Why Does Chrome Open Multiple Processes?

Google Chrome is a widely used browser known for its speed and efficiency. However, users may encounter situations where multiple Chrome processes run simultaneously, consuming excessive system resources. This behavior stems from Chrome’s default setting, which launches a separate process for each tab, extension, and subframe. This design aims to prevent data loss in case of a tab crash.

How to Stop Multiple Chrome Processes

To address this issue and reduce the number of Chrome processes, several methods can be employed:

1. Modify Chrome.exe Target:

This method involves modifying the target path of the Chrome shortcut to include the “–process-per-site” command. This instructs Chrome to run a single process for each website, minimizing the number of active processes.

  1. Right-click the Chrome shortcut on the desktop and select “Properties.”
  2. In the “Target” field, add ” –process-per-site” to the end of the existing path, ensuring a space before the command.
  3. Click “OK” to save the changes.

Note: Some users have reported limited success with this method.

2. End Tasks Manually via Chrome Task Manager:

The Chrome Task Manager provides a detailed view of all running Chrome processes. It allows users to identify and terminate specific tasks that are consuming excessive resources.

  1. Press “Shift+Esc” to launch the Chrome Task Manager.
  2. Select the task you want to terminate and click “End Process.”

3. Close Idle Tabs:

Leaving idle tabs open can contribute to the proliferation of Chrome processes, as each tab runs its own process. Regularly closing idle tabs can help reduce the number of active processes.

4. Remove Unwanted Extensions:

Extensions can also contribute to the creation of separate Chrome processes. Regularly reviewing and removing unwanted extensions can help minimize the number of active processes.

5. End Apps Running in the Background:

Chrome continues to run web apps and extensions in the background even after closing the browser. Disabling this feature can help reduce the number of active processes.

  1. Open Chrome settings.
  2. Click “Advanced” in the left panel.
  3. Under “System,” uncheck the box labeled “Continue running background apps when Google Chrome is closed.”


By implementing these methods, users can effectively reduce the number of Chrome processes running simultaneously, thereby optimizing system resource utilization and improving overall performance.


Why does Chrome open multiple processes?

Chrome opens multiple processes to enhance stability and prevent data loss. Each tab, extension, and subframe runs in its own process, isolating them from each other. If one process crashes, it won’t affect the others, and your browsing session remains uninterrupted.

How can I reduce the number of Chrome processes?

To reduce the number of Chrome processes, you can:

  • Modify the Chrome.exe target to include the “–process-per-site” command.
  • End tasks manually via the Chrome Task Manager.
  • Close idle tabs.
  • Remove unwanted extensions.
  • End apps running in the background.

Is it better to have multiple Chrome processes or a single process?

Having multiple Chrome processes can improve stability and prevent data loss, but it can also consume more system resources. If you have a powerful computer and prioritize stability, multiple processes may be preferable. If you have a limited amount of system resources or experience performance issues, running Chrome with a single process may be more suitable.

What are the advantages of using the “–process-per-site” command?

The “–process-per-site” command reduces the number of Chrome processes by running each website in a separate process. This can improve performance and reduce memory usage, especially if you frequently visit websites with heavy content or scripts.

What are the potential drawbacks of using the “–process-per-site” command?

The “–process-per-site” command may not be compatible with all websites or extensions. Additionally, it can increase the time it takes for Chrome to start up and may result in higher memory usage in certain scenarios.

Can I disable the Chrome Task Manager?

It is not recommended to disable the Chrome Task Manager. The Chrome Task Manager is a valuable tool for monitoring and managing Chrome processes. It allows you to identify and terminate unresponsive or resource-intensive tasks, improving Chrome’s overall performance and stability.
