Chrome using too much memory: why it happens and how to reduce it

Applies to: Google Chrome on Windows 11, with the same settings on Windows 10. This guide is about Chrome using a lot of RAM and slowing things down. If Chrome doesn’t start at all, see Chrome won’t open in Windows 11; if tabs crash with an error page, our Aw, Snap! guide is the better fit.

Why Chrome uses so much memory

Chrome runs tabs, extensions and some of its own services as separate processes. That’s why Windows Task Manager can list a long group of chrome.exe entries for a single window. Keeping them apart means one broken page can crash without taking every other tab with it, but each process needs its own share of memory, so the total grows with every tab and add-on you keep open.

Some of that memory is simply in use for pages you’ve loaded, and Windows can still hand RAM to other apps when they need it. So treat the total as a clue, not a verdict. The time to act is when typing lags, tabs reload often, other programs slow down, or Chrome itself shows a performance alert.

Match your symptom

What you see	Likely cause	Go to
Memory jumps when one site is open	A single heavy page, such as a web app or video	Fix 1
Memory climbs slowly over the day with many tabs	Idle tabs kept loaded in the background	Fix 2
High memory even with only one or two tabs	Extensions, each running in its own process	Fix 1, Fix 3
chrome.exe still uses memory after you close every window	Background apps and extensions keep Chrome running	Fix 4
Chrome and the graphics side of Windows both use a lot	Hardware acceleration or a graphics driver problem	Fix 5
New tabs, pop-ups or a changed search engine along with high use	Unwanted software or a rogue extension	Fix 7
Everything is slow, not only Chrome	The PC is short of RAM overall	When the whole PC is short of memory

Fix 1: Find the heavy tab or extension

Windows Task Manager only shows Chrome as one large group. Chrome has its own Task Manager that breaks the total down by tab, extension and service, which tells you exactly what to close.

1. In Chrome, press Shift + Esc. You can also open it from the three-dot menu: More tools > Task manager.
2. Select the Memory footprint column heading to sort the list so the largest entries are at the top.
3. Select a tab or extension you can spare and choose End process. A tab you end shows an error page; reload it when you need it again.

Chrome’s Task Manager and its column names aren’t described on the Google pages listed under Official sources, so labels may differ slightly between versions. If one site tops the list every time, it’s the page itself. Keep it in a single tab, close it when you’re done, or check whether the site offers a lighter mode.

For a quicker check without opening a tool, Google’s Chrome performance settings page describes a memory readout on the tab preview: go to Settings > Appearance and, under Tab hover preview card, turn on Show tab memory usage. Hovering over a tab then shows how much memory it uses.

Fix 2: Turn on Memory Saver

Memory Saver deactivates tabs you haven’t used for a while and reloads them when you return, according to Google. It suits people who keep dozens of tabs open for reference.

1. Open Chrome, select More (the three dots), then Settings.
2. Choose Performance on the left.
3. Turn on Memory Saver.
4. Pick a level. Google lists Moderate (smallest savings, tabs wait longer before deactivating), Balanced (marked as recommended) and Maximum (largest savings, tabs deactivate soonest).

Start with Balanced. If tabs still pile up and the PC stays slow, try Maximum; if reloading tabs gets in your way, step down to Moderate. The Inactive tabs appearance option marks deactivated tabs with a ring around their icons, so you can see what Memory Saver is doing.

Some tabs aren’t deactivated on purpose. Google’s list includes tabs playing audio or video or in a call, screen sharing, pages that send notifications, active downloads, partly filled forms, pinned tabs, and pages connected to USB or Bluetooth devices. If memory stays high with Memory Saver on, check whether your heaviest tabs fall into one of those groups.

To protect a site you never want reloaded, such as a web app with unsaved work, select Add next to Always keep these sites active on the same page. You can pick from open tabs or type an address. Each site added here is one Memory Saver can’t help with, so keep the list short.

Google’s page also describes Performance issue alerts, on by default: when browsing slows, Chrome may suggest deactivating tabs, and Fix now accepts. That’s a reasonable shortcut when it appears.

Fix 3: Remove extensions you don’t need

Every extension adds work that runs alongside your tabs, and some keep running on every page you visit. Google’s crash and slowdown troubleshooting page recommends uninstalling extensions you don’t need when Chrome runs low on memory, and, if a problem persists, removing all of them and adding them back one at a time.

1. Use Chrome’s Task Manager from Fix 1 to see which extensions use the most memory.
2. Open the three-dot menu, then Extensions > Manage Extensions.
3. Select Remove for any extension you don’t use, or switch it off to test without uninstalling.
4. Watch memory use for a while with the reduced set before adding anything back.

Be careful with tab-suspender and “memory cleaner” extensions. Memory Saver already does the same job inside Chrome, and an extra extension is one more process plus another program with access to your pages.

Fix 4: Stop Chrome running after you close it

If chrome.exe still uses memory in Windows Task Manager after you close the last window, extensions or web apps may be keeping Chrome loaded. Go to Settings > System and turn off Continue running background apps when Google Chrome is closed. This switch isn’t covered on the Google pages listed below; it’s the same setting our Chrome won’t open guide uses for stuck processes.

Turning it off means features that rely on Chrome staying open, such as some extension notifications, stop when you close the browser. To quit everything at once, Google’s page gives Ctrl + Q on Windows, and Ctrl + Shift + T brings back your tabs when you reopen Chrome.

Fix 5: Test hardware acceleration

Hardware acceleration hands drawing work to the graphics card. With a faulty or outdated graphics driver, that can go wrong, and Google lists turning it off as a troubleshooting step. Treat this as a test rather than a permanent change, because without it the processor does that work and video playback can get heavier.

1. Open Settings > System in Chrome.
2. Turn off Use hardware acceleration when available.
3. Restart Chrome and compare memory use and smoothness over a normal session.

If things improve, update your graphics driver and then turn the setting back on. If Desktop Window Manager also uses a lot of memory at the same time, the graphics driver is worth checking; our guide to Desktop Window Manager high memory covers that side.

Fix 6: Review preloading and Energy Saver

Two more switches on the Performance page affect how much work Chrome does in the background:

• Preload pages: Chrome loads pages it thinks you’ll visit next so they open faster. Google offers Standard preloading and Extended preloading. Loading pages you may never open takes some resources, so on a PC that’s short of memory, Standard or off is a sensible choice. This is our reasoning; Google’s page doesn’t state how much memory preloading uses.
• Energy Saver: on a laptop, Energy Saver reduces background activity and stops eligible background tabs that use a lot of CPU. Google says it turns on when the device is unplugged or the battery is low, and not while plugged in. It targets battery life and processor load rather than memory, so it complements Memory Saver rather than replacing it.

Fix 7: Update Chrome and check for unwanted software

An out-of-date version can miss fixes, so open the three-dot menu, go to Help > About Google Chrome, let it check for updates, and select Relaunch if asked.

High memory paired with new tabs you didn’t open, pop-ups or a changed search engine points to unwanted software. Google’s troubleshooting page links to its guide on removing unwanted software, and Microsoft’s PC performance tips suggest a Quick scan in Windows Security > Virus & threat protection. Our guide on how to scan for malware walks through the built-in options. Remove any extension you don’t recognize at the same time.

Clearing cookies and cached files is a frequent suggestion for this problem, but the cache lives on disk, so it’s unlikely to lower memory use much and it signs you out of sites. Save it for pages that load wrongly.

Known issues: as of November 2026, we haven’t found a current Chrome memory problem on Windows 11 confirmed on an official Google or Microsoft page. If memory use jumped right after an update and none of the fixes help, report it from Chrome’s Help > Report an issue menu so Google receives the details.

When the whole PC is short of memory

Sometimes Chrome is only the most visible app on a PC that doesn’t have much RAM to spare. Microsoft’s performance tips cover the Windows side:

• Open Windows Task Manager with Ctrl + Shift + Esc and check the Memory column for other programs using a lot, then close the ones you don’t need.
• On the Startup apps page of Task Manager, disable programs you don’t need at sign-in so they don’t sit in memory all day.
• Install pending updates in Settings > Windows Update, including optional driver updates.
• Close unused apps and tabs and restart the PC if it’s still slow, as Microsoft suggests.

If the PC also stays busy with the disk light on, low memory can push Windows to use the disk more, and our guide to 100% disk usage on Windows 11 helps you check that. Microsoft notes that older hardware may see little benefit from tuning; on a PC with little RAM that you use for many tabs at once, a memory upgrade can be the longer-term fix.
