You can remove the Side panel button from Google Chrome by launching the browser with a specific command-line flag that disables the feature entirely. This method works across Windows, macOS, and Linux by modifying how Chrome starts, effectively hiding the button from the toolbar without requiring complex extensions or registry edits.
Understanding the Side Panel Feature
The Side panel is a relatively new interface element in modern versions of Google Chrome. It appears as an icon on the right side of the address bar, typically resembling a rectangle or a set of lines. When clicked, it opens a vertical pane that hosts various tools such as reading list, translate, images, and shopping assistants. While this feature adds functionality for many users, others find it cluttered or unnecessary, preferring a cleaner toolbar layout.
Google has not provided a simple toggle switch in the standard settings menu to hide this button permanently. This absence often frustrates users who want to reclaim that screen real estate. Consequently, the most reliable workaround involves starting Chrome with a disable flag. This approach tells the browser engine to ignore the code responsible for rendering the Side panel UI components.
Why Standard Settings Are Insufficient
Many users attempt to find a "Hide Side Panel" option under chrome://settings. However, Chrome currently lacks a native preference for this specific action. You might see options to manage which apps appear in the panel, but you cannot remove the launcher icon itself through the graphical user interface. This limitation is why command-line arguments become necessary for a permanent solution.
Step-by-Step Guide to Disable via Command Line
To apply this change, you must modify the shortcut you use to launch Chrome. The process differs slightly depending on your operating system, but the core principle remains the same: add a parameter to the target path.
For Windows Users
- Locate your Google Chrome shortcut. This is usually on your desktop or in your Start Menu.
- Right-click the shortcut and select Properties.
- In the Properties window, find the Target field. It will look something like
"C:\Program Files\Google\Chrome\Application\chrome.exe". - Add a space at the end of the existing text, then type
--disable-features=SidePanel. - The final string should resemble:
"C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-features=SidePanel. - Click Apply and then OK.
- Close any running instances of Chrome and open it using this modified shortcut.
If you are using Chrome Portable or a different installation directory, ensure you copy the correct path from the properties window before adding the flag.
For macOS Users
macOS does not allow direct editing of application shortcuts in the same way. Instead, you need to create a shell script or use a third-party tool like FastScripts. A common method involves creating a terminal command:
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --disable-features=SidePanelYou can save this as an executable script and assign it to a keyboard shortcut or place it in your Dock. Alternatively, some users prefer using a utility like AppTrap or modifying the application bundle directly, though the latter is more complex and may break with updates.
For Linux Users
Linux users can edit their desktop entry files. Open a terminal and navigate to ~/.local/share/applications or /usr/share/applications. Find the file named google-chrome.desktop. Edit the line starting with Exec= and append --disable-features=SidePanel to the end of the command.
Verifying the Change
After launching Chrome with the flag, check the toolbar. The Side panel button should be completely gone. If you still see it, ensure that no other flags are conflicting and that you restarted all Chrome processes. You can verify the active features by navigating to chrome://flags, though the Side Panel feature itself may not appear in the list if it is successfully disabled at startup.
Note that this setting applies only to the profile launched via the modified shortcut. If you have multiple Chrome profiles, you may need to create separate shortcuts for each, or accept that the change applies globally if you always use the same launcher.
Reverting the Change
To restore the Side panel, simply return to the shortcut properties and delete the --disable-features=SidePanel portion from the Target field. Save the changes and restart Chrome. The button will reappear immediately upon next launch.
Alternative Approaches
If you prefer not to modify shortcuts, you might consider using a custom CSS extension like Stylus. However, injecting CSS to hide toolbar elements is often unstable and can break during Chrome updates. The command-line flag is a native solution supported by Chromium, making it more robust than cosmetic fixes.
Another alternative is to use a different browser if the Side panel is a dealbreaker. Browsers like Firefox or Edge offer different default layouts, though Edge also includes a sidebar feature. For those committed to Chrome, the flag method remains the most effective technical workaround.
Some users report issues with other features when disabling certain UI components. While SidePanel is generally isolated, broad feature flags can sometimes impact related functionalities. If you encounter unexpected behavior, try removing the flag temporarily to diagnose the cause.

Frequently Asked Questions
Does this update affect my bookmarks?
No, disabling the Side panel feature does not delete or alter your bookmarks, history, or saved passwords. It only hides the user interface element. Your data remains stored locally and synced to your Google account as usual.
Will this fix persist after Chrome updates?
Yes, the command-line flag is part of your shortcut configuration, not the browser installation itself. When Chrome updates automatically, it replaces the binary files but preserves your shortcut targets. You will not need to reapply the flag unless you manually reset the shortcut.
Can I hide the button for just one profile?
The flag affects the entire browser instance. If you run multiple profiles, they all share the same launcher settings. To have different behaviors for different profiles, you would need to create separate shortcuts with different target arguments, though this is rarely necessary for most users.
Is there a risk of security vulnerabilities?
Using the --disable-features flag is safe and is a standard practice for developers and advanced users. It does not expose your system to malware or security risks. It simply instructs the browser to skip loading specific code modules during initialization.
What if the button still appears?
If the button remains visible, check that you added the flag correctly with a preceding space. Also, ensure that no other extensions are interfering. Try launching Chrome in Incognito mode to rule out extension conflicts, although the flag should work regardless of extensions.
