How to Make Chrome Less Resource Intensive

If Chrome is eating your RAM and slowing down your computer, this guide will help you reduce its resource usage. You’ll learn to adjust settings, manage extensions, and use built-in tools to make Chrome faster and lighter, without losing your bookmarks or passwords.

What You’ll Need

A computer with Google Chrome installed (Windows, Mac, or Linux)
Admin rights to change system settings (optional, for some steps)
About 10–15 minutes of your time

Step-by-Step

Open Chrome’s Task Manager. Press Shift + Esc (Windows) or Shift + Esc (Mac) to see which tabs and extensions are using the most memory. Alternatively, click the three-dot menu > More tools > Task Manager. Note the heaviest items—these are your main culprits.
Close unused tabs. Every tab is a separate process. Close tabs you don’t need, especially those with heavy content like YouTube, Gmail, or Google Docs. Use a bookmark manager to save important pages for later.
Enable Memory Saver (Chrome 108+). Go to Chrome settings (three-dot menu > Settings). Under “Performance,� turn on “Memory Saver.� This feature automatically frees memory from inactive tabs. You can also choose to keep specific sites always active by clicking “Add� under “Always keep these sites active.�
Disable or remove unnecessary extensions. Type chrome://extensions in the address bar. Review the list and toggle off any you don’t use daily. Remove extensions that duplicate built-in features (e.g., a PDF viewer, ad blocker, or password manager). Each extension runs in the background and consumes memory.
Use a lighter ad blocker. Ad blockers can be heavy. If you have one, try switching to a more efficient option like uBlock Origin (if available) or use Chrome’s built-in “Ad privacy� controls (Settings > Privacy and security > Ad privacy). You can also disable the ad blocker on sites you trust to reduce its load.
Limit background activity. Go to Settings > Performance > “Preload pages� and select “Standard preloading� (or turn it off entirely). Also, go to Settings > System and turn off “Continue running background apps when Google Chrome is closed� if you don’t need background apps.
Disable hardware acceleration if it causes problems. Hardware acceleration can sometimes cause high GPU memory usage. Go to Settings > System and toggle off “Use graphics acceleration when available.� Restart Chrome and see if memory usage drops. (If it doesn’t, turn it back on.)
Clear browsing data. Over time, cache and cookies can bloat your profile. Go to Settings > Privacy and security > Clear browsing data. Choose “All time� and clear cached images and files, but keep cookies if you want to stay logged in. This can free up disk space and improve performance.
Use a single profile. Multiple Chrome profiles (e.g., Work and Personal) each run separate processes. Use one profile with multiple windows, or sign in to different accounts in the same window (using “Switch person� but keep the same profile).
Restart Chrome regularly. Chrome has memory leaks over long sessions. Close and reopen Chrome every few days to reset memory usage. You can also use the “Restart� option in the three-dot menu (if available) to quickly restart with your open tabs restored.
Update Chrome. Always keep Chrome updated to the latest version. Updates often include performance improvements and bug fixes. Go to three-dot menu > Help > About Google Chrome to check for updates.
Consider a lighter browser for heavy tasks. If Chrome still feels heavy, use a lightweight browser like Firefox or Edge for simple tasks (reading articles, checking email) and reserve Chrome for sites that need it (like Google Workspace).

Common Mistakes

Disabling Memory Saver entirely. Some users turn it off because they want tabs to reload instantly, but this defeats the purpose. Instead, add important sites to the “always keep active� list.
Installing too many extensions. Even if you don’t use them, extensions can run in the background. Be ruthless—remove any you haven’t used in the last month.
Not checking the Task Manager. You might guess which tabs are heavy, but the Task Manager shows the truth. Always check it first.
Clearing cookies unnecessarily. Clearing cookies logs you out of sites. Only clear cached images and files, not cookies, unless you want to sign in again.
Turning off hardware acceleration permanently. This can reduce GPU memory but may make video playback or scrolling less smooth. Test it before leaving it off.

Tips

Use tab groups. Group related tabs (e.g., work, research) and collapse them. This reduces visual clutter and can help you close unused groups faster.
Bookmark heavy pages. If you regularly open a heavy site (like a dashboard), bookmark it instead of keeping it open. Open it only when needed.
Use the “Snooze� feature. Right-click a tab and select “Snooze� to temporarily hide it and have it reopen later. This is great for articles you want to read but don’t need right now.
Monitor resource usage over time. Use Chrome’s Task Manager occasionally to see if any extension is leaking memory. If one consistently shows high memory, consider replacing it.
Use a separate browser for video calls. Video conferencing apps (like Meet or Zoom) can be resource-heavy. Using a different browser for calls can reduce Chrome’s load.

Troubleshooting

Chrome still uses a lot of memory after following these steps? Check the Task Manager again. If a specific tab (like a Google Docs tab) is using an unusually high amount, try closing it and reopening it. If an extension is the culprit, disable it and see if memory drops. If nothing helps, try resetting Chrome settings (Settings > Reset settings > Restore settings to their original defaults). This will disable all extensions and reset shortcuts, but keeps your bookmarks and passwords.

Memory Saver isn’t working? Make sure you’re on Chrome 108 or later. You can check by going to Help > About Google Chrome. If it’s enabled but tabs still reload often, you might have too many tabs open. Close some, or increase your system’s RAM if possible.

Hardware acceleration causes screen flickering? Turn it off permanently. This is a known issue on some GPUs. You can also try updating your graphics drivers.

Chrome crashes after disabling extensions? Re-enable extensions one by one to find the problematic one. If a specific extension causes crashes, remove it and look for an alternative.

Background apps still running? If you turned off “Continue running background apps� but apps still run, check the system tray (Windows) or menu bar (Mac) for Chrome icons. You may need to quit Chrome completely (right-click the icon and select “Exit�).

Frequently Asked Questions

Why does Chrome use so much RAM?

Each tab, extension, and plugin runs as a separate process to improve stability and security. This design uses more memory, especially with many tabs or heavy extensions.

Does Memory Saver affect my open tabs?

It puts inactive tabs to sleep, so they don’t use CPU or memory. When you click on a sleeping tab, it reloads. You can add sites to “always keep active� to prevent this.

Will disabling extensions lose my data?

No, disabling an extension just turns it off. Your data (like passwords saved in a password manager) remains intact. Re-enable it later if needed.

Can I make Chrome use less memory without losing my bookmarks?

Yes, all the steps above (except clearing browsing data) preserve your bookmarks. Clearing cache and cookies doesn’t affect bookmarks either.

Is there a way to limit Chrome’s memory usage?

Chrome doesn’t have a built-in memory limit, but you can use the Task Manager to manually kill heavy processes. Third-party tools like “The Great Suspender� (now discontinued) or “OneTab� can also help, but use them with caution.

Does using a 64-bit version of Chrome help?

Yes, 64-bit Chrome can handle more memory efficiently and is generally more stable. Most modern systems have 64-bit versions, but you can check in Help > About Google Chrome.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
