Chrome is not automatically the biggest memory user on your computer—and there is no reliable universal ranking of apps that use more RAM than it. The answer depends on what is open, what each app is doing, and how your computer handles background work. Check your own processes and overall memory status before deciding what to close or whether you need more RAM.
Why apps besides Chrome can use memory
RAM is used by running processes, not just the windows you can see. Apple describes Mac processes as apps, system apps used by macOS, and invisible background processes. A browser with many active tabs may use substantial memory, but a video editor, messaging app, cloud-sync tool, or other program can also use memory depending on its workload and settings. That does not make any of them universally worse than Chrome.

Memory use changes with the app version, operating system, device, open content, and background behavior. A high number beside one process is a useful clue, not proof that it is causing a slowdown. Check whether the system is under memory pressure and whether the symptom changes when you quit an app you no longer need.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsCheck memory use on Windows
- Press Ctrl+Shift+Esc to open Task Manager.
- In Processes, review the Memory column to see current use by process. Select the column heading to sort the list and identify the largest users.
- Open Performance for a broader view of memory and other system resources. If the computer is sluggish, also check CPU and disk activity rather than assuming RAM is the only cause.
- Open Startup apps and disable automatic startup for apps you do not need immediately. This can reduce the work that starts with Windows; it does not prevent you from opening the app when you want it.
Some supported apps have background-activity permissions in Windows settings. Restricting background activity can affect notifications, synchronization, or updates, so change it only for apps whose background behavior you are willing to limit. Microsoft recommends monitoring resource use, closing apps that are not in use, and reviewing startup and background activity when troubleshooting performance.

Check memory use on a Mac
- Open Activity Monitor and select the Memory tab.
- Sort the process list by memory use, or search for a process by name. The list includes visible apps as well as system and background processes.
- Check Memory Pressure, along with swap and compressed memory, to assess the system as a whole.
- If pressure is elevated, identify an app using substantial memory and quit it only if you no longer need it. Avoid force-quitting unfamiliar system processes.
Apple says green Memory Pressure indicates efficient RAM use, yellow suggests the Mac might eventually need more RAM, and red indicates it needs more RAM. Free memory alone is not a complete performance diagnosis; Memory Pressure and the surrounding indicators give better context.
What to do when you find a large memory user
- If you are not using the app: quit it normally and see whether the slowdown improves.
- If it is needed but runs at startup: consider disabling its automatic startup, then open it when needed.
- If it needs background access: weigh the memory or performance benefit against features such as notifications, syncing, and updates before restricting it.
- If the computer remains slow: check CPU and disk activity too. A process using the most RAM is not necessarily the cause of the problem.
Compare what is happening before and after a change rather than treating one memory reading as a verdict. If one app repeatedly coincides with the symptom, update it through its normal channel or consult its support guidance; the process list by itself cannot establish a memory leak.

When more RAM may help
More RAM can support more simultaneous activity, but it is not a guaranteed fix for every slowdown. Microsoft’s general guidance says 4 GB is a suggested minimum for primarily browsing, working on documents, or streaming video online; 8 GB is recommended for keeping a device running long term; and 16 GB or more may suit photo or video editing and other high-performance projects. These are general recommendations on Microsoft’s support page, which does not state a publication year—not measured thresholds for particular apps.

On a Mac, Apple directs users to System Information and the Upgradeable Memory information when available. Some computers do not offer user-upgradeable RAM. A compatible upgrade can help with a memory-limited workload, but it will not target an app-specific problem or guarantee a performance improvement.
