I thought one of the plessures of PDFs was the smaller file size, maybe I was wrong?
