Chrome Task Manager shows what is happening inside Chrome, broken down by tab, extension, and browser process. Instead of guessing which tab is slowing everything down, you can sort by memory or CPU and close only the item causing trouble.
Does this affect you?
Use this for Chrome on Windows, Mac, or Chromebook when Chrome feels sluggish, the fan spins up, or you want to identify the exact tab or extension using too much CPU, memory, or network activity.
Open Chrome Task Manager
Chrome Task Manager is separate from Windows Task Manager and macOS Activity Monitor.
- Click the three-dot menu in Chrome.
- Open More tools.
- Click Task Manager. On Windows and Chromebook, Shift+Esc opens it directly.
- Review the list of tabs, extensions, and background processes.
- Click Memory or CPU to sort by usage.
- Select the problem item and click End process.
Ending one item closes that tab or extension process while leaving the rest of Chrome running.
Add more columns
Extra columns can help when you need more detail.
- Open Chrome Task Manager.
- Right-click the header row where Memory and CPU appear.
- Enable columns such as Process ID, GPU Memory, or Image Cache.
- Use Process ID if you need to match a Chrome process in the operating system task manager.
More control
Do not worry about core rows first
Browser and GPU Process are core Chrome pieces and may not be endable. Focus on tabs and extensions with high or steadily climbing usage.
Heavy tabs are sometimes normal
Video calls, spreadsheets, maps, and large web apps can use hundreds of megabytes. A simple page that keeps climbing, however, may have a memory leak and should be reloaded or closed.
Watch extensions with background CPU
If an extension uses CPU while idle, disable it from chrome://extensions and check whether Chrome becomes smoother.
Check the whole computer too
Chrome Task Manager only covers Chrome. If the entire computer is slow, also check Windows Task Manager or macOS Activity Monitor for other apps consuming resources.
