How to Clear Browser Cache

What is a cache?

The term ‘cache’ refers to the portion of your hard drive dedicated to storing browser files that your browser thinks it may use again. Without this feature, your browser would operate more slowly since every website you opened would need to download a large number of files from scratch each time.

This includes elements like the website logo, background images, fonts, plus technical aspects such as CSS, HTML, and JavaScript. Cumulatively, these can add up to dozens, hundreds, or even thousands of files for just one website. The cache stores these files locally, so future website visits are quicker, improving your overall internet experience.

So, why clear cache?

Clearing your cache means deleting all the saved information from your local hard drive that has been stored in the cache. Some of the reasons why you may want to clear browsing history include:

Maximizing performance:

Depending on your settings, your cache can grow quite large and take up significant disk space on your computer. The more information saved in the cache, the slower your computer will be when browsing online. Deleting your cache can help increase website loading times and improve the performance of your device.

Viewing most recent pages:

In theory, whenever you revisit a website, your cache checks to see if it has changed so it can show you the most up-to-date pages. However, this doesn’t always happen: sometimes the cache will load its older stored pages instead, which means you may not see the newest version. By periodically clearing your cache, you force your browser to start afresh, ensuring that you view the latest pages and information.

Maintaining security:

If you are using a public or shared computer, clearing your cache may help protect your privacy. If you don't clear your cache, then anyone who uses the computer after you may be able to see your browser history. The cache can also store private data required by some websites, which could give the next user on the computer access to sensitive or personal information. The cache's temporary files may also be a target for adware, malware, and viruses.

Fixing browser errors:

Your cache can sometimes cause browser issues. For example, you may find that certain websites are slow to load or only partially load, will not open, return an error message, or otherwise don’t respond as they should. Often, you can fix these types of errors by clearing your cache before closing and reopening your browser.
