Today I was searching for a tool which let me reduze the file size of saved pdf files. With the default installation of Leopard you will have a Quartz filter named “Reduze file size” for the “Save as” dialog in the Preview application. Using that filter results in a nearly unreadable pdf file. It shrinks the size too much so nearly nothing was readable, e.g. the 3MB grayscale image, which shows a paper with text, was reduced to only 32KB!!! Damn.
Digging into searches gives me following interesting discussion on Apple.com. It reports about some additionally filters for free. You can download and unzip them into your own or the systems library folder. That’s all! From now on you have better control about needed file sizes and quality while saving different formats as PDF.
