The simplest way to block a site in Chrome on Android

Chrome on Android does not have a built-in feature to block individual websites. If you want to prevent access to a specific site, you have three real options: use your phone's parental controls, install a third-party app that filters web traffic, or use your router's settings to block sites across all devices on your network.

The method you choose depends on who you are trying to block the site from. If you are blocking sites from yourself, a router-level block or a filtering app works. If you are blocking sites from someone else — a child, for example — Android's built-in parental controls are the most reliable because they are harder to bypass.

Key Takeaways

  • Chrome itself has no site-blocking feature, but Android's parental controls can restrict access to websites across all apps on a device.
  • Third-party filtering apps like Freedom, Cold Turkey, or OpenDNS can block sites in Chrome and other browsers, though they require device administrator access.
  • Router-level blocking through your WiFi settings prevents access to a site on any device connected to that network, including phones and computers.
  • Parental controls are the hardest to disable without the parent's PIN, making them the best choice if you are blocking sites from someone else.

Using Android's built-in parental controls to block sites

Android has a parental controls feature called Family Link that lets you restrict access to websites. To set this up, you need a Google account and the ability to install the Family Link app on both your own phone and the device you want to restrict.

Open the Family Link app on your own device, select the child's account, tap Controls on Google Play, then scroll down to Approved apps or Restricted content. From there you can block specific apps, but for websites, you will need to use Chrome's settings within Family Link. Go to Chrome in the Family Link menu, then Manage SafeSearch and site restrictions. You can block individual sites by entering their web address.

The advantage of Family Link is that it requires a PIN to disable, so someone cannot straightforward turn it off. The disadvantage is that it only works if you have set up a supervised Google account on the device — it does not work on a regular personal account.

Installing a filtering app to block sites in Chrome

Apps like Freedom, Cold Turkey Blocker, and OpenDNS Home run in the background and block websites across Chrome and other browsers. These apps work by filtering your internet traffic before it reaches your phone.

To install one, go to the Google Play Store, search for the app name, and tap Install. After installation, the app will ask for device administrator access — this is a permission that lets the app control certain phone settings. Grant this permission, then open the app and add the websites you want to block to a blocklist.

The trade-off is that these apps consume battery and data because they monitor all traffic. They also vary in how straightforward they are to disable — some require a password to turn off, others do not. If you are blocking sites from yourself, this is less important. If you are blocking sites from someone else, check the app's settings to see whether it requires a password to disable.

Blocking sites through your WiFi router

Your WiFi router has built-in controls that can block websites for any device connected to it. This method works across Chrome, Safari, Firefox, and any other app that uses the internet.

Log into your router's settings by opening a web browser on a computer or phone connected to the same WiFi, then typing your router's IP address (usually 192.168.1.1 or 192.168.0.1) into the address bar. You will be asked for a username and password — check your router's manual or the sticker on the back of the device if you do not know these.

Once logged in, look for a section called Parental Controls, Access Control, or Website Filtering. The exact name varies by router brand. Enter the website address you want to block, save the settings, and the site will be inaccessible on any device using that WiFi network.

The advantage is that this blocks the site everywhere on your network, not just in Chrome. The disadvantage is that it only works on your home WiFi — someone can still access the site on mobile data or a different network.

Why Chrome itself does not have a built-in blocker

Chrome on desktop has an extension system that lets you install third-party blockers like uBlock Origin or LeechBlock. Chrome on Android does not support extensions, which is why you cannot straightforward add a blocking extension the way you would on a computer.

Google's reasoning is that extensions on mobile could slow down the browser and create security risks. Instead, Google built parental controls into Android itself through Family Link, which is why that is the most integrated option for blocking sites on Android phones.

What happens when you try to visit a blocked site

If a site is blocked through Family Link, you will see a message saying the site is restricted and cannot be accessed. If it is blocked through a filtering app, the app will typically show a block page with the app's logo. If it is blocked through your router, you will usually see an error message saying the page cannot be reached.

In all three cases, the block happens before Chrome loads the page, so the site cannot run any code on your phone. This is different from straightforward closing a tab — the site is not accessible at all.

Frequently Asked Questions

Can someone disable a blocked site if they have the phone?

It depends on the method. Family Link requires a PIN to disable, so it is hard to bypass. Filtering apps vary — some require a password, others do not. Router blocking cannot be disabled from the phone itself, only from the router settings. If someone has access to your router's admin password, they can disable it.

Will blocking a site in Chrome also block it in other apps?

No. Chrome blocking only affects Chrome. Family Link blocks sites across all browsers and apps. Filtering apps block sites across all browsers but not necessarily in other apps. Router blocking works everywhere on that network.

Does blocking a site use more data or battery?

Family Link and router blocking have no noticeable impact. Filtering apps do use extra battery and data because they monitor all traffic. The impact is usually small — a few percent of battery per day — but it is measurable.

What if the site uses a different web address than the one I blocked?

You may need to block multiple versions. For example, blocking example.com will not block www.example.com or example.co.uk. Most blocking tools let you add multiple addresses, and some support wildcard blocking (blocking all subdomains at once). Check your blocking tool's documentation for the exact syntax.

Can I block a site only during certain hours?

Family Link has scheduling options — you can set times when the device is restricted. Some filtering apps also offer scheduling. Router blocking is always on. If you need time-based blocking, Family Link or a filtering app with scheduling is your best option.
