The fastest way to block a website on Android

You can block a website on Android using your phone's built-in parental controls, a third-party app, or your Wi-Fi router settings. The method you choose depends on whether you want to block sites on your device only, across your whole network, or for another person's account.

The simplest approach for most people is installing a free blocking app like Freedom, AppBlock, or BlockSite directly on your phone. These apps let you add websites to a blocklist and prevent them from opening in any browser. If you want to block sites for a child or teenager, Android's built-in Family Link feature works without installing anything extra.

If you want to block sites across all devices on your home network — phones, tablets, computers — you can configure your Wi-Fi router instead. This method blocks the site before it even reaches your device, which is harder to bypass.

Key Takeaways

  • Third-party blocking apps like BlockSite and Freedom work on any Android phone and let you block websites in seconds without changing system settings.
  • Google Family Link is built into Android and lets you block sites for a child's account without installing a separate app.
  • Router-level blocking affects every device on your Wi-Fi network but requires you to log into your router's admin panel.
  • Blocking apps can be bypassed by switching to a different browser or using mobile data, so they work best for self-discipline rather than strict parental control.
  • Some blocking apps let you set time limits so sites are only blocked during certain hours, like work time or bedtime.

Using a blocking app on your Android phone

Installing a third-party blocking app is the fastest method and works on any Android phone. Open Google Play Store, search for "BlockSite" or "Freedom", and tap Install. Both apps are free and do not require a subscription to block websites, though they offer paid features for more control.

After installation, open the app and tap the button to add a new blocked site. Type the website URL — for example, reddit.com or youtube.com — and confirm. The app will block that site in your default browser immediately. If you use multiple browsers like Chrome and Firefox, you may need to configure the app in each one, or switch to using only one browser.

Most blocking apps let you set a PIN or password so you cannot turn off the block without entering it. This prevents you from simply uninstalling the app or removing the site from the blocklist in a moment of weakness. Set a PIN you will not remember easily, or ask someone else to create one and not tell you.

The main limitation of blocking apps is that they do not block sites on mobile data — only on Wi-Fi. If you want to block a site everywhere, you need to use your router settings or a different method.

Setting up Family Link to block sites for a child

If you are blocking websites for a child or teenager, Google Family Link is built into Android and requires no separate app. On your own phone, open Google Play Store and search for "Family Link". Install it and sign in with your Google account.

Tap "Create a supervised account" and follow the steps to set up a child's account. You will need their email address or create one for them. Once the account is created, go to the Family Link app on your phone, tap the child's name, then tap "Controls on Google Play" or "App settings" depending on your Android version.

Look for the option labeled "Manage sites" or "Restricted content". Add the websites you want to block by typing the URL. Family Link blocks these sites across Chrome and the default browser on the child's device. The child cannot remove the block without your PIN.

Family Link also lets you set screen time limits, see which apps they use, and lock their device at bedtime. These controls work only on the child's device, not across your home network.

Blocking websites through your Wi-Fi router

Blocking at the router level affects every device connected to your Wi-Fi — phones, tablets, computers — without installing anything on each device. This method is harder to bypass because the block happens before data reaches your phone.

Open a web browser on any device connected to your Wi-Fi and type your router's IP address into the address bar. The most common addresses are 192.168.1.1 or 192.168.0.1. If neither works, check the sticker on the back of your router or the manual that came with it.

Log in using your router's admin username and password. If you have never changed these, they are usually printed on the router itself — often "admin" and "admin", or "admin" and the router's serial number. Once logged in, look for a section called "Parental Controls", "Content Filtering", "Access Control", or "Website Blocking". The exact name varies by router brand.

Add the website URL to the blocklist and save your changes. The block takes effect immediately on all devices. If you forget the admin password, you can reset the router to factory settings by holding the reset button for 10 seconds, but this erases all your custom settings.

Blocking sites in Chrome's built-in tools

Chrome has a built-in feature called Supervised Users that blocks certain categories of content, though it does not let you block specific websites by URL. This works best if you want to block adult content broadly rather than one particular site.

Open Chrome and tap the three-dot menu in the top right. Tap "Settings", then "Parental controls". Turn on "Supervised browsing" and set a PIN. Chrome will then block sites it categorizes as adult content, violence, or other restricted categories.

This method is less precise than using a blocking app or router settings because you cannot choose which specific sites to block — you can only choose content categories. If you need to block one particular website, use a blocking app instead.

What to do if someone bypasses the block

Blocking apps can be bypassed by switching to a different browser, using mobile data instead of Wi-Fi, or uninstalling the app. If you set a PIN on the blocking app, they cannot uninstall it without the PIN, but they can still switch browsers or use data.

Router-level blocking is harder to bypass because it blocks the site for all devices and all browsers. However, someone can bypass it by using a VPN app or connecting to a different Wi-Fi network outside your home.

If you are blocking sites for a child, the most effective approach is combining methods: use Family Link on their device plus router-level blocking on your home network. This closes most escape routes. For your own use, a blocking app with a strong PIN works well because the goal is self-discipline rather than preventing someone else from accessing something.

Unblocking a website when you need to

If you blocked a site using a third-party app and set a PIN, you will need to enter that PIN to remove it from the blocklist. Open the blocking app, find the site in your blocked list, and tap the option to remove or unblock it. Enter your PIN when prompted.

If you blocked a site at the router level, log back into your router's admin panel using the same IP address and login credentials. Find the blocked sites list and remove the URL. Save your changes and the block will lift immediately.

If you are unblocking a site for a child using Family Link, open the Family Link app on your phone, tap the child's name, go to "Manage sites", and remove the URL from the blocklist. The child will see the change on their device within a few minutes.

Frequently Asked Questions

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

Yes, if you block it at your Wi-Fi router level. You log into your router's admin panel and add the site to a blocklist there. This blocks the site for all devices on your network without installing anything on your phone. However, if you want to block a site only on your phone, you will need a blocking app or use Family Link.

Will blocking apps work if someone uses a VPN?

No. A VPN app routes your traffic through a different server, which bypasses most blocking apps. Router-level blocking also does not work with a VPN because the VPN encrypts your traffic before it reaches the router. If preventing VPN use is important, you would need to configure your router to block VPN traffic, which is more advanced.

Can I block a website on Android for just certain hours of the day?

Yes, some blocking apps like Freedom and AppBlock let you set schedules so a site is blocked only during work hours or bedtime, then unblocked automatically at other times. Family Link also lets you set screen time limits by hour. Check the app's settings to see if scheduling is available.

What if I block a site but still see it in search results?

Blocking apps block the website itself, not search results that link to it. If you tap a search result for a blocked site, the blocker will prevent the page from loading. The search result will still appear in Google or your search engine, but you cannot visit it.

Does blocking a website use data or battery?

Blocking apps use very little data or battery because they simply prevent your browser from loading certain URLs. Router-level blocking uses no data or battery on your phone at all because the blocking happens on the router itself, not on your device.
