How to Block Porn on Safari (iPhone, iPad and Mac)

You can search every Safari setting and never find a switch called “block porn.”

The switch lives in Screen Time.

Here is how to block porn on Safari on an iPhone, iPad or Mac, followed by the one step that decides whether the block lasts.

Turn on Apple's adult website filter, add the sites it misses, then put the Screen Time passcode in someone else's hands.

Safari is the window, not the lock

Safari displays the page. Screen Time decides whether the page can open.

That distinction matters. A Safari extension can be removed inside Safari. A Screen Time restriction sits one layer above it.

On iPhone or iPad, use this path

1. Open Settings, then tap Screen Time.
2. Tap Content & Privacy Restrictions and turn it on.
3. Open App Store, Media, Web, & Games.
4. Tap Web Content.
5. Choose Limit Adult Websites.
6. Under Never Allow, add any site the automatic filter misses.

Those are Apple's current menu names. The filter applies to web content across the device, so switching from Safari to another iPhone or iPad browser should not be the easy way around it.

On a Mac, use this path

1. Open System Settings, then click Screen Time.
2. Turn on App & Website Activity if Screen Time is off.
3. Click Content & Privacy.
4. Open App Store, Media, Web, & Games.
5. Beside Safari, choose Limit Adult Websites.
6. Click Customize to add URLs under Restricted.

Apple labels this Mac control under Safari. If Chrome or Firefox is installed, test those browsers separately. A filter you did not test is a guess.

The automatic list will miss sites

“Limit” is the honest word. Apple classifies known adult domains, but new sites, mirror domains and explicit pages inside ordinary platforms can get through.

Add misses manually. If this is a young child's device, use the approved-websites-only option instead. It starts closed and opens only the sites you choose.

The passcode is the real block

If you know the Screen Time passcode, you can undo the filter during the same minute you want porn.

Ask a trusted person to create the code and keep it. For a child, manage Screen Time through Family Sharing from the parent account.

Close the routes Safari never sees

Screen Time's web filter handles websites. It does not erase downloaded files or clean explicit posts out of every social, messaging and cloud-storage app.

Delete saved material. Remove apps that became another route. On iPhone and iPad, restrict new app installations if replacing Safari is part of the pattern.

Test it like you plan to bypass it

Open one known adult domain, a private window, another browser and a link inside a social app. Test on Wi-Fi and mobile data.

Every route that still opens tells you where the next layer belongs.

When Screen Time is too easy to undo

Move the filter away from Safari and the device.

A Wi-Fi-level block covers every browser on that network. A DNS-level service can travel with the device, depending on its setup (DNS is the layer that turns a web address into a server, underneath the browser and the apps).

Keep the password with someone else. More filters under the same password do not create more distance.

Use the guide for your actual device

This page owns the Safari question. The device guides cover the holes around it.

Use the full iPhone steps or iPad steps for app restrictions, supervision and off-device layers. For Chrome, use the Chrome guide.

Do the step that survives tonight

Turning on Limit Adult Websites takes two minutes.

Handing away the passcode is the part that makes those two minutes matter.
