What clearing cookies does and why you might want to
Clearing cookies removes the small files that websites store on your computer to remember who you are, what you've looked at, and what you've put in shopping carts. When you clear them, websites no longer have that record — you'll log out of accounts, sites won't remember your preferences, and advertisers lose some of the tracking data they use to follow you across the web.
Most people clear cookies to reduce tracking by ad networks, to log out of accounts on shared computers, or to free up a small amount of storage space. Clearing cookies won't stop your internet service provider or your employer from seeing what sites you visit, and it won't hide your activity from the websites themselves — it only removes the files those sites left behind on your device.
The process takes less than a minute and works the same way whether you use Chrome, Firefox, Safari, or Edge. You can clear all cookies at once or choose a date range, and you can set your browser to clear them automatically every time you close it.
Key Takeaways
- Clearing cookies logs you out of websites, removes stored preferences, and stops some ad tracking, but does not hide your browsing from your internet provider or employer.
- Every major browser has a built-in tool to clear cookies in one or two clicks, usually found under Settings or Preferences.
- You can clear all cookies at once or choose to clear only cookies from a specific date range or website.
- Setting your browser to clear cookies automatically when you close it removes tracking files without requiring manual action each time.
How to clear cookies in Chrome
Open Chrome and click the three vertical dots in the top right corner. Select Settings from the menu, then click Privacy and security in the left sidebar. Click Clear browsing data.
A window will appear with three tabs: Basic, Advanced, and On exit. Make sure Cookies and other site data is checked. At the top, choose your time range — All time clears everything, or you can pick Last hour, Last 24 hours, Last 7 days, Last 4 weeks, or Last 3 months. Click Clear data.
To clear cookies automatically every time you close Chrome, go back to Settings and Privacy and security. Under Clear browsing data, turn on Clear cookies and site data when you quit Chrome.
How to clear cookies in Firefox
Open Firefox and click the three horizontal lines in the top right corner. Select Settings, then click Privacy & Security in the left sidebar. Scroll down to Cookies and Site Data and click Clear Data.
A small window will appear. Make sure both Cookies and Site Data and Cached Web Content are checked, then click Clear. Firefox clears all cookies by default — there is no date range option in this quick menu. If you want to clear only cookies from a specific time period, click the menu button again, go to History, and select Clear Recent History instead, where you can choose your time range.
To clear cookies automatically, go back to Settings and Privacy & Security. Under Cookies and Site Data, check the box next to Delete cookies and site data when Firefox is closed.
How to clear cookies in Safari
Open Safari and click Safari in the top menu bar. Select Settings (or Preferences on older versions), then click the Privacy tab. Click Manage Website Data.
A list of websites and their stored data will appear. To clear all of it, click Remove All. To remove cookies from specific websites, select them from the list and click Remove. Click Done when finished.
Safari does not offer a built-in option to clear cookies on exit, but you can achieve the same result by going to Safari > Settings > Privacy and unchecking Allow privacy-preserving ad measurement and Allow cross-site tracking to reduce tracking overall.
How to clear cookies in Edge
Open Microsoft Edge and click the three dots in the top right corner. Select Settings, then click Privacy, search, and services in the left sidebar. Under Clear browsing data, click Choose what to clear.
A window will appear. Make sure Cookies and other site data is checked. At the top, choose your time range — All time, Last hour, Last 24 hours, Last 7 days, Last 4 weeks, or Last 3 months. Click Clear now.
To clear cookies automatically when you close Edge, go back to Settings and Privacy, search, and services. Scroll down to Clear browsing data and turn on Choose what to clear every time you close the browser. Edge will then ask you what to clear each time you close it.
Clearing cookies from specific websites
If you want to clear cookies from only one or two websites instead of everything, most browsers let you do that without clearing the rest. In Chrome, Firefox, and Edge, you can visit the website, click the lock icon or info icon next to the web address, find Cookies or Site data, and delete them from there.
In Safari, use the Manage Website Data option described above and select only the websites you want to remove. This approach is useful if you want to stay logged into most sites but log out of one specific account, or if you want to clear tracking cookies from ad networks without clearing your login information everywhere else.
What happens after you clear cookies
After clearing cookies, you will be logged out of most websites. The next time you visit a site, it will not remember your preferences — your language setting, dark mode choice, or saved items in a shopping cart will reset to defaults. Websites may also load slightly slower the first time you visit them after clearing, because they have to rebuild some of the data they normally store locally.
Advertisers will have a harder time tracking you across different websites, but this effect is temporary — they will start building a new profile as soon as you visit their sites again. Clearing cookies is not a substitute for using a private browsing window or a VPN if you want to hide your activity from your internet provider or network administrator.
Frequently Asked Questions
Will clearing cookies delete my passwords?
No. Passwords are stored separately from cookies. When you clear cookies, you will be logged out of websites, but your saved passwords remain in your browser's password manager. You can log back in using your saved credentials without re-entering them manually.
Can I clear cookies from just one website without clearing all of them?
Yes. In Chrome, Firefox, and Edge, click the lock or info icon next to the website address in your browser bar, find the option for cookies or site data, and delete them from there. In Safari, use the Manage Website Data menu and select only the websites you want to remove.
Does clearing cookies stop advertisers from tracking me?
It stops them temporarily. Clearing cookies removes the tracking files already on your device, but advertisers will start building a new profile as soon as you visit their sites again. For longer-term reduction in tracking, use your browser's privacy settings to block third-party cookies or enable tracking prevention.
What's the difference between clearing cookies and using private browsing?
Private browsing (Incognito in Chrome, Private Window in Firefox) prevents your browser from storing cookies in the first place — they are deleted when you close the window. Clearing cookies removes files that are already stored. Private browsing is useful for one-time visits; clearing cookies is useful for removing tracking data from regular browsing.
If I set my browser to clear cookies on exit, will I stay logged into websites?
No. If you set your browser to clear cookies when it closes, you will be logged out of all websites every time you shut down your browser. You will need to log back in the next time you visit. If you want to stay logged in, turn off automatic clearing and clear cookies manually when you choose to.
