Where to find and delete cookies on iPhone
On iPhone, you delete cookies through the Settings app, not through your web browser itself. Open Settings, scroll down and tap Safari (or whichever browser you use — Chrome, Firefox, or Edge), then tap "Clear History and Website Data." A menu appears with options for what to clear: choose "Cookies and Site Data" or leave all options checked, then tap "Clear History and Data" at the bottom. The browser will delete the cookies immediately.
The exact path depends on your browser. For Safari, it's Settings > Safari > Clear History and Website Data. For Chrome, it's Settings > Apps > Chrome > Storage > Clear Cache (though Chrome calls them "cookies and site data" rather than cookies alone). For Firefox, it's Settings > Apps > Firefox > Storage > Clear Data. Each browser stores this setting in a slightly different place, but they all live in the Settings app rather than in the browser itself.
You can also set your browser to delete cookies automatically every time you close it. In Safari, go to Settings > Safari and toggle on "Privacy-Preserving Ad Measurement" or look for "Clear History and Website Data" options. Some browsers offer a "Clear on Exit" toggle that does this for you without manual steps each time.
Key Takeaways
- iPhone cookies are deleted through Settings, not through the browser app — go to Settings > Safari (or your browser name) > Clear History and Website Data.
- You can choose to clear only cookies and site data, or clear history, cookies, and cached images all at once.
- Deleting cookies will sign you out of most websites and remove saved preferences like language or font size.
- You can set most iPhone browsers to clear cookies automatically when you close the app, so you do not have to do it manually.
What cookies do and why you might delete them
Cookies are small files that websites store on your phone to remember information about you — your login status, items in your shopping cart, your language preference, or tracking data for ads. When you delete cookies, you erase that stored information. The next time you visit a website, it will not remember you were there before.
Most people delete cookies for privacy reasons: to remove tracking data that advertisers use to follow your browsing across websites, or to clear login information if you share your phone with someone else. Deleting cookies also frees up a small amount of storage space, though the amount is usually negligible on modern iPhones.
The downside is that deleting cookies also removes convenience features. You will be logged out of email, social media, banking apps, and shopping sites. Websites will forget your preferences — your preferred language, font size, or dark mode setting. You may see more generic ads instead of targeted ones, which some people prefer but others find less useful.
The difference between clearing cookies and clearing cache
When you tap "Clear History and Website Data" on iPhone, you are usually clearing three things at once: browsing history, cookies, and cached images and files. Cache is different from cookies — it is the images, videos, and code that websites store on your phone so they load faster the next time you visit. Cookies are the data files that remember information about you.
If you only want to delete cookies and not your browsing history, most iPhone browsers do not give you a granular option in Settings. Safari, Chrome, and Firefox all bundle these together. The workaround is to use the browser's own settings if available — some browsers have an in-app privacy menu that lets you choose what to clear — but on iPhone, the Settings app is the main control point.
Clearing cache makes websites load slightly slower the first time you visit them after clearing, because the browser has to download images and code again instead of using the stored versions. Clearing cookies does not affect loading speed but does log you out of websites and removes saved preferences.
How to delete cookies from specific websites only
iPhone does not have a built-in way to delete cookies from one website while keeping cookies from others. When you clear cookies, you clear all of them at once. If you want to remove cookies from a single site — say, to log out of a website you share with someone else — you have two options.
The first option is to visit that website in your browser, find the logout button, and click it. This removes your login cookie for that site without touching cookies from other websites. Most websites have a logout option in a menu or settings page. The second option is to clear all cookies and then log back into the sites you want to stay logged into. This takes more time but is more thorough if you are concerned about privacy.
Some browsers like Firefox offer a "Manage Cookies" feature that shows you a list of all cookies stored on your phone and lets you delete them one by one, but this feature is not available in Safari or Chrome on iPhone. If fine-grained cookie control matters to you, Firefox is the better choice.
Automatic cookie deletion and privacy settings
Most iPhone browsers let you set them to delete cookies automatically when you close the app. In Safari, go to Settings > Safari and look for options related to privacy or clearing data on exit. In Chrome, go to Settings > Privacy and turn on "Clear Browsing Data" or a similar toggle. In Firefox, go to Settings > Privacy and choose "Delete browsing data on quit."
When you enable this setting, the browser deletes cookies, history, and cached data every time you fully close the app — not just when you switch to another app, but when you swipe it away from the app switcher or it times out. This means you start each browsing session with a clean slate, which improves privacy but also means you will be logged out of websites every time you close the browser.
You can also increase privacy without deleting cookies by enabling "Private Browsing" or "Incognito Mode" in your browser. In Safari, swipe up from the bottom and tap "Private" to open a private tab. In Chrome, tap the menu and select "New Incognito Tab." Private browsing does not store cookies, history, or cache at all — they disappear as soon as you close the tab. This is useful for one-time browsing or when you want to log into a different account on the same website.
What happens after you delete cookies
After you delete cookies, you will be logged out of most websites. The next time you visit Gmail, Facebook, your bank, or any other site that requires a login, you will need to enter your username and password again. Websites will also forget your preferences — if you had set a site to dark mode or a specific language, it will revert to the default.
Some websites may load slightly slower the first time you visit them after clearing cookies, because they have to download images and code again instead of using cached versions. This slowdown is usually not noticeable on modern iPhones with fast internet, but it can add up if you clear cookies frequently and visit many sites.
Targeted ads may also change. If you delete cookies, advertisers lose the tracking data they use to show you ads based on your browsing history. You may see more generic ads instead, or ads based only on your current search or the content of the page you are viewing. Some people prefer this, while others find generic ads less relevant.
Frequently Asked Questions
Will deleting cookies delete my passwords?
No. Cookies and saved passwords are stored separately on iPhone. Deleting cookies will not remove passwords you have saved in Safari or your browser. You will still be able to use autofill to log back into websites, even after clearing cookies. If you want to delete saved passwords, you have to do that separately in Settings > Passwords (or Settings > [Browser Name] > Passwords, depending on which browser you use).
Do I need to delete cookies regularly?
Not necessarily. Cookies take up very little storage space on modern iPhones, so clearing them for storage reasons is not urgent. If privacy is your concern, clearing cookies once a month or enabling automatic deletion on exit is reasonable. If you share your iPhone with others, clearing cookies before handing it over prevents them from accessing your logged-in accounts.
Why am I still seeing targeted ads after deleting cookies?
Websites and advertisers track you in multiple ways beyond cookies. They use your IP address, device fingerprinting, and data from your accounts (like your Google or Facebook profile). Deleting cookies removes one tracking method but not all of them. To reduce targeted ads more broadly, turn on "App Tracking Transparency" in Settings > Privacy and disable tracking for individual apps.
Can I delete cookies from just one browser and keep them in others?
Yes. Each browser on iPhone stores its own cookies separately. If you use both Safari and Chrome, clearing cookies in Safari does not affect Chrome's cookies, and vice versa. You can clear cookies in one browser while leaving them in another by going to that specific browser's settings in the Settings app.
What is the difference between clearing cookies and using Private Browsing?
Clearing cookies removes cookies you have already stored. Private Browsing prevents cookies from being stored in the first place — when you close a private tab, nothing is saved. Private Browsing is useful for one-time browsing or logging into a different account, while clearing cookies is useful for removing tracking data after you have already browsed normally.
