How to Block Ads in Safari on an iPhone

Cleaning Up Your Mobile Browsing Experience

Browsing the modern internet on a small smartphone screen can be an incredibly frustrating experience. Between the massive autoplaying video advertisements, the screen-covering newsletter pop-ups, and the banners that shift the text just as you are trying to click a link, reading a simple news article can feel like navigating a minefield.

These advertisements are not just visually annoying; they are actively draining your iPhone’s battery and eating up your monthly mobile data allowance by forcing your phone to download heavy video files in the background.

Unlike Google Chrome on Android (which actively prevents you from blocking ads to protect Google’s main source of revenue), Apple’s Safari browser on the iPhone fully supports third-party ad blockers. Installing one takes only a few minutes and will completely transform how fast and clean your mobile browsing experience feels.

Step 1: Download an Ad Blocker from the App Store

Because Apple tightly controls the iOS ecosystem, you cannot install a browser extension directly from a website like you can on a desktop computer. Instead, Safari relies on standalone “Content Blocker” apps downloaded from the official App Store.

1. Open the App Store on your iPhone.
2. Tap the Search tab at the bottom of the screen.
3. Search for a reputable ad blocker. Two of the most trusted, effective, and privacy-respecting options are AdGuard (free) and 1Blocker (freemium/paid).
4. Tap Get to download and install the app onto your iPhone.
5. Once installed, open the app once to complete any initial setup screens, but do not worry about tweaking all the settings just yet.

Step 2: Enable the Blocker in Safari Settings

Just downloading the app is not enough. For security reasons, Apple does not allow third-party apps to automatically attach themselves to Safari. You must manually grant the app permission to filter your web traffic.

1. Open the main Settings app on your iPhone.
2. Scroll down the long list of system apps and tap on Safari.
3. Under the “General” section, tap on Extensions.
4. You will see a list of the ad-blocking filters provided by the app you just downloaded (for example, AdGuard might install five or six different specific filters for things like Ads, Trackers, and Social Media widgets).
5. Toggle the switches to the ON (green) position for all the filters associated with your new ad blocker.

Step 3: Test the Ad Blocker

Now that the extension is enabled, the changes should take effect immediately.

1. Open the Safari app.
2. Navigate to a website that is notoriously heavy with advertisements (local news websites or recipe blogs are usually good test candidates).
3. You should instantly notice that the page loads significantly faster, the video boxes are gone, and the text fills the screen normally without shifting around.

How to Temporarily Disable the Blocker for a Specific Website

While ad blockers are fantastic, they occasionally break legitimate functionality on certain websites. For example, if you are trying to buy airline tickets, the ad blocker might aggressively mistake the seat-selection pop-up window for an advertisement and block it, preventing you from completing your purchase.

If a website is acting strangely or refusing to load properly, you can quickly turn the ad blocker off for that specific page without diving back into the main Settings app.

1. While looking at the broken website in Safari, look at the address bar at the bottom of the screen.
2. Tap the ‘aA’ icon on the left side of the address bar.
3. In the menu that pops up, tap Turn Off Content Blockers.
4. The page will instantly refresh with all ads (and potentially the broken functionality) restored.

Safari will remember this choice. Every other website on the internet will remain ad-free, but this specific site will be allowed to show ads until you open that ‘aA’ menu again and select Turn On Content Blockers.
