How do I compress a PDF that totals 300K MB? I don't have access to the original file, which was created in Illustrator. I'm using Mac 10.5.8 and Adobe Reader X.
Adobe Reader can't compress PDF files. You may try Adobe Acrobat.
Using Acrobat X, I've saved a file as "Reduced Size PDF" -- is it possible
further reduce this file size?
You can try the PDF optimizer.
