Safari blocks pop-ups by default, and you can turn that off in Settings

Safari on iPhone automatically blocks most pop-ups to reduce clutter and protect against unwanted ads. If a website you trust needs pop-ups to work — for example, a banking site that opens account statements in a new window, or a tool that displays results in a pop-up — you can disable the block. The setting is in iPhone Settings, not in Safari itself, and it applies to all websites unless you later turn it back on.

Pop-up blocking is a blanket setting: you cannot allow pop-ups for one website and block them for another without changing the setting each time. Most people leave blocking on and only disable it temporarily when they need a specific pop-up to work.

Key Takeaways

  • Open Settings, scroll to Safari, and toggle off "Block Pop-ups" to allow all pop-ups on all websites.
  • Pop-ups are blocked by default because most are advertisements, but some legitimate websites need them to function.
  • The setting affects Safari across all websites — you cannot block pop-ups on some sites and allow them on others.
  • After you finish using the website that needs pop-ups, turn the setting back on to restore the default protection.

Steps to disable pop-up blocking in Safari

Open the Settings app on your iPhone. Scroll down the list until you see Safari — it is usually near the bottom, after Mail and Maps.

Tap Safari to open its settings page. Look for the option labeled "Block Pop-ups" — it appears as a toggle switch, usually in the middle of the screen. The toggle is normally on (green), which means pop-ups are being blocked.

Tap the toggle to turn it off. The switch will turn gray, and pop-ups will now load on websites you visit in Safari. Close Settings and return to Safari. Reload the website that needs the pop-up by pulling down on the page and waiting for it to refresh, and the pop-up should now appear.

When to turn pop-up blocking back on

Once you have finished using the website that required pop-ups, return to Settings > Safari and toggle "Block Pop-ups" back on. This restores your default protection against unwanted advertisements and reduces the clutter on most websites.

Leaving pop-up blocking off permanently is not recommended. Most pop-ups are advertisements or tracking scripts that slow down browsing and consume data. The few websites that genuinely need pop-ups to function are the exception, not the rule. Turning the setting back on takes only a few seconds and protects you from the majority of pop-ups you will encounter.

Why Safari blocks pop-ups in the first place

Pop-ups were originally a legitimate web feature — they opened new windows for things like image galleries, calculators, or login forms. Over time, advertisers and tracking companies began using pop-ups to display ads, collect data, and redirect users to other sites. This made pop-ups annoying and sometimes harmful to the browsing experience.

Safari's pop-up blocker stops most of these unwanted windows from opening. It does not block pop-ups that you trigger yourself — for example, if you click a button that says "View Details," that window will still open. The blocker only stops pop-ups that load automatically when you visit a page, which is where most of the unwanted content comes from.

If a pop-up still does not appear after disabling the block

Some websites use other methods to display content that look like pop-ups but are not technically pop-ups. These might be modal windows, overlays, or expandable sections that Safari does not treat as pop-ups. Disabling pop-up blocking will not affect these types of windows.

If you have turned off pop-up blocking and the window still does not appear, the website may be using a different method to display the content. Try refreshing the page by pulling down and releasing, clearing Safari's cache (Settings > Safari > Clear History and Website Data), or contacting the website's support team to ask if they have an alternative way to access that feature.

Pop-up blocking on other Apple devices

The same setting exists on iPad and Mac. On iPad, the steps are identical: Settings > Safari > toggle off "Block Pop-ups." On Mac, open Safari, go to Safari menu > Settings, click the Security tab, and uncheck "Block pop-ups."

If you use Safari across multiple devices, the setting does not sync automatically. You will need to change it on each device separately if you want consistent behavior. This means disabling pop-up blocking on your iPhone will not automatically disable it on your iPad or Mac.

Frequently Asked Questions

Can I allow pop-ups for just one website?

No. Safari's pop-up blocker is an all-or-nothing setting — it either blocks pop-ups on every website or allows them on every website. If you need pop-ups for one site, you must disable blocking, use that site, and then turn blocking back on.

Will disabling pop-up blocking slow down my iPhone?

It may slightly increase data use if websites load pop-up advertisements, but it will not slow down the iPhone itself. Most of the slowdown from pop-ups comes from the ads themselves loading and running, not from Safari processing them.

What if I accidentally allow a pop-up and want to close it?

Tap the back button or swipe left to go back to the previous page. If the pop-up opened in a new tab, tap the tab switcher (the overlapping squares icon) and close the pop-up tab by swiping up on it.

Does turning off pop-up blocking affect other security features?

No. Disabling pop-up blocking only affects pop-ups. Safari's other protections — blocking trackers, warning about fraudulent websites, and preventing auto-play of videos — remain active regardless of the pop-up setting.
