You can’t install an ad blocker inside Google Chrome on an iPhone, because Chrome for iPhone doesn’t support browser extensions. What you can do is turn on Chrome’s built-in pop-up blocker, which stops many of the most disruptive ads, and then decide whether you need stronger blocking from Safari content blockers or a network-level (DNS) filter.
The quickest fix takes about 30 seconds: open Chrome, tap More (the three dots), then Settings, Content Settings, Block Pop-ups, and make sure the switch is on. If you want real ad blocking on websites, the most reliable option on an iPhone is to install a content blocker app from the App Store and use it with Safari.
Quick Answer
- Open Chrome on your iPhone and tap More, then Settings.
- Tap Content Settings, then Block Pop-ups, and turn the switch on.
- For fuller ad blocking, install a Safari content blocker from the App Store.
- Go to Settings, Apps, Safari, Extensions, and turn the blocker on.
- Browse in Safari when you want ads blocked, or consider a DNS-based filter if you must stay in Chrome.

What Chrome on iPhone Can and Can’t Do
This guide covers Google Chrome and Safari on iPhone with a current version of iOS, as of September 2026. The same steps generally apply on iPad. Menu names can shift slightly between app versions, so if a label looks a little different on your screen, look for the closest match.
On a computer, most people block ads in Chrome with an extension, which is a small add-on program that changes how the browser works. Chrome for iPhone has no extension store and doesn’t run Chrome extensions, so the ad blockers you may know from a desktop computer can’t be added to it. Even ad-blocking companies say this in their own help pages: their Chrome extension works on computers, not on Chrome for iPhone.
Here is what that means in practice:
- Built in to Chrome on iPhone: a pop-up blocker and Safe Browsing, which warns you about dangerous sites. Both help, but neither removes regular banner or video ads from web pages.
- Not available in Chrome on iPhone: extensions, and the separate “intrusive ads” setting. Google’s help page for that ads setting only lists computer and Android versions of Chrome.
- Available in Safari: content blockers, which are App Store apps that let Safari block ads, trackers, cookies, images, pop-ups and other page content. According to Apple, you can use more than one at a time.
- Available across the whole phone: DNS filtering, which blocks known ad servers for every app, including Chrome. This is more advanced and depends on the service you trust.
What you’ll need:
- An iPhone with Chrome installed. If you don’t have it yet, see our guide on installing Google Chrome on an iPhone.
- An Apple Account signed in to the App Store if you plan to download a content blocker.
- A few minutes to test a site you visit often, so you can see what changed.
Method 1: Turn On Chrome’s Pop-Up Blocker
A pop-up is a new window or tab that a website opens on its own, often to show an ad. Chrome for iPhone can block these. The setting is usually on by default, but it’s worth checking, especially if someone else has used your phone or you allowed pop-ups for a site in the past.
These steps follow Google’s help page on how to block or allow pop-ups in Chrome on iPhone and iPad.
- Open the Chrome app on your iPhone.
- Tap More. This is the button with three dots, usually at the bottom right of the screen. Expected result: A menu slides up with options such as bookmarks, history and settings.
- Tap Settings. You may need to scroll the row of icons sideways to find it.
- Scroll down and tap Content Settings.
- Tap Block Pop-ups.
- Turn the Block Pop-ups switch on. Expected result: The switch shows as on, and Chrome now stops sites from opening unwanted pop-up windows.
- Tap Done or go back to close Settings and return to browsing.
When Chrome blocks a pop-up, you’ll see a Pop-ups blocked message at the bottom of the page. Some sites use pop-ups for useful things, such as a payment window or a sign-in box. If a site you trust needs one, tap Always show under that message. That allows pop-ups only for that site, while the blocker stays on everywhere else.
Keep your expectations realistic. The pop-up blocker doesn’t remove banner ads, sponsored links, ads placed between paragraphs, or video ads that play inside a page. It targets extra windows and tabs, which are among the most annoying and sometimes the most dangerous kind of ad.
Add Safe Browsing Protection in Chrome
Some aggressive ads try to send you to fake prize pages, phishing sites that steal passwords, or pages that push unwanted downloads. Safe Browsing is Google’s warning system for dangerous sites. It won’t hide ads, but it can stop a bad ad from leading you somewhere harmful.
According to Google’s page on choosing your Safe Browsing protection level, the steps are:
- Open Chrome and tap More, then Settings.
- Tap Privacy and security.
- Tap Safe Browsing.
- Choose a level. Standard protection is the default. Enhanced protection is Google’s strongest option and checks more of what you visit with Google. No protection is not recommended. Expected result: Your choice is marked, and Chrome warns you before opening sites it knows are dangerous.
Enhanced protection sends more browsing information to Google in exchange for faster warnings. If that trade-off bothers you, Standard protection still covers known dangerous sites.
Method 2: Use a Safari Content Blocker
If you want ads actually removed from web pages on your iPhone, Safari is the browser built for it. Apple lets App Store apps act as content blockers for Safari. Once turned on, a content blocker tells Safari which ads, trackers and other page items to skip loading. These blockers work in Safari (and in some apps that open web pages with Safari’s viewer), not inside Chrome.
Step 1: Install a content blocker
- Open the App Store on your iPhone.
- Tap Search and type “content blocker” or “ad blocker for Safari.”
- Read the app’s description, privacy details and recent reviews before you download. Look for an app that clearly says it works as a Safari content blocker.
- Tap Get (or the price) and install the app.
- Open the app once and follow any setup screens. Some apps need you to choose filter lists, such as ads, trackers or annoyances. Expected result: The app tells you to turn it on in Settings.
Many content blockers are free, and some charge for extra features. Be cautious with any app that asks for broad permissions it doesn’t need, or that wants you to install a profile when all you asked for is a Safari blocker.
Step 2: Turn the blocker on in Settings
Apple’s help page on Safari settings and content blockers gives this path:
- Open the Settings app.
- Tap Apps, then tap Safari.
- Tap Extensions. Expected result: You see a list of Safari extensions and content blockers installed on your iPhone.
- Tap your new content blocker and turn it on. You can turn on more than one blocker if you use several.
- Open Safari and visit a site you know shows ads. Expected result: Fewer ads load, and pages may load faster.
On older versions of iOS, the Safari settings may appear directly in the main Settings list instead of under Apps. If you don’t see Apps, scroll down and tap Safari.
Step 3: Turn on Safari’s own pop-up blocker
Safari also has a pop-up blocker and a scam warning. Apple’s page on blocking pop-ups in Safari says to open Settings, tap Apps, tap Safari, and turn on Block Pop-ups. On the same screen, turn on Fraudulent Website Warning to get alerts about suspected phishing sites. If you later need pop-ups for a single trusted site, our guide on enabling pop-up windows in Safari walks through it.
Optional: Make Safari your default browser
If links from Mail, Messages and other apps open in Chrome, you’ll miss your new blocker. You can change that. Apple’s guide to changing default apps on iPhone says to go to Settings, tap Apps, tap Default Apps, then choose the browser feature and pick Safari. The exact label for the browser option can vary by iOS version.
You don’t have to give up Chrome completely. Some people keep Chrome for signed-in Google services and use Safari with a blocker for news and recipe sites, where ads are heaviest.
Method 3: DNS-Based Ad Filtering (Advanced)
If you need to stay in Chrome, network-level filtering is the main way to cut down ads there. It’s more technical, so read this whole section before you set anything up.
DNS, or Domain Name System, is the internet’s address book. Every time a page loads, your phone asks a DNS server where to find each piece of the page, including the ads. A filtering DNS service keeps a list of known ad and tracking servers and refuses to give out their addresses. The page still loads, but many of the ads can’t.
How people usually set this up on an iPhone:
- A filtering app: some services offer an App Store app that turns on their DNS filter for the whole phone. You may see a system prompt asking you to allow a DNS or VPN configuration.
- A configuration profile: some services let you download a profile, which you then review and install in the Settings app. Only install profiles from a provider you trust, because a profile can change how your phone connects to the internet.
- Your home router: some routers let you set a filtering DNS service for every device on your Wi-Fi. This only works while you’re connected to that network.
Things to weigh before you choose this route:
- It affects every app, not just Chrome. That can be good, but it can also break shopping links, email tracking links, or apps that rely on ad services.
- Results vary. DNS filtering can’t remove ads that come from the same address as the page content, so some ads will still show.
- Trust matters. Your DNS provider can see which sites your phone looks up. Read the provider’s privacy policy before you switch.
- Work or school phones may have management rules that block or override DNS changes. Ask your IT team before changing anything on a managed device.
Because setup steps differ by provider, follow the instructions from the service you pick, and keep a note of how to turn it off in case something stops working.
Which Option Should You Use?
| Option | Works in Chrome? | Blocks regular ads? | Effort | Best for |
|---|---|---|---|---|
| Chrome pop-up blocker | Yes | No, pop-ups only | Very low | Everyone; turn it on first |
| Chrome Safe Browsing | Yes | No, warns about dangerous sites | Very low | Avoiding scam and phishing pages |
| Safari content blocker | No, Safari only | Yes, most page ads | Low | People willing to browse in Safari |
| DNS filtering | Yes, and all apps | Partly | Medium to high | People who must stay in Chrome |
For most people, the best mix is simple: keep Chrome’s pop-up blocker and Safe Browsing on, and use Safari with a content blocker for ad-heavy sites. Try DNS filtering only if you’re comfortable troubleshooting network settings.
A quick decision guide:
- Mostly bothered by pop-ups and redirects? Method 1 plus Safe Browsing is often enough.
- Want clean pages and don’t mind switching browsers? Method 2.
- Need Chrome for everything and want fewer ads? Method 1 plus Method 3.
- Setting up a phone for a child or relative? Use Method 1 and Method 2, and pair them with Screen Time settings rather than network tricks you’ll need to maintain.
Workarounds to Avoid
You’ll find plenty of risky advice online about getting desktop ad blockers onto an iPhone. Skip these:
- Jailbreaking. Removing Apple’s security restrictions to install unofficial software weakens your phone’s protection, can stop updates from working, and isn’t worth it for ad blocking.
- “Chrome extension” apps for iPhone. Apps or websites claiming to add Chrome extensions to Chrome for iPhone aren’t adding real Chrome extensions. Treat them with suspicion.
- Unknown profiles and VPNs. Don’t install a configuration profile or VPN from a random website or pop-up ad. Only use providers with a clear privacy policy and a real App Store presence.
- Fake “your phone is infected” ads. These often push you to install an ad blocker or cleaner. Close the tab instead. Your iPhone doesn’t need a virus-cleaning app to fix a browser warning.
Troubleshooting
I can’t find Content Settings in Chrome
Make sure Chrome is up to date in the App Store, then look again under More and Settings. Scroll all the way down the Settings list. If the label has changed in a newer version, look for a section about site settings or pop-ups.
Pop-ups still appear with the blocker on
Some things that look like pop-ups are actually part of the page, such as newsletter sign-up boxes or cookie banners. Chrome’s pop-up blocker can’t stop those because they aren’t new windows. A Safari content blocker with an “annoyances” filter may help with them in Safari. Also check that you didn’t tap Always show for that site earlier.
My content blocker isn’t listed under Extensions
Open the blocker app once so it can finish setup, then check Settings, Apps, Safari, Extensions again. If it still doesn’t appear, restart your iPhone, or delete and reinstall the app. Make sure the app actually says it supports Safari content blocking.
The content blocker is on but Chrome still shows ads
That’s expected. Content blockers only affect Safari. To reduce ads in Chrome, use the pop-up blocker and consider DNS filtering.
A website broke after I turned on blocking
Blockers sometimes hide buttons, videos or checkout forms. Most content blocker apps let you allow a single site. You can also temporarily turn the blocker off in Settings, Apps, Safari, Extensions, complete your task, and turn it back on. If you use DNS filtering, pause it in the provider’s app.
A site says “please disable your ad blocker”
Many free sites rely on ads to pay for their content. You can allow that site in your blocker, subscribe, or leave. Don’t install extra tools to hide your blocker from a site.
Frequently Asked Questions
Does Chrome on iPhone have a built-in ad blocker?
Not a full one. Chrome for iPhone includes a pop-up blocker and Safe Browsing warnings, but it doesn’t remove standard ads from pages. Google’s separate setting for blocking ads on sites with intrusive ads is listed for computer and Android versions of Chrome, not for iPhone.
Can I install AdBlock or uBlock in Chrome on my iPhone?
No. Chrome for iPhone doesn’t support extensions, so desktop ad-blocking extensions can’t be installed in it. Some ad-blocking brands offer separate iPhone apps that work with Safari instead.
Will a Safari content blocker work in other apps?
Content blockers are designed for Safari. Some apps show web pages using Safari’s built-in viewer, and blocking may apply there, but you shouldn’t count on it. They don’t affect Chrome.
Is it safe to use an ad blocker on my iPhone?
Content blockers from reputable developers in the App Store are generally a safe choice, because Apple’s system limits what they can see. Be more careful with apps that use VPN or DNS settings, since they handle more of your traffic. Read the privacy details before you install.
Why do ads still show up after I block them?
No blocker catches every ad. Some ads are served from the same place as the page itself, and sites change their ad setups often. Keep your blocker app updated so its filter lists stay current.
Does blocking ads save data and battery?
It often can, because the phone skips downloading ad images, videos and scripts. How much you save depends on the sites you visit.
Summary
- Chrome for iPhone doesn’t support extensions, so you can’t add a traditional ad blocker to it.
- Turn on Block Pop-ups in Chrome under More, Settings, Content Settings.
- Set Safe Browsing to Standard or Enhanced protection for warnings about dangerous sites.
- For real ad blocking, install a Safari content blocker and turn it on in Settings, Apps, Safari, Extensions.
- If you must stay in Chrome, DNS filtering can reduce ads across the phone, but weigh the privacy and breakage trade-offs first.
Next step: open Chrome now and confirm Block Pop-ups is on, then decide whether you’d rather try a Safari content blocker for the sites where ads bother you most.
