What is Browser Cache?

When you first visit a web page, your browser will make a copy of it (or elements of the page) and store it on your computer.  Browsers do this because this is quicker than downloading each element of the page over again each time you visit the page.  It is quicker to fetch a copy of something from your computer’s hard-drive than to download it over the internet.

Why Clear Browser Cache?

Overall, browser cache is a good thing as it helps load web pages faster, though in some cases you may want to wipe the browser cache stored on your computer so you can download a fresh copy of a web page.  An example of such a case would be if you changed an image on your page to a different image, but you were still seeing the old image when you view the page.  In this case you would try doing a “hard refresh” (see below for how) and if that does not work, you would clear your browser cache.

How to do a “Hard Refresh”

A hard refresh attempts to bypass the cached files your browser has stored on your computer.  This is how to do this on major browsers.

  • Google Chrome & Firefox: Hold down the “Ctrl” key on your keyboard and press the “F5” key.
  • Internet Explorer / Edge: Hold down the “Ctrl” key on your keyboard and press the “F5” key.
  • Safari (Mac): Hold down the “Shift” key while clicking on the reload button.
How to Clear the Cache
