"My PDFs are coming out too Big! Something that should be less than a megabyte is coming out huge and too big to email"
For other graphic designers out there who can’t understand why a simple PDF is coming out much larger than it should be, NO it’s not you. This is just a layering glitch that Adobe has never really completely fixed. Here is an unbelievably simple trick.
Rather than trying to optimize your PDF therefore bringing down the over all quality of it, try this. Simply resave the PDF after you export it and you will find that 75% of the time the size if it will drastically reduce to a manageable size without jumping any hoops or sacrificing the quality level of your document.
