Safari User Guide
Preview is the default app for viewing images and PDF files on your Mac. So, any time you double-click on, or otherwise launch, one of those files, it'll open in Preview. If, for some reason, another app has taken over responsibility for a certain file type, and you want to give it back to Preview, you make the change right in the Finder.
Download music, PDFs, software, and other items by clicking links on webpages.
Important: If a download contains software, an alert appears when you open the item. To be safe, don’t open it if you weren’t expecting a software program or if it’s not from a trusted source.
Download an item
In the Safari app on your Mac, click anything identified as a download link, or Control-click an image or other object on the page.
Choose Download Linked File. (Some webpage items can’t be downloaded.)
Safari decompresses files such as .zip files after it downloads them.
Note: If you download an item that you previously downloaded, Safari removes the older duplicate so it doesn’t take up space on your Mac. See Optimize storage space on your Mac.
