The fastest way to block sites on Chrome Android
Google Chrome on Android does not have a built-in site blocker, so you have three real options: use SafeSearch (Google's filter for search results), install a third-party app that blocks at the network level, or use your phone's native parental controls to restrict Chrome itself. SafeSearch is the quickest — it filters explicit content from Google Search on any device signed into that Google account — but it only works on search results, not on sites you visit directly by typing a URL.
If you need to block specific websites or prevent access to entire categories (adult sites, gambling, violence), a network-level blocker like OpenDNS Home, Cloudflare for Families, or Family Link (Google's own parental control app) will work across all apps on the phone, not just Chrome. These require you to change your phone's DNS settings or install the app and grant it device administrator access.
Key Takeaways
- SafeSearch filters search results but not direct website visits, and you turn it on in your Google account settings, not in Chrome itself.
- Network-level blockers like Cloudflare for Families or OpenDNS Home block sites across all apps by changing your phone's DNS address.
- Google Family Link is Google's official parental control app and can block apps, set screen time limits, and restrict Chrome access entirely.
- Android's native parental controls (Google Play Family Library) can restrict app installation but do not block websites within apps.
Turning on SafeSearch for your Google account
SafeSearch is a filter that removes explicit images and adult content from Google Search results. It works on any device where you are signed into your Google account, including Chrome on Android. To turn it on, open any web browser on your phone, go to google.com, tap the profile icon in the top right, and select Manage your Google Account. Tap the Search settings tab (you may need to scroll to find it), then toggle SafeSearch to on.
SafeSearch will now filter results on that account across all devices. The limitation is that it only affects Google Search — if someone types a URL directly into the address bar or uses a different search engine, SafeSearch does not block it. It also does not prevent access to sites that are not indexed by Google or that do not have explicit content in their titles or descriptions.
Using Cloudflare for Families to block categories of sites
Cloudflare for Families is a free DNS filter that blocks malware, adult sites, and other categories you choose. It works by changing your phone's DNS address (the service that translates website names into numbers your phone can reach). To set it up, go to Settings on your Android phone, tap Network & Internet, then Advanced, then Private DNS. Enter family.cloudflare-dns.com as the DNS provider.
Once you save that setting, all websites on your phone will be filtered through Cloudflare's blocklist. You can choose which categories to block (adult content, gambling, social media, streaming video) by visiting families.cloudflare.com from a computer and signing in with your account. The filter applies to all apps on the phone, not just Chrome, and it works even if someone tries to use a different browser.
The trade-off is that Cloudflare for Families blocks at the DNS level, which means you cannot easily whitelist a single site — you either block a whole category or none of it. If you need finer control (blocking specific URLs but allowing others in the same category), a parental control app is a better choice.
Setting up Google Family Link for full device control
Google Family Link is Google's official parental control app. It lets you set screen time limits, restrict app installation, see your child's location, and block Chrome entirely if needed. To set it up, the parent installs Family Link on their own phone, then adds the child's account. The child's phone will receive a Family Link app that enforces the parent's rules.
In Family Link, tap the child's account, then Controls on Google Play, and set the content rating to restrict what apps can be installed. For Chrome specifically, go to App activity and toggle Chrome off to block it entirely, or use Screen time to set daily limits. Family Link does not have a built-in website blocker within Chrome, but blocking the app itself prevents access to any websites through it.
If you want to block specific websites while still allowing Chrome, Family Link alone is not enough — you would need to combine it with Cloudflare for Families or OpenDNS Home running on the same device.
Using OpenDNS Home for network-level blocking
OpenDNS Home is another DNS-level filter similar to Cloudflare. You change your phone's DNS settings to 208.67.222.123 (for blocking adult content) or 208.67.220.123 (for blocking adult content plus other categories). Go to Settings, Network & Internet, Advanced, Private DNS, and enter the OpenDNS address.
OpenDNS Home is free and blocks across all apps. You can log into your OpenDNS account at opendns.com to see what was blocked and adjust categories. Like Cloudflare, it works at the DNS level, so it blocks entire categories rather than individual URLs. It is a good choice if you want a straightforward, set-it-and-forget-it filter without installing an app.
Blocking sites within Chrome using Android's app restrictions
Android does not have a built-in way to block websites within Chrome without using a third-party tool. However, you can restrict Chrome itself through Google Play Family Library by setting content ratings for app installation, or by using Family Link to disable the app entirely. If you need to block specific sites while keeping Chrome available, you must use a DNS filter (Cloudflare or OpenDNS) or a dedicated parental control app.
Some phones have a Digital Wellbeing feature (in Settings) that lets you set app timers and focus modes, but this does not block specific websites — it only limits how long the app can be used per day.
Comparing your blocking options
| Method | What It Blocks | How to Set It Up | Best For |
|---|---|---|---|
| SafeSearch | Explicit content in Google Search results only | Google Account settings | Quick filtering of search results |
| Cloudflare for Families | Categories of sites (adult, gambling, malware) across all apps | Change DNS in phone settings | Blocking entire categories without an app |
| OpenDNS Home | Categories of sites across all apps | Change DNS in phone settings | straightforward category-based blocking |
| Google Family Link | Can block Chrome entirely, set screen time, restrict app installation | Install app on parent and child phones | Full parental control with location tracking |
What happens if someone changes the DNS settings back
If you set up a DNS filter like Cloudflare or OpenDNS, a user with access to phone settings can change the DNS address back and bypass the filter. To prevent this, use Google Family Link, which requires a parent PIN to change settings, or enable Restricted Mode in your phone's Settings under Security (though this is less common on newer Android versions).
For the strongest protection, combine Family Link (which locks down settings changes) with a DNS filter (which blocks at the network level). This way, even if someone tries to change the DNS, Family Link will prevent them from accessing Settings without the parent PIN.
Frequently Asked Questions
Does SafeSearch block all inappropriate content?
No. SafeSearch only filters Google Search results — it does not block sites you visit by typing a URL directly, and it does not work on other search engines like Bing or DuckDuckGo. It also misses content that is not explicitly labeled as adult material.
Can I block specific websites instead of whole categories?
DNS filters like Cloudflare and OpenDNS block by category, not by individual URL. To block specific sites, you would need a dedicated parental control app like Screen Time or Net Nanny, which cost money and require installation. Family Link does not have this feature either.
Will a DNS filter slow down my internet?
No. Cloudflare for Families and OpenDNS are fast — they may actually be faster than your default DNS. The filtering happens at the DNS level, before the request reaches your phone, so there is no noticeable speed loss.
What if my child uses a different browser, like Firefox or Samsung Internet?
A DNS filter like Cloudflare or OpenDNS blocks sites across all browsers and apps, so switching browsers will not bypass it. Family Link can only block Chrome specifically — other browsers would still work unless you disable them separately in Family Link's app controls.
Can I block sites on my own phone without parental controls?
Yes. You can use Cloudflare for Families or OpenDNS on your own phone by changing the DNS settings. You can also use SafeSearch on your Google account. These are not parental controls — they are filters you set for yourself.
