Yes. Click on the FILE tab at the top left of Microsoft Word. Then, click on the little arrow to the right of Save As. In the Save as type list, if you see a PDF option, then your computer already has the add-in for this function and you can save your file as a PDF by selecting that option. If you see a Find add-ins for other file formats option, then click on that as it means that you need to install the add-in.
Note: You will need Internet access as a download is required. Follow the on-screen instructions to download and install the add-in. Once this has been completed, you will be able to save in PDF format.
