Chrome Memory Saver reduces RAM use by putting inactive tabs to sleep. The tab stays visible in the tab strip, but Chrome frees much of the memory behind it until you click the tab again. On lower-memory computers or busy laptops, that can make the whole system feel more responsive.
Does this affect you?
Use this for Google Chrome on Windows or Mac, version 110 or later, when Chrome uses too much memory or dozens of open tabs slow the computer down. Memory Saver helps background tabs; it does not make an actively heavy page lightweight while you are using it.
Turn on Memory Saver
Some Chrome versions enable Memory Saver automatically and others leave it off, so it is worth checking.
- Click the three-dot menu in Chrome.
- Open Settings.
- Choose Performance from the left menu.
- Turn on Memory Saver.
- If Chrome shows an inactivity delay option, choose how soon inactive tabs should be put to sleep.
A shorter delay frees memory faster. A longer delay reduces how often background tabs need to reload when you return to them.
Keep specific sites from being put to sleep
Use the exception list for pages where losing live state would be annoying or risky.
- Open Settings > Performance.
- Find Always keep these sites active.
- Click Add.
- Enter the site address, such as mail.google.com.
- Repeat for webmail, music players, upload pages, dashboards, or forms you leave open often.
Sites on this list stay loaded even when they are not the active tab. That uses more memory, but it protects important pages from reloading at the wrong time.
More control
Know what a sleeping tab looks like
Hover over an inactive background tab. Chrome may show that the tab was inactive to save memory. When you click it, the page reloads and may take a moment to become usable again.
Protect unsaved work
Sleeping tabs can lose unsaved form text, half-written comments, or in-progress uploads because the page reloads from scratch. Add those sites to the active list before relying on Memory Saver.
Find the real memory hog
Memory Saver helps inactive tabs, but one active web app can still use a lot of RAM. Open Chrome Task Manager with Shift+Esc on Windows, or through More tools > Task Manager, and sort by memory to find the specific tab or extension.
Battery Saver is separate
Chrome Battery Saver appears near Memory Saver in Performance settings. It reduces background work and visual effects to extend battery life. You can use Memory Saver, Battery Saver, both, or neither.
