What is a Browser Cache? (And Why Should I Care?)

how do I clear my browser cache?

Can’t see updates to your website? “Did you clear your browser cache?” Has your website designer asked you that?

Clients will ask me to make changes to their website, and when I let them know the changes have been completed, I often remind them to clear their browser cache to view the change.  Why? Because often they’ll say, “I don’t see the change,” if they don’t.

What is clearing your browser cache? And “How do I clear my cache?” is a question I often hear.

For those unfamiliar with what a browser cache, much less how to clear it, here’s a primer that might be helpful to you.


To help display web pages you’ve visited before quickly, your browser (such as Internet Explorer, Google Chrome, Safari, Firefox, etc.) will store a copy of the page in your browser’s cache (pronounced /kæʃ/, like “cash” ). So when you enter that web site address (i.e., URL) again, your browser will serve up the version of the page you last visited.

Therefore, you may not see a recent change that was made on your web page. To be sure you are retrieving the most recent version of this web page after you’ve made updates, you can “clear your browser cache” so your browser goes out and displays the current version.


The instructions vary from browser to browser, so we’ve listed the steps for some of the commonly used ones. For those not listed, the steps are similar for other browser. Look for the similar menu items.
