The internet has a lot of good in it, but it also has plenty you don’t want showing up on your screen or your child’s. Explicit content, gambling sites and violent material are often one wrong click away, whether through a pop-up, a misleading link or a harmless-looking search.

The good news is that you can block inappropriate websites on almost every device you own. Some methods are built into your phone or laptop and take a few minutes to set up. Others give you stronger, harder-to-bypass protection. This guide covers both, device by device.

Why you should block inappropriate websites

People block websites for different reasons:

  • Protecting children from explicit or violent content they may stumble upon by accident
  • Breaking a habit, such as watching adult content or visiting gambling sites
  • Staying focused at work or while studying
  • Keeping a shared family device safe for everyone who uses it

Whatever your reason, the goal is the same: stop the content before it reaches the screen, so you don’t have to rely on willpower or constant supervision.

How to block inappropriate websites on iPhone and iPad

Apple’s Screen Time has a built-in adult content filter.

  1. Open Settings and tap Screen Time.
  2. Tap Content & Privacy Restrictions and turn it on.
  3. Go to the web content option (labelled Web Content or Store, Web, Siri & Game Center Content, depending on your iOS version).
  4. Select Limit Adult Websites.
  5. To block a specific site, tap Add Website under Never Allow and enter the URL.
  6. Set a Screen Time passcode so the settings can’t be changed without it.

Limitation: this filter works best in Safari and may miss content inside other apps and browsers. It also relies on a list, so new or lesser-known sites can slip through.

How to block inappropriate websites on Android

Android doesn’t have a single built-in adult website filter, but you have a few good options.

Use Private DNS

A family-safe DNS service filters adult sites across your whole phone, not just one browser.

  1. Open Settings and go to Network & internet (or Connections on Samsung phones).
  2. Tap Private DNS.
  3. Choose Private DNS provider hostname.
  4. Enter a family filter hostname, such as family-filter-dns.cleanbrowsing.org.
  5. Tap Save.

Use Google Family Link for children

If you are setting up a child’s phone, Google Family Link lets parents filter sites in Chrome, approve apps and set screen time limits from their own phone.

Limitation: Private DNS can be switched off in a few taps, and a VPN can bypass it entirely. Family Link is designed for children’s accounts, not for adults trying to control their own browsing.

How to block inappropriate websites on Windows

Use Microsoft Family Safety

  1. Create a family group at the Microsoft Family Safety website or app.
  2. Add the user’s Microsoft account as a family member.
  3. Under Content filters, turn on Filter inappropriate websites and searches.
  4. Add any specific sites you want blocked.

This filter applies to Microsoft Edge, so you may need to block other browsers for it to work fully.

Edit the hosts file

The hosts file lets you block specific sites on the whole computer.

  1. Search for Notepad, right-click it and choose Run as administrator.
  2. Open C:\Windows\System32\drivers\etc\hosts (set the file type to All Files to see it).
  3. At the bottom, add a line for each site, for example: 127.0.0.1 example.com
  4. Save the file and restart your browser.

Limitation: the hosts file blocks only the exact sites you list. It can’t keep up with the thousands of new sites that appear every day.

How to block inappropriate websites on Mac

  1. Open System Settings and click Screen Time.
  2. Click Content & Privacy and turn it on.
  3. Open the store and web content settings.
  4. Under web content, select Limit Adult Websites.
  5. Add specific sites to the restricted list if needed.
  6. Turn on Lock Screen Time Settings and set a passcode.

Like on iPhone, this works best in Safari. Advanced users can also edit the hosts file through Terminal, which works the same way as on Windows.

How to block inappropriate websites on Google Chrome

Chrome doesn’t have a built-in adult website blocker for regular accounts, but you can tighten it up:

  • Turn on SafeSearch: go to Google’s SafeSearch settings and select Filter. This hides explicit results in Google Search.
  • Turn on YouTube Restricted Mode: in YouTube, open your profile menu and switch on Restricted Mode.
  • Install a blocker extension: an extension can filter content on every website you visit, not just in search results. This is the most reliable option on Chrome.

Limitation: SafeSearch only filters search results. If someone types a site’s address directly, it won’t stop them.

How to block inappropriate websites on your home Wi-Fi

Changing the DNS on your router filters every device connected to your home network, including smart TVs and gaming consoles.

  1. Open your router’s admin page (usually printed on a sticker on the router).
  2. Find the DNS settings, often under Internet or WAN settings.
  3. Replace the existing DNS with a family-safe service, such as Cloudflare for Families (1.1.1.3 and 1.0.0.3) or OpenDNS FamilyShield (208.67.222.123 and 208.67.220.123).
  4. Save and restart the router.

Limitation: this only works on your home Wi-Fi. Once a phone switches to mobile data, the filter no longer applies.

Why built-in methods are often not enough

Built-in settings are a good start, but they share a few weak spots:

  • They are easy to turn off, especially if you are trying to control your own habits.
  • VPNs and incognito mode can get around many of them.
  • List-based filters miss new sites and content inside apps like Instagram, Reddit or Telegram.
  • Each device needs a different setup, which is hard to manage across a family.

This is why many people add a dedicated blocker app on top of the built-in settings.

Block inappropriate websites on every device with BlockP

BlockP is a free, AI-powered blocker that filters adult and inappropriate content on Android, iOS, Windows, macOS and Chrome. It is trusted by over 1 million users and holds a 4.6-star rating.

Instead of relying only on a list of banned sites, BlockP analyses the text, images and video on a page as it loads and blocks explicit content in real time. That means it can catch new or disguised content that list-based filters miss.

Here is what makes it stronger than built-in settings:

  • AI-powered blocking: detects and hides explicit images, videos and semi-nude content across websites and apps.
  • Works in incognito and with VPNs: VPN detection keeps the blocking active even when someone tries to hide their activity.
  • Custom blocklists: block any website or keyword, including gambling, shopping or any site that distracts you.
  • Social media blocker: block search on Instagram, YouTube, Telegram and other apps, and turn off Reels and Shorts.
  • Password protection and uninstall prevention: the blocker can’t be switched off or deleted without permission.
  • Accountability partner: a trusted person holds the password to change your settings.
  • SafeSearch enforcement: filters explicit results on major search engines automatically.

The core features are free, and BlockP Premium adds extra protection and priority support. You can install it from the Google Play Store, the App Store or the Chrome Web Store

Frequently asked questions

Can I block inappropriate websites for free?

Yes. Screen Time on iPhone and Mac, Microsoft Family Safety, Private DNS and family DNS services are all free. BlockP’s core features are also free on all major platforms.

What is the best way to block adult websites on a phone?

The most reliable approach is to combine a built-in setting with a dedicated blocker app. A blocker app like BlockP covers browsers and apps, works in incognito mode and can’t be removed easily.

Does incognito mode bypass website blockers?

It can bypass some browser-level settings, but system-wide blockers and apps that support incognito mode still work. BlockP continues to filter content in incognito mode.

How do I block inappropriate websites on my child’s phone?

Use Google Family Link on Android or Screen Time on iPhone to set up parental controls, then add a blocker app with password protection so your child can’t change the settings.

Can I block inappropriate content on Instagram and YouTube?

Built-in settings like YouTube Restricted Mode help a little. For stronger control, BlockP can block search, Reels, Shorts and explicit content inside social media apps.
