Key Takeaways
- Screen Time is the answer. Apple’s Content & Privacy Restrictions inside Screen Time is the official way to block websites on iPhone, and it works across Safari and most other browsers.
- Always set a Screen Time passcode. Without one, a child can turn off the restrictions in under a minute. Use a 4-digit code different from your phone unlock.
- Block alternative browsers, not just websites. Screen Time’s website rules behave inconsistently in Chrome and Firefox. Use App Limits to block the browsers themselves so kids stay on Safari, where your rules apply.
- For young kids, consider a closed video environment. An endless blocklist is reactive. Apps like Jellies give children a pre-reviewed space where there’s nothing to block in the first place.
One quick search for a homework topic. One wrong link in a sidebar. That’s all it takes for a child holding an iPhone to land somewhere you’d rather they didn’t.
iPhones don’t block websites by default. The Safari setting most parents look for doesn’t exist there. It lives inside iPhone parental controls, under Screen Time, two menus deep. This article shows how to block websites on iPhone in five practical ways, starting with Apple’s built-in tools and covering alternatives for households where Screen Time isn’t the right fit. Every step works on iOS 17 and iOS 18, and each method uses tools you already have or can set up for free.
Why Block Websites on iPhone?
Blocking websites on iPhone protects children from adult content, prevents distraction during homework or sleep, and keeps screen time focused on what you’ve approved. Apple’s Screen Time settings can have a full block in place in under five minutes, with no third-party apps needed.
Protection from inappropriate content. Children encounter inappropriate content more often than parents realize. Research from Internet Matters found that 21% of children reported seeing violent content online, while only 14% of parents thought their child had. The gap matters: most exposure happens without a parent in the room.
Focus during homework and bedtime. Phones are designed to pull attention. For homework, sleep, and meals, blocking a handful of distracting websites is often more effective than asking a child to self-regulate. Pair website blocks with consistent screen time rules to make limits stick.
Productivity on your own phone. Adults block websites too, for focus, for sleep, or to break a social media habit. The methods below work the same way on your own iPhone.
5 Ways to Block Websites on iPhone
There are five reliable ways to block websites on iPhone. The first uses Apple’s built-in Screen Time and works for most parents. The next four are for specific situations: a Safari-only setup, alternative browsers like Chrome, no-Screen-Time households, and managing a child’s iPhone remotely. You can jump straight to the method that fits your situation.
Method 1: How to Block Websites on iPhone Using Screen Time
Screen Time’s Content & Privacy Restrictions is Apple’s official way to block websites on iPhone. It works across Safari and most other browsers, blocks adult content automatically, and lets you ban specific sites or allow only the ones you choose. Setup takes about three minutes.
Screen Time has been Apple’s parental control hub since iOS 12 and remains the primary blocking tool in iOS 17 and iOS 18. Inside Screen Time, the relevant setting is Content & Privacy Restrictions, with three useful modes for blocking websites. Pick the one that matches your child’s age and your trust level.
Option A: Block Adult Websites Automatically
This is the simplest setting. Apple maintains its own blocklist of adult sites, and turning it on filters them out across Safari with no list to manage yourself.
1. Open Settings and tap Screen Time.
2. Tap Content & Privacy Restrictions and turn the switch on.
3. Tap Content Restrictions, then Web Content.
4. Select Limit Adult Websites.
Apple’s list is good but not perfect. Some adult sites slip through, and some safe sites get caught. Pair this setting with Option C below to cover the gaps.
Option B: Allow Only Approved Websites (Whitelist Mode)
This is the strictest setting and works best for children under 10. Only the URLs you add will load. Everything else, including search engines, returns a blocked page.
1. Settings → Screen Time → Content & Privacy Restrictions → Content Restrictions → Web Content.
2. Select Allowed Websites Only.
3. Tap Add Website and enter each URL the child can visit.
Review the list weekly. Whitelist mode blocks educational sites the child may need, and adding them mid-homework is faster than fielding the inevitable complaints.
Option C: Block Specific Websites You Choose
This is the middle option. The rest of the internet stays available, but specific URLs you choose are blocked. Best for blocking individual time-wasters without restricting everything.
1. Settings → Screen Time → Content & Privacy Restrictions → Content Restrictions → Web Content.
2. Make sure Limit Adult Websites is selected.
3. Under Never Allow, tap Add Website.
4. Enter the full URL, including https:// (for example, https://www.youtube.com).
One gotcha: many sites have separate mobile subdomains. Kids who get blocked from youtube.com may try m.youtube.com instead. Add both.
Lock Settings With a Screen Time Passcode
This is the step most parents skip, and it makes everything above pointless. Without a Screen Time passcode, a child can turn off Content & Privacy Restrictions in seconds.
1. Settings → Screen Time → tap Use Screen Time Passcode.
2. Enter a 4-digit code your child doesn’t know. Confirm.
3. When prompted, add your Apple ID for passcode recovery.
Do not reuse your phone unlock code. If your child watches you unlock your phone, they have your Screen Time passcode too. Our 12 ways kids bypass Screen Time post covers the other workarounds children use, so you know what to watch for.
Method 2: How to Block Websites on iPhone Safari Only
There is no separate Safari-only blocking setting on iPhone. The Web Content restrictions inside Screen Time, covered above, are the Safari block. They apply to regular tabs and Private Browsing the same way.
Many parents search for “block websites on Safari iPhone” expecting a setting inside Safari itself. There isn’t one. Apple chose to centralize all web blocking inside Screen Time so it applies to every Apple browser at once.
If you’ve completed Method 1, you’ve already blocked websites in Safari. The same setting also catches blocked sites in Google’s search results, so kids can’t preview them from the results page either. The catch is that Safari isn’t the only browser on iPhone. Method 3 covers Chrome, Firefox, and the others.
Method 3: How to Block Websites on Chrome, Firefox, and Other iPhone Browsers
Third-party browsers on iPhone use Apple’s web engine but don’t all respect Screen Time’s Web Content rules. The safer fix is to block the alternative browsers themselves, so kids can only use Safari, where your restrictions apply.
Chrome, Firefox, DuckDuckGo, and Brave on iOS all use Apple’s WebKit engine because Apple requires it. In theory, your Screen Time blocks should carry over. In practice, the behavior is inconsistent between browsers and changes between iOS updates.
Rather than chase down each browser’s quirks, prevent your child from installing or using alternatives in the first place.
To restrict browser installs:
1. Settings → Screen Time → Content & Privacy Restrictions → iTunes & App Store Purchases.
2. Set Installing Apps to Don’t Allow.
3. If alternative browsers are already installed, go to Settings → Screen Time → App Limits and add Chrome, Firefox, and any others to a one-minute daily limit. The browsers will be locked after the first minute each day, which is effectively never.
Don’t try to delete Safari. iOS lets you hide it through Allowed Apps but not remove it, and Safari is where your blocks work.
Method 4: How to Block Websites on iPhone Without Screen Time
Parents who don’t want to use Screen Time, or who want a second layer of protection, can block websites at the network level. DNS filters and router parental controls work for every device on the network, not just the iPhone.
Screen Time can be bypassed if a child learns the passcode. Network-level blocks survive that, because the block happens before the iPhone makes the connection at all.
Three options, from easiest to most thorough:
- DNS filter. Free family DNS services like CleanBrowsing Family, NextDNS, and OpenDNS Family Shield block adult content for any device using them. Set the DNS in Settings → Wi-Fi → tap the network → Configure DNS → Manual, then add the addresses from the service you chose.
- Router-level parental controls. Most modern routers (Eero, Google Nest Wifi, Asus, and others) include website blocking. Open your router app and look for a Family or Restrictions section.
- Content blocker apps from the App Store. BlockSite, AdGuard, and 1Blocker can layer extra rules on Safari. Most have a free tier and a paid version with more features.
DNS and router blocks have one limitation: they don’t work when your child connects through cellular data instead of Wi-Fi. For that, you still need Screen Time.
Method 5: How to Block Websites on Your Child’s iPhone Remotely
If the iPhone belongs to a child, use Family Sharing and remote Screen Time from your own phone. You can block websites, change passcodes, and review web activity without holding the child’s device.
The methods above assume the iPhone is in your hands. This one is for parents managing a child’s device from another room or another city. Before starting, kid-proof your iPhone with a full Family Sharing setup if you haven’t already.
To set up remote blocking:
1. On your iPhone: Settings → Family. Add your child’s Apple ID to your family group.
2. Open Settings → Screen Time and tap your child’s name under Family.
3. Apply the website blocks from Methods 1 and 3. Changes sync to the child’s device automatically.
Turn on Ask to Buy while you’re there. It stops the child from installing browser apps that bypass the blocks. Every download request routes to your phone for approval first.
Common Mistakes Parents Make When Blocking Websites on iPhone
Most parents set up Screen Time once, then assume the block holds. Here is what actually goes wrong.
- Skipping the Screen Time passcode. Without it, the child can turn restrictions off in seconds. Set a unique 4-digit code that isn’t your phone unlock code.
- Blocking the wrong URL format. Many sites have separate mobile subdomains. Add both example.com and m.example.com to your Never Allow list.
- Forgetting Chrome and Firefox. Screen Time’s behavior in third-party browsers is inconsistent. Block the browser apps themselves using App Limits.
- Not reviewing after iOS updates. Major iOS updates occasionally reset Content Restrictions or change menu names. Check your settings after every September Apple event.
When Blocking Isn’t Enough: A Different Approach for Young Kids
Blocking websites is reactive. You’re naming things you don’t want your child to see, one URL at a time, and the list never ends. For older children, that’s fine. For younger ones, a different approach often works better.
A closed video environment skips the blocklist entirely. Instead of trying to block everything bad, you give your child a smaller space where every piece of content has already been reviewed for safety. That’s what Jellies does. Every video on the app is hand-checked by our team, with no ads, no autoplay surprises, and no comments section feeding videos kids shouldn’t see.
If your child is under 10 and you find yourself adding new sites to your Never Allow list every week, browsing what’s safe by design at jelliesapp.com is worth a look.
Wrapping Up
Five methods, in order of how often you’ll use them: Screen Time for the everyday blocks, the same Screen Time setting if you came looking for Safari controls, App Limits for alternative browsers, network-level filters for households that want a second layer, and remote Screen Time through Family Sharing for a child’s own iPhone. Set the Screen Time passcode today, turn on Limit Adult Websites, and you’ve handled the most important five minutes of work.
For households with Android phones in the mix, our block inappropriate websites on Android post covers the same setup on the other side of the ecosystem.
Frequently Asked Questions
Can I permanently block a website in Safari on iPhone?
Yes. Screen Time’s Never Allow list keeps a website blocked until you remove it. The block survives restarts, iOS updates, and Private Browsing, as long as your Screen Time passcode is set.
How do I block a specific website on my iPhone?
Go to Settings → Screen Time → Content & Privacy Restrictions → Content Restrictions → Web Content. Under Never Allow, tap Add Website. Enter the URL with https:// at the front, and add the mobile subdomain (m.example.com) too if the site has one.
Can my child get around the website block on iPhone?
Yes, in three cases: if you didn’t set a Screen Time passcode, if they can install Chrome or another browser, or if they know your Apple ID password. Set the passcode, restrict app installs, and keep your Apple ID private.
How do I block websites in Chrome on iPhone?
Screen Time restrictions are inconsistent in Chrome. The reliable fix is to block Chrome itself with a one-minute daily App Limit, leaving Safari as the only usable browser. Your Web Content rules apply normally in Safari.
Does blocking websites work in Safari Private Browsing?
Yes. Screen Time’s Web Content restrictions apply to Private Browsing the same way they apply to regular tabs. A blocked site will not load in either mode.
