Whenever you browse the web in Safari, the browser stores website data so that it doesn't have to download it again each time you revisit a site. In theory this should speed up your browsing experience, but there are some scenarios where you might want to clear the cache and start anew. Keep reading to learn how it's done on Mac, iPhone, and iPad.

There are a couple of situations where you might benefit from clearing Safari's cache.

If a site you regularly frequent has elements that have stopped working, or if a site has stopped loading completely, there may be a conflict between an older version of it that Safari has cached and a newer one.

Or perhaps you simply want to protect your privacy by wiping the slate clean and removing all the data associated with websites you've visited. Either way, here's how it's done on macOS and iOS.

How to Clear Safari's Cache on Mac

There are two ways to clear Safari's cache on a Mac. The first method outlined below deletes everything relating to a website you've visited, including not only the cached versions of the site, but also cookies and any other related data.

Method 1:

Launch Safari browser on your Mac.
Select Safari -> Preferences....
Click the Privacy tab and select Manage Website Data....
Select a website that is listed, then click Remove. To remove all website data from Safari, click Remove All.

Method 2:

Launch Safari browser on your Mac.
Select Safari -> Preferences....
Click the Advanced tab and check the box next to Show Develop menu in menu bar.
