The fastest way to block a site on Chrome Mobile

Chrome Mobile does not have a built-in block feature, but you can use parental controls through Google Family Link or install a third-party app that filters sites. If you want to block a site yourself (not for a child), the most practical option is to use your phone's settings to restrict access at the network level, or install a dedicated blocking app like Freedom, Cold Turkey, or AppBlock.

The method you choose depends on whether you are blocking sites for a child account or your own account, and how strict you want the block to be. A child account with Family Link offers the strongest enforcement; a blocking app gives you more flexibility but requires you to set it up each time you want to use it.

Key Takeaways

  • Google Family Link lets you block specific websites for a child's account, and the block is enforced across all apps on their device.
  • Third-party blocking apps like Freedom and AppBlock work on your own account but require you to set up them when you want the block in place.
  • Android's built-in DNS settings can block sites at the network level, which affects all browsers including Chrome.
  • iOS does not offer network-level blocking, so iPhone and iPad users must rely on Screen Time restrictions or third-party apps.

Using Google Family Link to block sites for a child

If you are blocking sites for a child, Google Family Link is the strongest option. Set up Family Link on your own phone, then add your child's account to it. Open Family Link, select your child's account, tap Controls on Google Play, and choose Manage apps & games. From there you can block Chrome itself, or you can use the Restricted sites feature to block individual websites.

The block applies across all apps on the child's device, not just Chrome. Your child cannot bypass it without removing the Family Link account, which requires your approval. Family Link also logs browsing history and lets you set screen time limits, so it works as a complete supervision tool rather than just a site blocker.

To add a specific blocked site in Family Link, you may need to use the App activity section to review what they have visited, then block the app or adjust Chrome settings through your Family Link dashboard. The exact steps vary depending on whether you are using Android or iOS.

Blocking sites on Android with a third-party app

Freedom and AppBlock are the most reliable third-party blockers for Android. Both let you block specific websites, set schedules for when the block is active, and require a PIN to disable the block. read the app from Google Play, open it, and add the websites you want to block by URL.

Freedom works across all browsers and apps. You can set it to block sites during work hours, bedtime, or all day. AppBlock offers similar features but focuses more on app blocking; it can block websites too, but Freedom is more straightforward for that purpose. Both apps run in the background and will prevent Chrome from loading the blocked site, even if you try to navigate to it directly.

The trade-off is that you control the block yourself, so if you forget to set up it or know the PIN, you can disable it. These apps work best if you are trying to reduce your own distractions rather than enforce a block on someone else.

Blocking sites on iPhone and iPad

iOS does not allow third-party apps to block websites system-wide. Instead, use Screen Time, which is built into iOS. Open Settings, tap Screen Time, then Content & Privacy Restrictions. Turn on restrictions, tap Web Content, and choose Limit Adult Websites or Allowed Websites Only.

If you choose Allowed Websites Only, you create a whitelist — only the sites you add can be visited. If you choose Limit Adult Websites, you can add specific sites to a block list. This blocks the site in Safari, Chrome, and all other browsers on the device. You will need to set a Screen Time PIN so the block cannot be disabled without it.

Screen Time is less granular than Android options — you cannot set schedules or block sites only during certain hours — but it is the strongest option available on iOS. If you need more control, the only alternative is to use a VPN app that offers content filtering, though these are less reliable and often require a subscription.

Blocking sites at the network level on Android

If you want to block a site across all apps and browsers without installing an app, you can change your phone's DNS settings. This method blocks the site at the network level, so it affects Chrome, Safari, and every other app that uses the internet. Open Settings, go to Network & Internet or Connections, tap Wi-Fi, long-press your network, and select Modify. Change the DNS to a filtering service like Cloudflare for Families (1.1.1.3 and 1.0.0.3) or OpenDNS.

This approach works only on Wi-Fi networks you control. When your phone connects to a different network (like a coffee shop or school), the DNS change does not explore, so the block is bypassed. It also requires you to know the site's domain name, and some sites use multiple domains, so you may need to block several addresses to cover all entry points.

DNS blocking is useful if you want a passive, always-on block that does not require an app, but it is less flexible than a dedicated blocking app. You cannot set schedules, and you cannot block individual pages — only entire domains.

What happens when you try to visit a blocked site

When you navigate to a blocked site in Chrome, the behavior depends on which blocking method you used. With Family Link, the page straightforward will not load and you will see a message that the site is blocked by your parent or guardian. With a third-party app like Freedom, you will see a block screen with the app's logo and a message that the site is blocked; you can request to unblock it, but the app will ask for your PIN.

With DNS filtering, the page will not load and you will see a "server not found" error, which looks like a normal connection problem. With Screen Time on iOS, you will see a message that the site is restricted and an option to request access from the account holder. In all cases, the block is when ready — there is no delay or warning before the page is prevented from loading.

Frequently Asked Questions

Can I block a website just in Chrome, or does it block it everywhere?

It depends on the method. Family Link and third-party apps like Freedom block sites across all apps and browsers. DNS filtering also blocks at the network level. Screen Time on iOS blocks across all browsers. If you want to block a site only in Chrome and nowhere else, Chrome Mobile does not offer that option — you would need to use a desktop browser extension instead.

What if someone uninstalls the blocking app?

On Android, if you set a PIN in the blocking app, uninstalling it requires you to enter the PIN first. On iOS, Screen Time requires a PIN to disable, so uninstalling an app does not bypass it. Family Link cannot be removed without the parent's approval. If you are blocking your own device and you know the PIN, you can disable the block anytime.

Does blocking a site in Chrome affect other browsers like Safari or Firefox?

Chrome's own settings do not block sites in other browsers. But Family Link, third-party apps, DNS filtering, and Screen Time all work across all browsers because they operate at a higher level than Chrome itself. If you use one of those methods, the block applies everywhere on the device.

Can I block a site on mobile but not on desktop?

Yes. Blocking apps and Family Link are device-specific, so you can set them up on your phone but not on your computer. DNS filtering is also per-device. If you want to block a site on all your devices, you would need to set it up separately on each one, or use a service like Freedom that syncs across devices.

What is the difference between blocking and restricting?

Blocking prevents access entirely — the site will not load. Restricting usually means limiting when or how often you can visit. Family Link and Screen Time can do both. Third-party apps like Freedom typically block during set hours but allow access at other times. DNS filtering is always-on blocking with no time-based options.
