How to Block a Website on Chrome: Easy Methods for PC & Mobile (2025 Guide)

How to Block a Website on Chrome

There’s a certain irony in how the internet the very thing that powers our productivity can also so easily derail it. One minute you’re searching for an article on marketing strategies, and the next you’re twenty minutes deep into a rabbit hole of cat videos or reading heated comment threads that add nothing to your day. If you’ve ever been there (and let’s be honest, most of us have), you’ve probably wondered if it’s possible to just block those distracting websites altogether.

That’s where learning how to block a website on Chrome becomes a small but powerful act of reclaiming your focus whether you’re trying to be more productive, reduce screen time, or simply protect your kids from inappropriate sites.

But while the intention is clear, the method isn’t always obvious. Chrome doesn’t exactly hand you a big red “Block Website” button. Still, with a little know how, you can set up barriers that actually work and in this guide, we’ll explore every possible way to do it, from built in settings to clever extensions and even system level tweaks.

So grab your metaphorical toolbox. Let’s learn how to take back your browsing time, one blocked site at a time.

Why Block a Website on Chrome in the First Place?

Before we jump into the “how”, it’s worth pausing for a second to explore the “why”. Blocking websites isn’t about being overly strict or policing your digital life. It’s about intentional browsing.

Think about how easy it is to lose hours online. Social media apps are designed to keep us scrolling, news websites refresh every minute with “breaking” stories that tug at our curiosity. Even harmless sites like YouTube or Reddit can quietly consume hours that could’ve gone toward something meaningful finishing a project, reading a book, or simply resting.

Here are some of the most common reasons people decide to block websites:

a. Boosting Productivity
Distractions are the nemesis of focus. Blocking sites like Facebook, Twitter, or Instagram during work hours can help you stay in “deep work” mode longer that precious mental state where you’re actually making progress.

b. Protecting Children
Parents often want to restrict access to adult or harmful content. Blocking specific sites ensures a safer, more age appropriate online experience for kids.

c. Avoiding Procrastination
Sometimes, it’s not even about the internet being dangerous it’s just too tempting. Blocking shopping sites, gaming platforms, or streaming services helps you avoid wasting time when you should be doing something else.

d. Maintaining Mental Health
Some websites can trigger stress, comparison, or information overload. Blocking them can serve as digital self care a way to maintain peace of mind in a noisy online world.

e. Controlling Data Usage or Bandwidth
In certain cases, especially on shared or limited networks, blocking websites can help manage data consumption.

Blocking websites isn’t about avoiding the web, it’s about reshaping your relationship with it. And the good news is Chrome gives you plenty of ways to do that.

Method 1: Using Chrome Extensions to Block Websites

Let’s start with the easiest and most flexible option, extensions.

Chrome’s vast ecosystem of extensions makes it incredibly simple to block websites temporarily, permanently, or even according to a schedule. These small tools can turn Chrome into a productivity powerhouse.

Here are a few of the most popular and effective ones:

1. BlockSite

Best for Everyday blocking, productivity schedules, and simple control.

BlockSite is one of the most downloaded and user friendly extensions available. Once installed, it lets you:
  • Block specific URLs or entire domains.
  • Create custom block lists.
  • Set schedules (e.g., block YouTube from 9 a.m. to 5 p.m.).
  • Redirect blocked sites to something more positive, like a motivational quote.
  • Protect settings with a password great if you’re trying to avoid turning it off impulsively.
It’s also available on mobile, meaning you can sync your blocked sites between your phone and desktop perfect for keeping consistency across devices.

How to use BlockSite:
  • Open Chrome and go to the Chrome Web Store.
  • Search for “BlockSite”.
  • Click “Add to Chrome” and follow the setup prompts.
  • Once installed, click the BlockSite icon next to the address bar.
  • Enter the URLs you want to block and hit “Add Item”.
That’s it. You’re done. You can now browse without temptation lurking in a new tab.

2. StayFocusd

Best for Serious productivity and time management.

If you’ve ever said, “I’ll just check Instagram for five minutes”, and then lost half your afternoon, StayFocusd was built for you. It’s more than just a blocker it’s a discipline enforcer.

You can:
  • Allow a set amount of time per day on certain websites.
  • Choose which sites are restricted.
  • Nuke” all distractions for a set period when you really need to concentrate.
Once your allotted time runs out, StayFocusd makes those sites inaccessible until the next day. It’s a bit like having a digital accountability partner that doesn’t give in when you do.

Personal note: The first time I used StayFocusd, I tried to outsmart it by uninstalling it mid day. The extension had already thought of that it gave me a warning that uninstalling wouldn’t reset the timer. Point, StayFocusd.


3. LeechBlock NG

Best for Power users and detailed customization.

Originally built for Firefox, LeechBlock NG is now available for Chrome too. It offers fine grained control over your blocking rules, letting you specify:
  • Exact times and days to block each site.
  • Delays before a page loads (to discourage impulsive visits).
  • Daily or hourly limits.
It’s perfect for those who like control and maybe a little flexibility in how they block sites.

Method 2: Using Chrome’s Built In Tools

While Chrome doesn’t have a direct “website blocking” button, it does offer some built in tools that can be repurposed to limit or restrict access particularly if you want something lightweight and extension free.

1. Using Chrome’s “Supervised Users” (via Family Link)

If you’re managing Chrome for a child or a family member, Google’s Family Link feature lets you control what they can access.

You can:
  • Block specific websites.
  • Approve or deny access to sites in real time.
  • Set screen time limits.
  • Monitor browsing activity.

How to set it up:
  • Download the Family Link app (available on both Android and iOS).
  • Create a Google account for your child (or link their existing one).
  • Open the Family Link dashboard and select “Manage settings” > “Google Chrome”.
  • Choose between allowing all sites, blocking explicit ones, or creating a custom allow/block list.
While this setup is mainly for parental control, adults can use it too if they prefer a built in, extension free approach.

2. Using Chrome’s SafeSearch and Restricted Mode

If your main goal is to filter inappropriate or explicit content rather than productivity distractions, enabling SafeSearch can help.

While it doesn’t block all websites, it filters out explicit results on Google Search and YouTube which can be a big step toward cleaner browsing, especially on shared devices.

To turn on SafeSearch:
  • Go to Google Search Settings.
  • Check “Turn on SafeSearch”.
  • Save your preferences.
It’s not foolproof, but it’s a simple layer of protection that complements other blocking methods.

Method 3: Blocking Websites Without Extensions

If you prefer a more “techy” solution or you simply don’t want to rely on third party tools you can block websites directly through your computer’s hosts file or network router.

These methods block sites system wide, meaning even other browsers won’t be able to access them.

1. Editing the Hosts File (Windows & macOS)

The hosts file is a small system file that maps hostnames (like facebook.com) to IP addresses. By redirecting certain domains to your local machine (127.0.0.1), you effectively block them.

Here’s how:
On Windows:

  • Press Windows + S and type “Notepad”.
  • Right click Notepad > “Run as administrator”.
  • Open this file: 
    • C:\Windows\System32\drivers\etc\hosts
  • At the bottom, add this line for each site you want to block: 
    • 127.0.0.1 facebook.com 
    • 127.0.0.1 www.facebook.com
  • Save the file and restart Chrome.

On macOS:
  • Open Terminal (Applications > Utilities).
  • Type: 
    • sudo nano /etc/hosts
  • Enter your password.
  • Add the same “127.0.0.1” lines.
  • Press Control + O to save and Control + X to exit.
  • Restart your browser.
Now, try visiting the blocked site you’ll find it doesn’t load.

2. Using Your Router’s Blocking Features

Many modern routers let you block websites at the network level. This means every device connected to your Wi-Fi will be restricted.

To do this:
  • Log into your router’s admin page (usually something like 192.168.0.1).
  • Enter your admin username and password.
  • Look for “Access Restrictions” or “Parental Controls”.
  • Add the URLs you want to block.
  • Save and restart your router.
This method is perfect for households, offices, or shared networks where you want consistent rules.

Method 4: Using Chrome on Mobile Devices

If you’re often tempted by distractions while browsing on your phone, blocking websites on Chrome Mobile can be just as important.

Here’s how to do it depending on your device.

On Android

Unfortunately, Chrome for Android doesn’t have built in website blocking but you can still use:
  • BlockSite app (Android version): Syncs with your desktop extension and works across browsers.
  • Google Family Link: Manage which sites are accessible on a child’s account.
  • Third party browsers like Brave or Firefox Focus: These offer built in blocking tools.


On iPhone (iOS)

You can use Screen Time, Apple’s built in restriction feature:
  • Open Settings > Screen Time > Content & Privacy Restrictions.
  • Tap Content Restrictions > Web Content.
  • Choose Limit Adult Websites or Allowed Websites Only.
  • Tap “Add Website” under “Never Allow” and enter the URLs you want to block.
This works even if you’re using Chrome instead of Safari, since the restriction applies device wide.

Creative and Gentle Ways to Reinforce Website Blocking

Blocking websites doesn’t always have to feel harsh or restrictive. In fact, the most effective blockers are the ones that encourage mindful habits rather than punish you for slipping up.

Try these small but clever tactics:
  • Redirect to inspiration, instead of a generic “Blocked” message, use extensions that redirect you to a motivational site like Zen Habits or your task manager.
  • Use gentle nudges, extensions like Momentum or Forest reward you for staying focused by planting virtual trees or showing inspiring quotes.
  • Block by schedule, not permanently, you don’t have to block YouTube forever just during work hours.
  • Set a “digital detox” challenge, commit to blocking a set of distracting sites for 30 days. Track how much more focused or calm you feel.
These tweaks help reframe blocking not as restriction but as empowerment.

Final Thoughts: It’s About Balance, Not Control

Learning how to block a website on Chrome isn’t just a technical skill it’s a mindset shift. It’s about realizing that attention is one of your most valuable resources in the digital age, and you have every right to guard it.

When you block distractions, you’re not cutting yourself off from the world you’re simply choosing where to place your focus. It’s a quiet act of digital self respect.

Whether you’re using extensions like BlockSite, system tweaks like the hosts file, or built in features like Family Link, the method matters less than the intention behind it. The goal isn’t to live a “blocked” life it’s to live a focused one.

So next time you catch yourself mindlessly typing “youtube.com” into the address bar, remember you’re the one holding the keys. Chrome just happens to be the car.
