How to Block Websites on Chrome – All Devices Guide

Many users want to block websites on Chrome for productivity, parental control, or security reasons. The right approach depends heavily on whether you use a desktop computer, an Android phone, an iPhone, or an iPad, and whether you want to install extensions or rely on built-in tools. Chrome itself does not offer a universal “block this site” toggle on mobile devices, so the practical options vary by platform and use case, according to research from Comodo, Freedom, and ESET.

For personal desktop use, browser extensions provide the simplest path. On mobile, the situation is more complex: Android Chrome lacks a built-in blocker, and iOS Chrome does not support extensions at all. Enterprise environments have their own managed solutions. This guide covers every major method—extension-based, no-extension, free, and enterprise—so you can choose the one that fits your device and needs.

Below you will find platform-specific instructions, a comparison of costs and reliability, and clarification on what works and what remains uncertain across different approaches.

Block Websites on Chrome Desktop (Windows & Mac)

Key insights to keep in mind:

• Chrome’s built-in URL blocking is designed for managed devices (school/work) and requires Chrome Browser Cloud Management.
• Browser extensions like BlockSite offer the simplest blocking for personal desktop use but require installing third-party code.
• On mobile, Android Chrome allows blocking via third-party apps (e.g., BlockSite) that use accessibility or VPN services; iOS Chrome has no native blocking without an app or Safari Content Blocker.
• Free methods exist (hosts file, router settings) but require technical know-how and are not Chrome-specific.

Block Websites on Chrome Mobile (Android, iPhone, iPad)

Blocking websites on mobile Chrome requires different tactics depending on the operating system. Chrome on Android and iOS does not include a native site-blocking toggle for general users, so you will need to use system-level settings or third-party apps, as detailed by Freedom and Anysecura.

Android: Family Link, Private DNS, and Third-Party Apps

Google’s Family Link can block specific sites in Chrome on a child’s supervised Android device through Manage sites / Blocked controls, according to ESET. For device-wide filtering, you can configure Private DNS by pointing the device to a filtering DNS provider, which blocks sites across all apps, including Chrome, as noted by Comodo. Third-party apps such as BlockSite, Freedom, and Qustodio also work on Android using device permissions or VPN-based filtering.

iPhone and iPad: Screen Time and Content Filters

Apple’s built-in Screen Time is the primary free option on iPhone and iPad. You navigate to Settings → Screen Time → Content & Privacy Restrictions → Content Restrictions → Web Content, then choose Limit Adult Websites or Allowed Websites Only, and add URLs under Never Allow. This restriction applies to Chrome and all other browsers because it is enforced at the device level, not inside the browser itself, according to Anysecura and ESET.

Can You Block Sites on Chrome Mobile Without an App?

On Android, you can use Private DNS or Family Link without installing a separate app. On iPhone and iPad, Screen Time is built into the OS and requires no additional download. However, neither platform offers a Chrome-specific toggle that works without some form of system configuration or third-party tool, according to research from Comodo and Freedom.

How to Block Websites on Chrome Without an Extension or App

If you prefer not to install browser extensions or mobile apps, several system-level methods can block websites on Chrome. These approaches work across the entire device or network rather than inside the browser alone.

Desktop: Hosts File, Router Controls, and DNS Filtering

The simplest no-extension method on desktop is editing the hosts file, which redirects specific domains to a local address and effectively blocks them. Router-level blocking and DNS filtering are also viable; these block sites for every device on the network, not just the computer running Chrome, as explained by Security.org. For organizations, Chrome Enterprise supports URLBlocklist and URLAllowlist policies that apply to managed browsers without requiring extensions.

Mobile: Built-in OS Restrictions

On Android, Family Link (for child accounts) and Private DNS (for device-wide filtering) are built-in options that do not require a separate app. On iPhone and iPad, Screen Time provides the same capability at the OS level. None of these methods require a Chrome extension, and they remain active regardless of which browser you use.

Free Methods to Block Sites on Chrome (Desktop & Mobile)

Cost is a common concern. Fortunately, several effective website blocking methods cost nothing.

Free Built-in Methods by Platform

On iPhone and iPad, Screen Time is completely free and built into the operating system, as confirmed by Freedom, Anysecura, and ESET. On Android, Family Link for child accounts and Private DNS with a filtering provider are both free, according to Comodo and ESET. On desktop, the hosts file, router controls, and DNS filtering cost nothing but require some technical setup, as noted by Security.org.

Free Extensions for Desktop

BlockSite and uBlock Origin are popular free extensions for desktop Chrome. BlockSite focuses specifically on site blocking, while uBlock Origin is primarily an ad blocker but can also block websites. Both are available on the Chrome Web Store and require no payment to use.

What Has Changed in Chrome’s Website Blocking Over Time?

The topic is largely evergreen, but a few developments are worth noting. Chrome’s transition to Manifest V3, which began rolling out in 2024, has affected how blocking extensions work. Some extensions that relied on older APIs may have reduced functionality. Additionally, Google has continued to update Chrome Enterprise policies, making URLBlocklist more reliable for managed environments. Mobile Chrome has not introduced native URL blocking for general users in recent releases, and no major changes are expected in the immediate future.

1. 2020: Google introduces URLBlocklist and URLAllowlist policies for Chrome Enterprise, enabling admins to block specific sites on managed devices.
2. 2021: Apple strengthens Screen Time with more granular web content controls, affecting Chrome behavior on iOS and iPadOS.
3. 2022: Google expands Family Link features on Android, allowing parents to block specific websites in Chrome on supervised devices.
4. 2024: Manifest V3 rollout begins, changing how Chrome extensions handle network requests and site blocking. Some ad blockers and site blockers lose functionality or require updates.
5. 2025: Third-party apps such as BlockSite and Freedom continue to support Android and iOS Chrome through VPN-based filtering and accessibility services. Screen Time remains the primary built-in method on Apple devices.

What Is Certain and What Remains Unclear About Blocking Websites on Chrome?

Why People Block Websites on Chrome: Context and Background

Users block websites for a range of reasons: productivity (avoiding social media or news during work hours), parental control (restricting children’s access to inappropriate content), security (preventing access to known malware or phishing sites), and personal discipline (reducing distractions). Chrome’s flexibility means multiple methods exist, each with trade-offs in effort, cost, and scope. Understanding the device and management environment is key to choosing the right approach. A desktop user with administrator rights has more options than a parent setting up a child’s Android phone or an IT admin managing a fleet of corporate laptops.

Sources and Official Guidance on Blocking Websites in Chrome

Several authoritative sources provide documentation and step-by-step instructions for blocking websites on Chrome. Below are key quotes from official and expert sources.

“Blocked URLs—URLs that you want to prevent users from accessing.”

— Google Chrome Enterprise Help

“Tap 0 blocked sites (under the Manage sites heading) followed by + Add a website.”

— Avast blog

“Go to ‘Content filters’ > ‘Blocked sites.’ Then, enter the URL of the site you want to block.”

— ESET blog

These sources cover enterprise policy configuration, desktop extension usage, and mobile content filtering respectively.

What to Keep in Mind Going Forward

Chrome’s transition to Manifest V3 may continue to affect how blocking extensions function, so users who rely on extensions should monitor updates. Enhanced built-in parental controls could appear in future Chrome releases on mobile. For now, the most reliable path depends on your platform: use extensions on desktop, Screen Time on iPhone/iPad, and Family Link or Private DNS on Android. If you manage many devices in a company, the Google Chrome Enterprise URL Blocking help page provides the official documentation for URLBlocklist policies.
