How to lock Google SafeSearch on iPhone and hide adult images

Set Google SafeSearch to Filter: in the Google app, tap your profile picture › Settings › SafeSearch; in Safari, open Google’s SafeSearch settings. Filter “blocks all explicit results”, including images, and is Google’s default when its systems indicate you may be under 18. Google documents only a few ways to lock it: a parent’s Family Link supervision, a school account, or the device or network, and Family Link can’t enforce it when the child isn’t signed in. Apple’s Limit Adult Websites and The Blocker block adult websites; neither filters the image results shown inside Google.

Written by the developer of The Blocker, which does not filter search results. Facts checked 22 October 2026 against Google Search Help, Google Family Link Help and Apple’s guides. Google says SafeSearch settings vary by country or territory. The Blocker is not affiliated with Google.

What SafeSearch does

Level	What Google says it does	Default for
Filter	“Blocks all explicit results.”	When Google’s systems indicate you may be under 18; children signed in to a Family Link account, or under 13
Blur	“Blurs explicit images”, but “explicit text and links can show if they’re relevant for your search”	Everyone else
Off	“Shows all results, which may include explicit content.”	Only if you choose it

Google’s own limit comes first: “SafeSearch only works on Google Search. It doesn’t affect content on other search engines or websites.” (Google)

Turn on Filter on iPhone

Google app: Google app › profile picture › Settings › SafeSearch › Filter.
Safari or another browser: go to google.com/safesearch and choose Filter.

Stay signed in. Google warns: “If you delete your cookies and you’re not signed in to your Google Account: Your SafeSearch setting could reset.” Signing in saves it “on all your devices” (Google).

This is a setting, not a lock. Google says: “If you manage your own Google Account, you can change Safesearch settings.” If you see a lock at the top right of the settings page, someone else manages it, and “the settings page provides info about who manages your SafeSearch setting” (Google).

The ways Google lets you lock it

Google lists who can lock SafeSearch: parents, schools, some public Wi-Fi networks, and “administrators of your device or network” (Google). On an iPhone that comes down to these:

Family Link, for a child’s Google Account. “SafeSearch filtering is turned on and locked by default for your child’s account,” and only parents can change it. But Google adds that it “can’t be enforced if: Your child isn’t signed into their Google Account” (Google). On an iPhone, a signed-out browser is easy to open, so pair it with Apple’s Screen Time.
A school account. The school’s administrator sets it.
Your home network. Whoever manages the router can force SafeSearch “for all browsers and devices using your network”, which “can’t be undone at the browser level”, by pointing www.google.com (and any local Google domains) at forcesafesearch.google.com in the network’s DNS. It covers Google Search, Image search and Video search (Google). It works only while the iPhone uses that network.
A DNS filter on the iPhone. CleanBrowsing says its free Family and Adult filters set Google and Bing to SafeSearch, and they apply to the whole device through an app or profile while it is on (CleanBrowsing). The Blocker has no DNS or VPN filtering, so this would be a separate tool.

Google’s device method, editing a hosts file, is for “Chromebooks, Windows, Mac, and Linux”; Google doesn’t list iPhone (Google).

Does Screen Time lock SafeSearch?

Apple doesn’t say so. Its pages on Limit Adult Websites don’t mention SafeSearch, and Google’s SafeSearch help doesn’t mention Apple or Screen Time. Google does list “family safety settings” and “your internet browser’s safety setting” among the things that can lock SafeSearch, without naming any (Google).

What Apple documents is narrower: Limit Adult Websites “limits access to many adult websites automatically” (Apple), and you can add your own sites under Never Allow (Apple). It decides which websites load. Google Search isn’t an adult website, and Apple doesn’t say its filter changes what Google shows on its results page. More in what Limit Adult Websites blocks.

Check your own phone: with your Screen Time settings on, open google.com/safesearch in Safari and look for the lock at the top right. If there is one, Google’s page tells you who manages the setting.

What The Blocker does here, and what it doesn’t

Plainly: The Blocker doesn’t filter search results. It has no Google setting, and it can’t hide image results or previews shown on google.com, because those come from Google itself. What it does is block adult websites:

Free, in Safari: the Adult category blocks sites whose names contain adult keywords, plus up to 10 sites you add. If you tap through from a result to such a site, the page is blocked. Keyword matching can miss adult sites whose names don’t contain those words.
Strong protection (Pro): Apple’s adult filter plus up to 50 of your own sites, in every browser and in links you open inside apps (the app names Instagram and X; test the Google app on your phone). Blocked apps can keep the Google app closed if you’d rather search in Safari with SafeSearch on Filter.

So the two do different jobs. SafeSearch cleans up Google’s results page; Limit Adult Websites, The Blocker and Strong protection stop the websites behind the results. You want both.

A setup that holds up

SafeSearch on Filter, signed in, in the Google app and in each browser you use.
Limit Adult Websites on, with a Screen Time passcode held by someone you trust. See free ways to block porn on iPhone.
The Blocker in Safari for free; Strong protection for other browsers and links inside apps. Pro is $4.99 a month, $29.99 a year or $49.99 once (US prices; the App Store shows your local price).
Delete browsers and search apps you don’t need, then restrict installing apps in Settings › Screen Time › Content & Privacy Restrictions › iTunes & App Store Purchases (Apple).
For a child: Family Link supervision for Google, Apple’s family controls for the iPhone, and the router lock at home if you manage it. See blocking porn on a child’s iPhone.

What SafeSearch can’t do

It works only on Google Search, not other search engines or websites.
Google says SafeSearch “tries to filter out inappropriate content”, and that it “isn’t designed to filter explicit content that has significant artistic, educational, historical, documentary, or scientific value.” If something slips through, report it to Google (Google).
Whoever manages the Google Account can change it, and a signed-out browser can bring back the default.

Questions people ask

How do I lock SafeSearch on my iPhone?

On your own account you can turn it on but not lock it: Google says that if you manage your own Google Account, you can change it. Google documents locks through Family Link (a parent), a school account, or a device or network administrator. On iPhone, the practical locks are Family Link for a child, a DNS setting on your home router, or a DNS filter app.

Why is SafeSearch locked on my iPhone?

Google lists the reasons: a parent using Family Link, a school, a public Wi-Fi network, your device or internet (including family safety settings and antivirus programs), or a browser safety setting that uses a URL parameter like safe=active. The SafeSearch settings page tells you who manages it.

Does Screen Time turn on Google SafeSearch?

Apple doesn’t document that, and Google’s help doesn’t mention Screen Time. Check on your phone: open google.com/safesearch in Safari and look for a lock at the top right.

Does The Blocker block adult images in Google search?

No. It blocks adult websites, not results inside google.com. Use SafeSearch on Filter for the results page, and The Blocker or Strong protection for the sites behind the results.

Is SafeSearch on by default for under-18s?

Google sets Filter by default when its systems indicate you may be under 18, and for children signed in to a Family Link account or under 13 (or the age in your country), where only parents can change it. Google’s help doesn’t say it is locked for a teen who manages their own account.
