Decrease Size of PDF on Mac with Free Preview

Preview is the free mac tool to manage PDF and image files, it is also capable of reducing a PDF file size.

However, according to my tests, Preview only works on this issue when I drop files mainly about images. If a file is evenly composed of texts, images, other elements, Preview gets only poor results (make your file even bigger)
