Before getting starting with how to reduce PDF file size on Mac you must know that but following this method is going to reduce the quality of the PDF file. So if you are preparing your PDF file specifically for a presentation for your job or for an assignment, I do not recommend this method at all. Although if you are only looking to free up some storage on your Mac then perhaps it is a good option even though the sizes of images will be reduced a bit. And I’m also suggesting that you should at least save the original version into a cloud storage of yours. Doesn’t matter you don’t have to purchase a cloud storage, just use a free version such as Google Drive or iCloud, Mega, Pcloud and many other. As long as you have the original PDF file, you can do anything with the copy including reducing its size.
Note: reducing PDF file is not going to reduce the text, instead it is going to reduce the images which are within the PDF file. Vector images are not included in this category.
