That’s a savings of about 85% which is something every single recipient of your handouts will appreciate. That is a sweet savings! We went from 100MB to 15.4MB with about 30 seconds worth of effort. Now let’s have a look at the Get Info window of the new shrunk PDF: Choose that, give the new PDF document a different name to the original and save it. And the choice we want for this task, highlighted: “ Reduce File Size“. Okay, click to open up the menu and check out those glorious options:Ĭool choices, eh?
