Details

I have several PDF brochures done by a designer in PDF from illustrator, I can also get the original .ai files. Problem is they are image heavy and some are as big as 20meg. I need them reduced in size to the smallest possible while still retaining reasonably good image quality so can use on website and send by email. if your interest i can send some of the  files by dropbox share for you to look at.
