Chrome eating all your RAM? Here's what actually helps

Chrome runs each tab as a mostly separate process by design, which is great for stability one tab crashing doesn't take down the whole browser but it does mean memory use scales up fast with tabs and extensions both.

Find out what's actually using the memory

Chrome has its own built-in task manager, separate from your operating system's one. Type chrome://settings/performance in the address bar, or use Shift+Esc on Windows to open Chrome's Task Manager directly. This showed me that one single tab a web app I'd left open for days was using over 1GB on its own, more than all my other tabs combined.

Turn on Memory Saver

This is the setting most people never find, buried in chrome://settings/performance. Memory Saver automatically puts inactive tabs to sleep, freeing their memory until you click back on them, at which point they reload instantly. Turning this on alone got my RAM use down by close to half without me having to close anything manually.

Extensions add up more than people realize

Each extension runs continuously in the background, even on tabs that have nothing to do with what it does. chrome://extensions lets you see everything installed I found three I hadn't used in months still running. Disabling unused ones (rather than just ignoring them) freed up a meaningful chunk on its own.

Hardware acceleration: helps usually, but not always

Chrome offloads some rendering work to your graphics card by default, which is normally a good thing. But on some laptops with weaker integrated graphics, this can backfire and use more memory than it saves. Worth testing with it off if you've tried everything else: chrome://settings/system, toggle "Use hardware acceleration when available."

Tab groups, more than just organization

Not a memory fix directly, but grouping related tabs and collapsing groups you're not using makes Memory Saver's job easier and gives you a visual reminder of what's actually still open. I went from feeling like I had "way too many tabs" to a manageable handful of active groups, which made the whole RAM problem less urgent day-to-day.

If you're still maxed out: check total RAM

If you're running 4GB or 8GB of total system RAM, Chrome alone with a handful of tabs can realistically use most of it that's not really a Chrome problem at that point, it's a "this laptop is under-specced for modern browsing" problem. Worth knowing the difference before chasing settings that won't move the needle much.

What worked for me

Memory Saver plus disabling three unused extensions. Combined, that took Chrome from 6GB down to around 2.5GB with the same number of tabs open.
