Why Google Chrome still uses so much RAM

If you’ve spent any time on the Internet, you’ve probably noticed that Chrome is a RAM monopoly. However, this is not so much a fact as an Internet meme. This has more to do with navigation jokes and less to do with actual data, much like the claim that Microsoft Edge is slow and outdated. Both were repeated so often that they began to seem true.

This isn’t to say that Chrome doesn’t use as much RAM as it needs; This is absolutely the case. This just means that RAM usage isn’t much of an issue in 2026, nor in 2016.

Websites and the way we use them have changed dramatically since the early days of the Internet. Browsing the web used to be a matter of going from one text-heavy page to another with the occasional photo or video. Today’s websites look more like applications than just web pages. Each one contains more information and allows for a much more versatile browsing experience, while the browser itself is meant to hold multiple tabs at once while running multiple extensions in the background.

All of these features add up and should all load instantly and work without issue. This means the browser’s creators have to make a decision: share memory and processes between tabs to save RAM, or give each tab and site its own process, which costs more memory but keeps things fast and stable. Google Chrome, like many other browsers, chooses the latter. And that’s a good thing.

By giving each website its own dedicated process in computer memory, Chrome not only ensures that your browsing remains fast and responsive. This also prevents browser-wide crashes. Anyone old enough to remember the early days of web browsing probably remembers the terrible feeling when your browser suddenly disappeared with all your work, while you were left staring at a small system message informing you that the browser had encountered a problem and needed to shut down.

Today’s browsers avoid this problem by keeping each site in its own process. A crashed site doesn’t bring down the entire browser, along with the other 20+ tabs you had open. This approach also contributes to security. Chrome runs each site in a sandbox process, and the operating system separates these processes, so a malicious page can’t easily peek into what’s happening in your banking or email tab. Some of that extra memory is the price of that wall between your tabs, and it’s a price most people would be happy to pay.

There is a common misconception that RAM usage should be kept as low as possible so that the computer runs smoother. In reality, unused RAM is wasted RAM. The whole point of memory is to hold whatever you want, quickly and smoothly, and a browser that fills it with prepared pages, media, and tabs does its job. PCMag says that 8GB of RAM should be enough for most general-purpose PCs, several times what a single browser typically needs, so the headroom is there to be used.

High usage isn’t the only warning sign: you could also have a memory leak. A memory leak occurs when a program reclaims memory and never returns it, so the number continues to increase for no good reason. Chrome’s built-in task manager (Shift + Esc) indicates which tab or extension is the culprit.

Chrome has its own built-in response. Memory Saver puts tabs you haven’t touched in a while to sleep and frees up the memory they were using, then reloads them when you click back. Since then, Google has rolled it out to everyone. You can find it in Chrome’s settings under Performance, and you can add sites that should never be put to sleep, like the one that streams your music.

Other browsers take a different path. Microsoft Edge runs on the same Chromium base as Chrome, so it uses a similar process model, but its sleeping tabs and power saver put inactive tabs to sleep to reduce memory usage. Firefox groups tabs into fewer shared processes and unloads tabs when your system is low on memory. Both are reasonable choices, and neither is a cure. A browser that gives you the same experience for a fraction of the memory would have to give up something along the way.

If Chrome seems slow, don’t just look at the memory number. Open the browser’s task manager and look for a tab or extension that keeps growing. If nothing happens, Chrome uses your RAM as intended and you can leave it alone. If things still seem slow, the cause could be something else entirely, like a disk almost full or a slow connection, and restarting the browser is a good first step.
