How to Block Websites on iPhone: A Simple Step-by-Step Guide

If you need to block distracting, unsafe, or adult websites on an iPhone, you are in the right place. Maybe you are setting up parental controls, limiting your own screen time, or keeping a work device focused on the task at hand. Whatever the reason, iPhone gives you a built-in way to block websites quickly, without installing extra apps.

In this guide, you will learn how to block websites on iPhone using Apple’s Screen Time settings, which is the easiest and most reliable method for most users. I’ll walk you through each tap step by step, show you how to block specific sites or entire categories, and cover what to do if your settings look a little different. The process usually takes just a few minutes, and once it is set up, the blocks stay in place until you change them.

Quick Summary

Here is the fastest way to block websites on iPhone:

• Go to Settings > Screen Time
• Turn on Screen Time if it is not already enabled
• Tap Content & Privacy Restrictions
• Go to Content Restrictions > Web Content
• Choose Limit Adult Websites or Allowed Websites Only
• Add specific websites to the Never Allow list

Tutorial – How to Block Websites on iPhone Using Screen Time

This method uses Apple’s built-in website filtering tools. It is the best option if you want to block one site, multiple sites, or restrict web access on a child’s iPhone.

Step 1: Open Screen Time in Settings

Go to Settings, then tap Screen Time.

If Screen Time is already enabled, you will see several usage and restriction options on the screen. If it is not enabled yet, the screen will prompt you to turn it on first. This is the control center for website blocking on iPhone, so everything starts here.

Step 2: Turn On Content & Privacy Restrictions

Tap Content & Privacy Restrictions, then switch it on if the toggle is off.

Once this is enabled, iPhone opens the door to parental controls and content filters. If the switch is off, website restrictions will not work yet, so this step is required before you can block anything. After turning it on, you should see more restriction options appear below the toggle.

Step 3: Open Content Restrictions

Tap Content Restrictions.

This menu controls what type of content the iPhone will allow, including apps, movies, music, and websites. After you tap it, you should see several categories on the next screen. Look for the web-related setting, which is what we need next.

Step 4: Tap Web Content

Select Web Content.

This is where Apple lets you choose how strict the browser filter should be. You will usually see three choices:

• Unrestricted Access
• Limit Adult Websites
• Allowed Websites Only

If you want to block a single site while keeping normal browsing open, Limit Adult Websites is usually the best option.

Step 5: Choose the Right Blocking Option

Pick “Limit Adult Websites” or “Allowed Websites Only,” depending on how strict you want the restriction to be.

If you select Limit Adult Websites, iPhone will automatically block Apple-detected adult sites and let you add specific websites to a blacklist. If you choose Allowed Websites Only, the phone blocks almost everything except the sites you approve. This is the strongest option and works well for younger children or tightly managed devices.

Step 6: Add Websites to the Never Allow List

Under Limit Adult Websites, tap Add Website in the Never Allow section.

Enter the full website address, such as youtube.com or reddit.com, then tap Done or Back to save it.

After you add the site, the iPhone should block it in Safari and, in many cases, in other browsers too. If the website is already open, the page may not disappear instantly, but a refresh or new visit should trigger the block.

Step 7: Set a Screen Time Passcode

If prompted, create a Screen Time Passcode.

This passcode keeps other people from changing the restrictions you just set. It is a smart move if you are setting up a child’s phone or want to avoid undoing the block too easily. Without a passcode, anyone with access to the phone can turn the filter off.

Step 8: Test the Block

Open Safari and try visiting the blocked website.

You should see a message saying the page is restricted or unavailable. If the site still loads, double-check that Screen Time restrictions are on and that the website address was entered correctly. It helps to test with both Safari and any other browser app installed on the phone.

Alternative Methods and Edge Cases

Here are a few other ways to block websites on iPhone, depending on your setup.

• Block websites in Safari only

  • If you only use Safari, Screen Time is still the best choice, but remember that other browsers like Chrome or Firefox may also need testing. Screen Time restrictions usually apply across browsers, not just Safari.

• Use Allowed Websites Only for a child’s device

  • This mode is ideal if you want to create a very controlled browsing environment. The phone will only open websites you manually approve, which is much stricter than blocking a few sites individually.

• Block websites through router or DNS settings

  • If you want the block to apply to every device on your Wi-Fi network, you can use router-level blocking or a DNS filtering service. This is more advanced, but useful for home-wide filtering.

• Temporarily disable the restriction

  • Go back to Settings > Screen Time > Content & Privacy Restrictions and turn the toggle off. You will likely need the Screen Time passcode to do this.

• Use third-party parental control apps

  • Apps like Bark, Qustodio, or Net Nanny can give you more detailed website monitoring and filtering. These can be helpful if Apple’s built-in controls are not enough.

Frequently Asked Questions

Can I block a single website on iPhone?

Yes. Use Screen Time > Content & Privacy Restrictions > Content Restrictions > Web Content, then add the site under Never Allow.

Does blocking websites work in all browsers?

Usually yes. Screen Time restrictions apply broadly across web browsers on iPhone, not only Safari.

How do I unblock a website later?

Go back to the same Web Content menu, find the website under Never Allow, and remove it from the list.

Will blocked websites still open in private browsing mode?

No, Screen Time restrictions should still apply in private mode. Private browsing does not bypass website blocks.

Do I need a passcode to block websites?

You do not need one to set the block, but a Screen Time Passcode is strongly recommended to prevent the setting from being changed easily.

Can I block only adult websites?

Yes. Choose Limit Adult Websites in the Web Content settings, and iPhone will automatically filter adult content.

Tips

• Use Limit Adult Websites if you want a balance between safety and convenience. It blocks a lot without making the phone too restrictive.
• Use Allowed Websites Only for children or shared devices where you want strict control over browsing.
• Keep the Screen Time Passcode in a safe place. If you forget it, changing restrictions becomes much harder.
• Double-check the website address before saving it. A small typo can stop the block from working.
• Remember that website blocks do not remove access from apps. For example, blocking a website does not always stop access to the same service inside an app.
• If you manage a child’s iPhone, review the block list every so often. Websites and apps change quickly, and your controls should keep up.

Troubleshooting

• The website is still loading after I blocked it

  • Close the browser completely, then reopen it. Then try the site in a new tab or fresh session. Some pages may stay open until reloaded.

• I cannot find Screen Time

  • Open Settings and use the search bar at the top to search for Screen Time. On older iOS versions, the menu structure may look slightly different, but the feature is still there.

• My changes keep getting undone

  • Make sure Content & Privacy Restrictions are on and that you set a Screen Time Passcode. Without a passcode, someone else can easily disable the block.

• The website still works in another browser

  • Check whether that browser is installed and updated. Screen Time usually blocks across browsers, but if the app behaves oddly, restart the iPhone and test again.

• I forgot my Screen Time passcode

  • Use the Forgot Passcode? option in Screen Time, if available, or reset it using your Apple ID if you set it up earlier.

Conclusion

Blocking websites on iPhone is straightforward once you know where to look. For most users, Screen Time is the fastest and best built-in solution, whether you want to block one distracting site or lock down browsing more tightly.

If you follow the steps above, you should have a working website block in just a few minutes. From there, you can adjust the settings at any time, add more sites, or remove them when the restriction is no longer needed.
