How to Block Websites in Google Chrome

Managing the websites you can access in Google Chrome can make browsing more productive and help create a safer online environment for children. Whether you want to avoid distracting websites during work, limit unnecessary screen time, or manage your child’s internet access, several tools can help you restrict specific websites.

Google Chrome does not offer a universal built-in setting for blocking any website. However, you can use browser extensions, Google Family Link, Windows system settings, or network-level filtering to achieve a similar result.

The best approach depends on your needs, the devices you use, and how much control you want over website access. Below, we explain four practical methods and how to set them up.

Which Website-Blocking Method Should You Choose?

Before changing any settings, consider where you want the restrictions to apply.

• Chrome extensions: Suitable for blocking distracting websites while browsing.
• Google Family Link: Designed to help parents manage their children’s online experiences.
• Windows Hosts file: An option for restricting certain domains on a Windows computer.
• Router or DNS filtering: Useful for applying website restrictions across multiple devices on a home network.

Each option works differently, so understanding its limitations can help you choose the right solution.

1. Use a Chrome Extension to Restrict Websites

If you want a quick way to prevent yourself from opening particular websites, a Chrome extension is often a convenient starting point. Tools such as BlockSite provide website-blocking features and may include additional options, such as schedules and focus settings.

How to Install and Configure an Extension

Follow these steps to get started:

1. Open Google Chrome on your computer.
2. Visit the Chrome Web Store.
3. Search for a website-blocking extension, such as BlockSite.
4. Review its available features, user feedback, requested permissions, and privacy policy.
5. Open the extension’s listing and select Add to Chrome.
6. Confirm the installation when prompted.
7. Open the extension from the Extensions menu near the address bar.
8. Follow its instructions to add the websites you want to block.

After setup, the extension can restrict access to the websites included in its block list, according to its features and permissions.

For example, you could block social media websites during working hours or restrict access to entertainment sites while studying. If the extension supports scheduling, you may also be able to set specific times when those restrictions apply.

Things to consider: Chrome extensions are developed by third parties. Their privacy practices, features, and reliability can differ. An extension may also be disabled or removed by someone who has permission to manage the browser, so it should not be considered tamper-proof.

2. Manage Children’s Website Access With Google Family Link

Parents who want to manage their children’s browsing activity can explore Google Family Link. This service provides parental supervision tools for supported Google accounts and devices.

Depending on the account and available settings, parents may be able to restrict certain websites or limit browsing to approved sites in Google Chrome.

Steps to Manage Chrome Website Restrictions

1. Open the Google Family Link app on your phone.
2. Select the child’s supervised account.
3. Navigate to the controls or settings for your child’s online activity.
4. Find the settings for Google Chrome or web browsing.
5. Review the available options for managing website access.
6. Select the appropriate restriction, such as blocking specific websites or allowing only approved sites, if supported.
7. Add the relevant website addresses and save your changes.

The exact menu names and available controls can vary depending on the child’s account, device, and the current version of Family Link.

For younger children, an approved-sites approach may provide more control over which websites they can visit. For other situations, blocking selected domains may be more practical.

Important Limitations of Family Link

Website restrictions are not necessarily universal across every browser, device, or network. Some controls apply specifically to Chrome when the child is signed in with the supervised account.

Before relying on a particular restriction, check the current instructions in Google Family Link Help.

Parents should also remember that technical restrictions work best alongside age-appropriate conversations about online safety, privacy, and responsible internet use.

3. Block Websites Using the Windows Hosts File

Windows includes a system file called the Hosts file, which helps the operating system associate domain names with IP addresses. By editing this file, you can redirect certain domain names locally and sometimes prevent them from loading normally.

Unlike a Chrome extension, this method can affect multiple browsers on the same Windows computer. However, it requires administrator access and does not provide comprehensive website filtering.

Step 1: Open Notepad With Administrator Permissions

Open the Windows Start menu and search for Notepad.

Right-click the application and choose Run as administrator. Approve the permission prompt if Windows displays one.

Administrator access is necessary to save changes to the system Hosts file.

Step 2: Locate the Hosts File

In Notepad, select File > Open and navigate to the following path:

C:\Windows\System32\drivers\etc\hosts

In the file selection window, change the file-type filter to All files so that the Hosts file becomes visible.

Select the file and open it.

Step 3: Add the Domain You Want to Restrict

Move to the end of the file and add an entry for the domain you want to target.

For example, the following entry redirects example.com to the local computer:

127.0.0.1 example.com

To include the www version as well, add another line:

127.0.0.1 www.example.com

These are demonstration domains. Replace them with the actual domain names you want to restrict.

Be aware that websites may use several subdomains or alternative addresses. Adding the main domain does not automatically block every related address, and redirecting a domain to the local computer may not produce the same result in every browser or network configuration.

Step 4: Save and Test Your Changes

Save the file, then open Chrome and check whether the selected domain is restricted.

If the change does not take effect immediately, you may need to restart the browser or refresh the Windows DNS cache. You can do this from an administrator Command Prompt using:

ipconfig /flushdns

This command clears the Windows DNS resolver cache, but it does not guarantee that the website will be blocked.

Is the Hosts File Method Right for You?

This approach can be useful when you want to experiment with basic domain restrictions without installing a browser extension. However, it requires careful editing and is not a complete parental-control or security solution.

Incorrect changes can interfere with normal network access. Keep a backup of the original file before making modifications, and remove any entries you no longer need.

4. Block Websites on Multiple Devices With Router or DNS Filtering

If you want to restrict access on more than one device, network-level filtering may be a better fit. Depending on the configuration, router settings or a DNS filtering service can apply restrictions to computers, phones, tablets, and other devices connected to your home network.

This can be particularly useful for households that want a consistent set of browsing rules.

Option A: Configure Your Router’s Parental Controls

Many home routers include features for parental controls, website filtering, or internet access management. The exact options depend on the router model and its software.

To check whether your router supports website restrictions:

1. Open your router’s administration page or official companion app.
2. Sign in with your administrator credentials.
3. Look for a section called Parental Controls, Website Filtering, or Access Control.
4. Check whether the available settings let you block specific domains or categories of websites.
5. Add the domains you want to restrict.
6. Save the settings and test the result on a connected device.

Some routers also allow restrictions to be applied to individual devices or during selected hours.

If you cannot locate these settings, consult the router manufacturer’s official documentation. Not every router supports domain-based blocking, and the available features may depend on firmware updates or subscription services.

Option B: Use a DNS Filtering Service

A DNS filtering service can apply rules when devices attempt to look up website domain names. Depending on the provider, you may be able to block individual domains or filter groups of websites.

There are two common ways to configure this type of service:

• Router-level configuration: Applies the selected DNS settings to devices that use the router’s network configuration.
• Device-level configuration: Applies the settings only to the computer or other device where they are configured.

Router-level filtering can be convenient when you want to manage several household devices from one place. Device-level filtering may be more suitable when you only want to restrict browsing on a particular computer.

However, DNS filtering has limitations. Restrictions may not apply when a device switches to mobile data or another Wi-Fi network. Some browser privacy features, VPNs, or alternative DNS configurations can also bypass certain network rules.

For stronger protection, review the filtering service’s documentation and check whether its supported controls match your requirements.

Tips for Choosing the Right Website-Blocking Solution

The most suitable method depends on your priorities. Use the following comparison as a starting point.

Method	Best suited for	Main limitation
Chrome extension	Personal productivity and focus	May be disabled or removed
Google Family Link	Parental supervision	Depends on supported accounts and settings
Windows Hosts file	Basic domain restrictions on a PC	Requires manual editing and has limited coverage
Router or DNS filtering	Managing access across a home network	May not apply outside the configured network

Before setting up any restrictions, consider these additional points:

• Check the scope: Decide whether you need to block a website in Chrome only, across all browsers on one computer, or across an entire network.
• Review privacy: Choose extensions and filtering services with clear privacy policies and appropriate permissions.
• Test the result: Confirm that the intended website is restricted without interfering with unrelated websites.
• Understand the limitations: No single method guarantees that a website will be inaccessible through every browser, device, or network.
• Keep settings updated: Review your configuration occasionally to make sure it still meets your needs.
