On desktop, install a site-blocking extension from the Chrome Web Store and add websites in its controls; for a child's supervised account, open Family Link > Controls > Google Chrome and Web. On iPhone and iPad, use Apple's Screen Time website controls, with the menu path for your software version below.
The short version
- Use a desktop extension for your own browsing.
- Use Family Link for a child's supervised Google account.
- Use Screen Time website restrictions on iPhone or iPad.
- Use filtering DNS for devices that use your network's DNS.
- Block the Chrome app if access to the whole browser is the problem.
- Use administrator policies for managed Chrome browsers.
| Method | What it does | Time | Use it when |
|---|---|---|---|
| Desktop extension | Blocks selected websites | A few minutes | You want to limit your own browsing |
| Family Link | Restricts a supervised account | A few minutes | You manage a child's Google account |
| Screen Time | Restricts website access | A few minutes | You use an iPhone or iPad |
| Filtering DNS | Filters domain lookups | About 10 minutes | You want filtering beyond one browser, on the router or one device |
| App blocking | Stops access to Chrome | A few minutes to configure | Individual website blocks are insufficient |
| Managed policies | Applies an administrator's URL rules | About 15 minutes | You administer work or school browsers |
Use a Chrome extension on desktop
Open the Chrome Web Store in a normal desktop Chrome window and choose an extension whose description includes website blocking. Select Add to Chrome, review any requested permissions, then select Add extension to approve them. Approve only an extension you trust.
Select the extension's icon to the right of the address bar and follow its instructions to add your websites. Open a listed address to check the result before relying on the block. Treat this as a tool for your own browsing, since Chrome lets users turn extensions off or remove them.
Chrome extensions work on desktop computers only, even if you open the store on your phone. For your own phone, consider setting filtering DNS on that device using the DNS method below.
Block websites for a child with Family Link
Open Family Link, select your child, then tap Controls > Google Chrome and Web. Pick Allow all sites or Try to block explicit sites to keep your own list of blocked sites alongside it, or Only allow approved sites to limit your child to the sites you approve. With either of the first two, sites you add under Blocked sites stay blocked.
Under Manage sites, open Blocked sites, tap Add a website and enter the website or domain. Use Approved sites when you want to allow an address instead. With Only allow approved sites, your child can visit only the sites you allow.
Check the exact address when a block misses: a website entry does not automatically cover differently named subdomains or country domains. Google distinguishes a specific website from a broader domain entry, so choose the type that matches your intention.
Use Screen Time on iPhone or iPad
iOS 27 and iPadOS 27
With the updated family controls, open Settings > Family on your own device, tap your child's name, then tap Apps & Websites > Restrictions. Under Websites, choose Filtering, then Limit Adult Websites or Approved Websites Only. The latter turns on Ask to Browse, requiring approval for new sites.
To keep a chosen site out, use Approved Websites Only and decline its request. To block a site you approved earlier, open Settings > Family > your child > Apps & Websites, tap it under Allowed, then tap Block Website twice to confirm. Enter your Screen Time passcode if asked.
The updated controls require compatible software across the family group and a parental-controls upgrade. If you cannot update every device, keep the previous controls or adjust restrictions directly on the child's device.
iOS 26 and earlier
On iOS 26 and iPadOS 26, open Settings > Screen Time. To block sites for your child, tap your child's name. Tap Content & Privacy Restrictions and turn it on, then open App Store, Media, Web, & Games > Web Content.
Choose Limit Adult Websites, tap Add Website below Never Allow and enter the URL. Apple also documents this website path for iOS 18.
Apple describes current coverage as Safari and supported browser apps, so check the blocked address in Chrome on the child's device. Use Apple's website approval controls to finish setup or manage an already approved site.
Set up DNS filtering for your network
Filtering DNS is useful when you want domain filtering beyond one browser. Set the filtering service's addresses on your router for network coverage, or configure an individual device instead. Coverage depends on that device actually using the selected DNS service.
For OpenDNS FamilyShield's preset adult-content filtering, use 208.67.222.123 and 208.67.220.123. FamilyShield filters categories rather than providing your own arbitrary website list. OpenDNS Home offers customizable filtering and uses the standard addresses 208.67.222.222 and 208.67.220.220; complete its account and filtering setup before relying on custom rules.
On Google Nest Wifi or Google Wifi, open Google Home > Home > Wifi > Network settings > Advanced Networking > DNS. Choose Custom, enter the primary and secondary server addresses, then tap Save. For another router, use its maker's DNS instructions rather than assuming these Google Home menus apply.
If sites still open, check for a VPN, manually assigned DNS or a browser DNS provider overriding the router. An alternate provider can bypass these rules. If internet access stops after a change, check the addresses and revert to the previous working DNS configuration.
Block Chrome itself when needed
If the goal is to prevent browser access, use app blocking rather than building a long website list. In Family Link, select your child and open Screen time > Time limits > App limits. If Chrome is listed and can be blocked, select it, tap the Allowed toggle so its status becomes Blocked, then tap Done.
On a supervised device, app management requires Android 6.0 or later, or ChromeOS 71 or later. Blocking Chrome through App limits needs Android 7 or later. If Chrome came preinstalled as a system app, Family Link may not offer the block. A block takes about five minutes on an online device, or waits until the device connects.
Sign in at account.microsoft.com/family as a family organizer and select the family member. Choose Windows, select the Apps, features, and games tab, select More options next to Google Chrome, then select Block app if Chrome appears. Microsoft's website filters work in Microsoft Edge; blocking Chrome as an app does not add website filtering inside Chrome.
Use managed Chrome controls at work
For managed browsers, an administrator can apply URL rules instead of asking each user to install a blocker. Sign in to the Google Admin console with an administrator account. Open Menu > Devices > Chrome > Settings, which requires the Mobile Device Management administrator privilege. For Chrome Enterprise Core, use Menu > Chrome browser > Settings instead.
Select the organizational unit or configuration group if you need to narrow the scope. Open Content > URL Blocking, enter addresses under Blocked URLs and any permitted exceptions under Blocked URL exceptions, then click Save. Check exceptions carefully because the allowlist takes precedence over the blocklist.
Local administration on Windows, Mac or Linux uses URLBlocklist and optional URLAllowlist policies. Use Google's platform policy instructions for the deployment steps. Restart Chrome, open chrome://policy, click Reload policies and check that the policies have OK status and the intended values.
When blocked websites still open
Check which Chrome profile is open before changing the rules. On Windows, Mac, Linux, iPhone and iPad, signing out of Chrome ends the browsing session where Family Link's Chrome restrictions apply. Another browser can also fall outside those restrictions.
On a shared computer, a child can switch to another Chrome profile that has no Family Link rules. If an unsupervised profile is how blocked sites still open, delete a user profile in Chrome for that profile. This erases its bookmarks, history, passwords and settings from that computer.
For an extension, open More > Extensions > Manage extensions and check that it is turned on. Extensions do not run in Incognito by default. If your blocker supports it, select Details and turn on Allow in incognito, then check a blocked address again.
Frequently Asked Questions
Can Chrome block websites without an extension?
A supervised account can use Family Link, and managed Chrome can use administrator URL policies. On iPhone or iPad, use the appropriate Screen Time website controls; filtering DNS is another option for devices using that service.
What is the easiest way to block a website on Chrome desktop?
For your own browsing, a site-blocking extension is a practical starting point. Install it from the Chrome Web Store, add your websites using its controls and check the result.
Does Microsoft Family Safety block websites in Chrome?
Its website and search filters work with Microsoft Edge. Family Safety can instead block the Chrome app where app blocking is available, which prevents browser access rather than filtering individual Chrome pages.
Can a child bypass Chrome website blocks?
Google lists the sign-out limit for Windows, Mac, Linux, iPhone and iPad, where a child can sign out or use another browser. Family Link's Chrome settings are harder to get around on a supervised Android phone or Chromebook, where Incognito is disabled for the supervised account.
Does FamilyShield block any website I choose?
FamilyShield uses preset adult-content categories. Choose a service with customizable filtering, or use Family Link or an extension, when you need a list of specific websites.
Why does a blocked site open in Incognito?
Desktop extensions do not run in Incognito by default. Check the blocker's Details page for Allow in incognito, enable it if supported and check the site again.
