How To Clear Your Chrome Browser Cache on Mac

Your Chrome browser contains a folder where certain items that have been downloaded are stored for future use. Items like graphic images, photos, and entire web pages are examples of items that have been saved or “cached.” Let’s take a look at how to clear Chrome cache on Mac.

What is the Browser Cache?

Simply put, the cache is a component (software or hardware) that is used to temporarily store certain values for faster access in the future. The browser cache is actually a small database of files. It contains downloaded web page resources. Some if these include things like:

  • Images
  • Videos
  • CSS
  • JavaScript

The basic idea behind a cache works like this:

Your Chrome browser requests content from a web page (whatever web page you are currently on). If the content that your browser is requesting is not already in the browser cache, then it grabs it directly from a web server. However, if the content that it is requesting was previously cached, then the browser is able to bypass the webserver and load content directly from the cache.

This process happens every time you visit a website. Whether your browser is grabbing content from a server or from your cache depends on a couple of things.

  1. If cached content is considered “stale” or not. This depends on whether or not it has expired. This means the browser will access the webserver.
  2. On the other hand, if the content hasn’t passed its expiration date, it is considered “fresh.” This means the browser is accessing the data through the cache, without having to deal with the server.

Two more terms you want to be familiar with if you are trying to understand the browser cache better.

Validation: This is speaking about the content that needs to be checked against the most recent content version the server has. This works in determining whether the content is stale or not.

Invalidation: This is something that happens when content has been removed from a cache before the expiration date. This may be something that was forced by the server because content has changed.

How Browser Caching Works

The browser cache “mechanism” in your Chrome browser is used to store web page resources locally. There are a lot of upsides to making sure you have a clear Chrome browser cache. Some of the most important ones include:

  • Performance Gains
  • Minimizing Bandwidth Consumption
  • Faster Browsing Experience

Proper content caching is arguably the most effective way to improve user experience for all your website visitors.

When you visit a website, your Chrome browser checks if a copy of the files on the page is already in the cache. If they are, it saves the visitor some download time and the webpage will load faster. Browsers refer to its cache as “Temporary Internet Files.”

There are some cases though that you will run into where bypassing your Chrome browser’s cache will be preferred. In most cases clicking the refresh button will not get you the result you need because this is just reloading the page while still using the same old files from the cache.

Below are step-by-step instructions for clearing your Chrome browser’s cache on a Mac and forcing it to load all the freshest and latest data from a website.

Why You Need To Clear Your Chrome Browser Cache on Mac

Any website you visit is actually made up of hundreds, and oftentimes thousands of files. Even the websites that are highly optimized for speed will usually load a lot of files in order to display the content properly in your browser.

Your Chrome browser does its part to speed up the loading process by saving pieces of the website the first time you visit. Once those pieces are saved the Chrome browser can display the files stored in its cache much faster than it can pull fresh files from a server.

Therefore, next time you visit that site the load time will be much faster because the Chrome browser will serve up the files stored in the browser cache.

Disadvantages of Not Clearing Browser Cache

With that being said, caching files can have several disadvantages over time. It is a great idea to clear your Chrome browser cache every so often for the following reasons:

Maximize Speed and Performance: Even if you don’t spend a lot of time online over time you will build up a very large cache. For those of you who do spend a lot of time online for work or surfing the web your cache will build up even faster. This can affect the speed and performance of your computer. Clearing the Chrome browser cache frees up some space and may help speed things back up again.

Viewing Most Recent Pages: Every time you revisit a website your Chrome browser cache is supposed to check to see if the site has changed in any way so that it can serve you the most up-to-date pages. This doesn’t always work and sometimes the cache will serve you up old page versions.

Maintaining Security: This will come in particularly handy if you are using a shared or public computer. Clearing the cache after using the computer will help maintain your privacy by clearing out any personal data you may have used while browsing. It also clears out any personal data that the websites you have visited keep.

Fixes Browser Errors: There are situations sometimes when your cache can cause problems when you are using your Chrome browser. Some good examples of this would include:

  • Certain websites are slow to load.
  • Certain websites will not load at all.
  • You will receive error messages.
  • Get hung up at certain spots on the website.

In most cases, all of those problems and others can be fixed by clearing the cache. You then restart the browser as well if needed.
