Compression no better than Preview/Export/Quartz Filter/Reduce File Size

Before you purchase this, try compression using Apple/Preview/Export/Quart Filter/Reduce File Size. This feature in Mac’s Preview compresses by the same percentage as PDF Squeezer in my experience so appears to have been a waste of money. Trying to figure out how to get a refund.
