What is browser cache and how to clear it

A hard refresh clears your browser cache for a specific page, which forces it to load the most recent version of that page. This could include new scripts, styles or features. Clicking the “Refresh/Reload” arrow on your browser address bar is not a hard refresh. Clearing cache is especially important when viewing a website that is in development.  Here are instructions to clear browser cache in Chrome, Safari, and Firefox:


  1. Open Google Chrome on your computer.
  2. Click on the three vertical dots (menu icon) located at the top-right corner of the browser window.
  3. In the drop-down menu, hover over “More tools.”
  4. In the submenu that appears, click on “Clear browsing data.”
  5. The “Clear browsing data” window will open. Ensure that the “Basic” tab is selected.
  6. In the “Time range” drop-down menu, choose the time period for which you want to clear the cache. If you want to clear the entire cache, select “All time.”
  7. Check the box next to “Cached images and files.” You can uncheck other options if you only want to clear the cache.
  8. Click on the “Clear data” button.

Google Chrome will now clear the browser cache for the selected time period. Once the process is complete, you can browse the web with a fresh cache.

Please note that clearing the browser cache may sign you out of websites and remove saved preferences.


  1. Open Safari on your Mac.
  2. Go to the menu bar and click on “Safari” (located on the top-left corner of the screen).
  3. In the drop-down menu, click on “Preferences.”
