Clearing cookies from Safari removes tracking data that websites store on your device
Safari stores cookies — small files that websites use to remember who you are, what you clicked, and what you bought. Clearing them erases that record. On Safari, you can clear all cookies at once or delete them for specific websites. The process takes under a minute and works the same way on Mac, iPhone, and iPad.
If you arrived here from the data broker removal guide, clearing cookies is one step in reducing what information about you stays on your device. Cookies are separate from what data brokers collect about you online — they live only on your computer or phone. Removing them prevents websites from using stored information to track you during future visits.
Key Takeaways
- Safari stores cookies in one location, and you can clear all of them or choose specific websites to remove.
- On Mac, go to Safari menu > Settings > Privacy, then click Manage Website Data and select Remove All.
- On iPhone or iPad, go to Settings > Safari > Clear History and Website Data, then choose what time period to clear.
- Clearing cookies will log you out of most websites, so you may need to sign back in afterward.
- Cookies return when ready when you visit websites again — clearing them is not permanent protection.
How to clear all cookies on Mac Safari
Open Safari and click the Safari menu in the top left corner of your screen. Select Settings (or Preferences on older versions). Click the Privacy tab at the top of the window.
Click the button labeled Manage Website Data. A list of websites and the data they have stored will appear. Click Remove All at the bottom right. Safari will ask you to confirm — click Remove Now. All cookies are now deleted from your Mac.
How to clear cookies on iPhone or iPad Safari
Open the Settings app on your device. Scroll down and tap Safari. Scroll to the bottom and tap Clear History and Website Data.
A menu will appear asking what time period to clear. Choose All time to remove all cookies, or select a shorter period like Last hour, Last day, or Last week if you only want to clear recent activity. Tap Clear History and Data to confirm. Your cookies are now removed.
What happens when you clear cookies
When you clear cookies, Safari removes the stored files that websites use to recognize you. You will be logged out of most accounts — Gmail, Facebook, banking sites, shopping sites, and others. The next time you visit these websites, you will need to sign in again.
Websites will also forget your preferences. If a site remembered that you prefer dark mode or had items in your shopping cart, that information disappears. Some websites may load slightly slower the first time you visit after clearing cookies because they have to rebuild your profile from scratch.
The difference between clearing cookies and browsing privately
Safari's Private Browsing mode prevents cookies from being stored in the first place. When you open a private window, Safari does not save cookies, browsing history, or autofill information. When you close the private window, nothing is stored.
Clearing cookies removes what has already been stored. Private Browsing is useful if you want to prevent storage before it happens — for example, if you are shopping on a public computer. Clearing cookies is useful if you have already been browsing normally and want to erase the record afterward.
Why cookies return after you clear them
Clearing cookies is not permanent. The moment you visit a website again, that website can create new cookies on your device. If you visit Amazon, Amazon creates a new cookie. If you visit Google, Google creates a new cookie. This happens automatically — you cannot prevent it without using Private Browsing or a browser extension.
This is why clearing cookies alone does not stop tracking. It removes the current record, but websites start building a new one when ready. If you want ongoing protection, consider using Private Browsing for sensitive activities or enabling Safari's Prevent Cross-Site Tracking option in Privacy settings, which limits how much data websites can share with each other.
Clearing cookies for one website instead of all websites
If you only want to remove cookies from a specific website, you can do that on Mac. Open Safari, go to Safari menu > Settings > Privacy, and click Manage Website Data. Find the website in the list, click it to select it, and click Remove. That website's cookies are deleted, but cookies from other sites remain.
On iPhone and iPad, you cannot selectively remove cookies for one website — you can only clear all cookies or all cookies from a specific time period. If you need to remove data from one site on mobile, you would have to clear all cookies and then sign back into the other sites you use.
Frequently Asked Questions
Will clearing cookies delete my passwords?
No. Cookies and passwords are stored separately in Safari. Clearing cookies will not affect your saved passwords. You will still be logged out because the cookie that proves you are signed in is deleted, but Safari will offer to fill in your password when you sign back in.
Do I need to clear cookies regularly?
Not necessarily. Clearing cookies occasionally reduces what information websites have about you, but it is not required for Safari to work properly. If you clear them once a month or once a week, that is enough for most people. If privacy is a priority, clearing them weekly or using Private Browsing for sensitive activities is more effective.
Will clearing cookies speed up Safari?
Slightly, but not noticeably. Cookies are very small files, so they do not take up much space or slow down your browser. Clearing them may free up a tiny amount of storage, but you will not see a meaningful speed improvement. If Safari is running slowly, the issue is usually something else, like too many open tabs or extensions.
Can websites tell that I cleared my cookies?
Not directly. Websites cannot see into your Safari settings or know what you do on your device. However, if you visit a website and your behavior suddenly changes — for example, you were logged in and now you are not — the website knows something happened. They cannot tell if you cleared cookies or just closed the app.
What is the difference between cookies and tracking pixels?
Cookies are files stored on your device that websites can read. Tracking pixels are tiny images embedded in websites and emails that send information back to the website owner when you view them. Clearing cookies removes cookies but not tracking pixels. Safari's Prevent Cross-Site Tracking setting limits pixel tracking across websites.
