The simplest way to block a website on Android

The fastest method is to use your phone's built-in Safe Browsing feature in Google Chrome, which blocks sites you add to a personal list. Open Chrome, visit the website you want to block, tap the three-dot menu in the top right, scroll down to "Settings," then tap "Site settings" and toggle on "Block." The site will not load the next time you try to visit it from Chrome.

If you use a different browser like Firefox or Samsung Internet, each has its own blocking method — Firefox lets you block sites through its settings menu, while Samsung Internet uses a similar three-dot menu approach. The downside of browser-level blocking is that it only works inside that specific app; someone could still reach the site by switching browsers or using a search engine's direct link.

For stronger blocking that works across all apps and browsers on your phone, you will need to use a third-party app or adjust your phone's network settings. These methods take a few more steps but prevent the blocked site from loading no matter how someone tries to reach it.

Key Takeaways

  • Chrome's built-in blocking feature is the quickest option and works only within Chrome itself.
  • Third-party blocking apps like AppBlock or Freedom can block websites across all browsers and apps on your device.
  • DNS-level blocking through your phone's network settings prevents access to blocked sites from any app, but requires manual entry of IP addresses.
  • Parental control apps like Google Family Link offer website blocking as part of a larger monitoring system, useful if you are managing a child's device.
  • Blocking a website on your phone does not prevent access from other devices on your home network.

Using a third-party blocking app for stronger control

Apps like AppBlock, Freedom, and BlockSite let you block websites across all browsers and apps on your Android device. read one from the Google Play Store, open it, and add the website URL to your blocked list. These apps work by intercepting network requests before they reach any browser, so the site cannot load regardless of which app you use to try to reach it.

Most of these apps also let you set time-based blocking — for example, blocking social media sites during work hours but allowing them in the evening. Some require you to grant device administrator access, which gives the app deeper control over your phone's settings. Read the permissions screen carefully before granting this access, as it means the app can prevent you from uninstalling it without removing its admin status first.

The trade-off is that third-party apps consume battery and memory, and some require a paid subscription for advanced features. Free versions usually cover basic website blocking, which is enough for most people.

Blocking websites through your phone's DNS settings

A DNS (Domain Name System) is the service that translates website names like "example.com" into the numerical addresses your phone uses to connect. By changing your phone's DNS provider to one that blocks certain sites, you can prevent access without installing an app. Go to Settings, tap "Connections" or "Network," find "Wi-Fi," hold down your connected network, tap "Modify," and change the DNS servers to those of a blocking service like Cloudflare's 1.1.1.2 or OpenDNS.

This method works across all apps and browsers on your phone, and it does not drain your battery. The downside is that DNS blocking is less precise — you cannot block individual pages, only entire domains, and some blocking services are designed for families rather than personal use. Also, DNS blocking only works when you are connected to Wi-Fi; it does not affect websites visited over mobile data unless you change your mobile network's DNS settings, which most carriers do not allow.

If you want to block a site on mobile data as well, you would need to use a VPN app that supports blocking, which adds another layer of complexity.

Setting up parental controls to block websites

If you are managing a child's Android device, Google Family Link is built into Android and does not require a separate app purchase. The parent creates a Google account, adds the child's device, and can then block specific websites and app categories from a parent dashboard. Open Family Link on your phone, select the child's device, tap "Controls on Google Play," and add sites to the blocked list.

Family Link also shows screen time, app usage, and location, making it useful if you want oversight beyond just website blocking. The child cannot remove Family Link without the parent's password, so the blocking cannot be easily bypassed. However, Family Link only works on devices where the child has a supervised Google account; it does not work on devices with a regular adult account.

Third-party parental control apps like Bark, Net Nanny, and Qustodio offer more detailed blocking and monitoring but usually cost money and require more setup than Family Link.

Why blocking might not work and what to do about it

If you block a website but it still loads, the most common reason is that you are using a different browser than the one where you set the block. Chrome blocking does not affect Firefox, and vice versa. Check which browser you used to set the block and try again from that same browser.

If you are using a third-party app and the site still loads, the app may not have permission to intercept network traffic. Go to Settings, tap "Apps," find the blocking app, and check that it has permission to access "Device admin" or "VPN" depending on how the app works. Some blocking apps also require you to disable your phone's automatic proxy settings, which can interfere with the block.

If you are using DNS blocking and a site still loads, try clearing your phone's DNS cache by going to Settings, Apps, and force-stopping your browser, then restarting it. DNS changes can take a few minutes to take effect across all apps.

Blocking websites on shared or work devices

If the Android device is owned by your employer or school, they may have already installed a Mobile Device Management (MDM) app that controls what you can access. These apps appear in your settings as "Device admin" or "Work profile" and cannot be removed without the organization's permission. If you see one, contact your IT department before trying to block or unblock websites, as they may have policies about what you can change.

On a shared family device, blocking a website affects everyone who uses that phone. If you want to block a site only for yourself, use a browser-specific method like Chrome's built-in blocking, or ask the device owner to set up separate user accounts if your Android version supports them. Most newer Android phones allow multiple user profiles, each with its own apps and settings.

Frequently Asked Questions

Can someone unblock a website I blocked on my Android phone?

If you use Chrome's built-in blocking, anyone with access to your phone can unblock the site by opening Chrome settings and removing it from the blocked list. If you use a third-party app with a password or PIN, they cannot unblock it without that password. If you use DNS blocking, they would need to change your Wi-Fi settings, which requires access to your phone's settings menu.

Will blocking a website on my phone block it on my home Wi-Fi for other devices?

No. Blocking on your individual phone only affects that device. To block a website for all devices on your home network, you would need to change the blocking settings in your Wi-Fi router itself, which is a different process and depends on your router model.

Does blocking a website use data or battery?

Browser-based blocking uses almost no extra resources. Third-party apps use a small amount of battery and data because they run in the background. DNS blocking uses almost no battery or data. VPN-based blocking apps use more battery because they maintain a constant connection.

Can I block a website on Android without installing an app?

Yes. You can use Chrome's built-in blocking feature, Firefox's blocking feature, or change your phone's DNS settings through the Wi-Fi menu. All three methods work without downloading a separate app.

What happens if I block a website by mistake?

You can unblock it the same way you blocked it. In Chrome, open the site's settings and toggle off the block. In a third-party app, find the site in your blocked list and delete it. In DNS settings, change your DNS servers back to your carrier's default or to a non-blocking service like 8.8.8.8.
