When it comes to saving space on your Mac computer, there are many things you can do — empty the trash, delete app installers, get rid of duplicate files, and more. 

You can also reduce the file size of PDF documents in order to make them more compact, and take up less space on your Mac.

However, it’s important to note that doing so may also decrease the quality of the original PDF.

If you need a high-quality PDF, for a presentation or work assignment, you may be better off using another space-saving method, like saving it to cloud-based backup system or an external hard drive.

But if you decide it’s the right way to go, here’s what you’ll need to do in order to reduce the file size of a PDF on your Mac, via the Preview app.
