Quick Tip: How do I clear my browser cache?

9th February 2019 | 4 Minutes

As a client, you’ll probably hear this often – “Have you cleared your cache?”. It can be a very vague and confusing question. What on earth is my ‘cache’? How do I ‘clear it? Well, wonder no more. I’m here with a quick guide as to what your cache is and how/when to clear it.

What is a ‘cache’ and what does it do?

A cache is something a browser uses to temporarily store information about the website you are viewing. Files that are cached locally include any documents that make up a website, such as HTML files, CSS stylesheets, JavaScript scripts, as well as graphic images and other multimedia content. It does this to ‘remember’ what a website looked like, so if you were to visit it again, it wouldn’t have to re-download assets such as images and files. This helps to speed up load times and makes browsing through the web a lot quicker.

Why do I need to clear it?

As a freelance web designer, I have to make regular updates to the files that comprise your site in order to push a change or new feature live. If I change a file that your browser has cached, it’s going to keep serving the old, cached version of the file and you won’t see the most recent changes. Clearing the Cache and Cookies in a browser helps fix these issues.

How do I clear my cache?
