Chrome Is Slow and Uses Too Much RAM: 8 Fixes

Chrome lags, fans spin, and tabs reload constantly. Make Chrome fast again without losing your data.

Chrome gets slow from too many extensions, dozens of open tabs, and accumulated site data. These fixes keep your bookmarks and passwords safe.

Steps

1Remove extensions you don't use
Go to chrome://extensions and remove everything non-essential. Keep at most an ad-blocker and password manager.
2Turn on Memory Saver
Go to Settings > Performance and enable Memory Saver so inactive tabs sleep.
3Clear cached site data
Settings > Privacy > Clear browsing data > Cached images and files (keep passwords and history).
4Close tabs with a tab manager
Bookmark tab groups or use OneTab-style session saving instead of keeping 40 tabs open.
5Disable hardware acceleration if glitchy
If pages flicker, toggle off Settings > System > hardware acceleration and restart Chrome.
6Update Chrome
Go to Help > About Google Chrome and install pending updates.
7Scan for harmful software
Use Settings > Reset and clean up > Clean up computer on Windows.
8Create a fresh profile if needed
Add a new Chrome profile and sign in - a corrupted profile causes permanent slowness.
