How to Make Chrome Use Less RAM and CPU

There’s no denying that Chrome can be a bit ofa resource hog at times, so we’ve created this guide to help you make Chromeless resource intensive.

These tips will help you to reduce the strain Chrome takes on your CPU and minimize the memory (RAM) the browser uses. Hopefully following these tips will help performance regardless of whether Chrome is in the foreground or running in the background.

We’ll start by looking at Google’s suggestedoptimization tips and then we’ll share some lesser known tools after.

Steps for Optimizing Google Chrome

Our first suggestion would be to install thelatest Google Chrome updates. This could include new optimizations and fixesfor potential incompatibilities with your current hardware.

To update Google Chrome, click the three dots in the top right. At the bottom, hover over ‘help’ and then click ‘About Google Chrome’.

This will take you to a page where you can seeif you need to update Chrome.

If there is an update available, you’ll benotified here and you’ll be able to update Chrome.

Once you’ve checked to see whether Chrome hasbeen updated, you can now move to Chrome’s built-in task manager. This menu issomething most people are unaware of and it can help you to reduce Chrome’smemory and CPU usage.

To access the task manager, click the three dots in the top right.Hover over ‘more tools’ and thenselect ‘task manager’. In TaskManager, you’ll be able to see which apps and tabs use the most memory and CPUpower within Chrome.

You may be surprised at some of the usagehere. For example, I had the Google Drive tab in the background and it wasusing 430MB of RAM and I wasn’t even using it. You can close down apps and tabshere or close task manager and then end them manually.

General Chrome Maintenance Tips

On top of these two tips, being more aware ofhow many tabs you have open at once can help Chrome to be less resourceintensive. Each tab has its own impact on your performance, so 10

or more tabs will only increase the strain onyour PC tenfold.

If you want to reduce the strain further, you could take apps you use outside of Chrome by downloading standalone software. For example, picking up Word, WordPad, or even the desktop version of Google Drive instead of using Chrome.

You could also use Spotify instead of YouTube for music. Consider using standalone apps for everything so that Chrome isn’t such a memory hog, and remember to close those apps when you aren’t using them.

Remove Extensions or Viruses

You can find potentially harmful apps orextensions installed on your Chrome browser by visitingchrome://settings/cleanup.

In some cases, malicious extensions may havebeen installed on your PC and this page shown above will remove them for you.Malicious extensions may make adverts pop up or make other processes run in thebackground that can increase the strain Chrome has on your PC.

Sometimes non-malicious extensions can have abig impact on your Chrome’s performance too. To check through your extensionsand remove those you don’t need, visit chrome://extensions/ and considerdeleting the ones you don’t need.

You may find that there are extensionsinstalled that you never even use and these could be running in the background.If you’re not sure what impact a particular extension may have on yourperformance, you can refer to the task manager we mentioned earlier. Extensionswill appear there, too. You’ll need to delete them from the extensions page,however.

Use Extensions to Manage Performance

After removing unneeded extensions, it mayseem counterintuitive to go and install more, but there are some extensionsthat can improve performance. We’ve picked out three below that people may beunaware of. All of these are designed to help monitor and reduce the strainChrome has on your PC.


OneTab is a Chrome extension that can move allof your open tabs into a single list. You can then use the list to re-open orclose tabs at any point. The list won’t take much of an impact on yourperformance and it is far better than having all of those tabs open and runningin the background.


Tab Wrangler is another option, specifically aimed at those that forget to close all of their tabs. It will close tabs automatically after they are left idle for a designated time.

You can also set certain apps, tabs or websites to never close and set up more rules so that everything is automated. Eventually, all you have to worry about is browsing and Tab Wrangler will do the rest for you.

TheGreat Suspender

The Great Suspender is similar to Tab Wrangler, but instead of closing tabs, The Great Suspender will simply suspend tabs you aren’t using. This means that you can browse with lots of tabs open without impacting performance.

When you switch tabs, those tabs will start running like normal again. There are settings available to whitelist certain websites or stop pinned tabs from being suspended, so you have a lot of control over how the extension works.


That wraps up our guide on how to make Chromeless resource intensive. We hope that this guide has been useful. If you needsome more tips or advice, leave a comment and I’ll try to help when I can.
