Deleting cookies removes the stored data that websites use to remember you
When you visit a website, it often stores small files called cookies on your computer. These files remember your login information, shopping cart contents, preferences, and browsing history. Deleting cookies clears this stored data. The steps differ slightly depending on which browser you use — Chrome, Firefox, Safari, or Edge — but the process takes less than a minute in any of them.
You might delete cookies to free up storage space, remove tracking data, or troubleshoot a website that is not working correctly. Deleting cookies will log you out of most websites, so you may need to sign back in afterward. Some sites will also forget your preferences until you visit them again.
Key Takeaways
- Chrome, Firefox, Safari, and Edge all let you delete cookies through their settings menu, usually under "Privacy" or "History".
- You can delete all cookies at once or choose a specific time range, such as the last hour or last 30 days.
- Deleting cookies will log you out of most websites and remove saved preferences like language or theme settings.
- You can also set your browser to delete cookies automatically every time you close it, if you prefer not to do it manually.
How to delete cookies in Google Chrome
Open Chrome and click the three vertical dots in the top right corner. Select Settings from the menu that appears. On the left side, click Privacy and security, then click Clear browsing data.
A window will open with several options. Make sure the box next to Cookies and other site data is checked. At the top, choose the time range you want to clear — you can select All time to delete everything, or pick a specific range like Last hour, Last 24 hours, Last 7 days, Last 4 weeks, or Last 30 days. Then click Clear data.
How to delete cookies in Mozilla Firefox
Open Firefox and click the three horizontal lines in the top right corner. Select Settings from the menu. On the left side, click Privacy & Security. Under the Cookies and Site Data section, click Clear Data.
A small window will appear. Make sure Cookies and Site Data is checked. Click Clear to remove all cookies immediately. If you want to delete cookies from only a specific time period, you will need to use the keyboard shortcut Ctrl+Shift+Delete (or Cmd+Shift+Delete on Mac) to open the full history clearing tool, where you can choose a time range before clicking Clear Now.
How to delete cookies in Apple Safari
Open Safari and click Safari in the menu bar at the top of the screen. Select Settings (or Preferences on older versions). Click the Privacy tab. Click Manage Website Data to see all stored cookies and site data.
You can select individual websites and click Remove to delete cookies from just those sites, or click Remove All to delete everything at once. If you want a faster option, go back to the Privacy tab and look for the option to remove cookies when you quit Safari — this will delete them automatically every time you close the browser.
How to delete cookies in Microsoft Edge
Open Edge and click the three horizontal dots in the top right corner. Select Settings. On the left side, click Privacy, search, and services. Under Clear browsing data, click Choose what to clear.
A window will open. Make sure Cookies and other site data is checked. At the top, select your time range — All time, Last hour, Last 24 hours, Last 7 days, Last 4 weeks, or Last 30 days. Click Clear now to finish.
Setting your browser to delete cookies automatically
If you do not want to manually delete cookies each time, you can set most browsers to clear them automatically when you close the application. In Chrome, go to Settings > Privacy and security and toggle on Clear cookies and site data when you quit Chrome. In Firefox, go to Settings > Privacy & Security, scroll to Cookies and Site Data, and check the box next to Delete cookies and site data when Firefox is closed.
In Safari, click Safari > Settings > Privacy and check Remove all website data when quitting Safari. In Edge, go to Settings > Privacy, search, and services and toggle on Clear browsing data under the Clear browsing data section. With this setting enabled, your cookies will disappear every time you fully close the browser.
What happens after you delete cookies
After you delete cookies, you will be logged out of most websites. The next time you visit a site that required a login, you will need to enter your username and password again. Websites will also forget any preferences you had saved, such as your preferred language, theme color, or font size.
Some websites may load slightly slower the first time you visit after deleting cookies, because they need to re-download certain data. This is temporary and will not cause any lasting problems. If a website is not working correctly and you suspect cookies are the cause, deleting them is often a good troubleshooting step.
Frequently Asked Questions
Will deleting cookies delete my passwords?
No. Cookies and saved passwords are stored separately. When you delete cookies, your saved passwords remain in your browser's password manager. You can delete passwords separately if you want to, but the cookie deletion process does not touch them.
Can I delete cookies from just one website?
Yes. In Chrome, Firefox, and Edge, you can right-click on any website and select an option to clear data for that site only. In Safari, open Manage Website Data and select the specific website from the list, then click Remove.
What is the difference between deleting cookies and clearing browsing history?
Cookies are small data files websites store on your computer. Browsing history is the list of websites you have visited. Deleting cookies removes stored data from websites, while deleting history removes the record of which sites you visited. You can delete one without deleting the other.
Will deleting cookies speed up my browser?
Cookies take up very little storage space, so deleting them will not noticeably speed up your browser. If your browser is running slowly, the cause is usually something else, like too many open tabs or browser extensions. Deleting cookies may help if a specific website is malfunctioning, but it is not a general performance fix.
Do I need to delete cookies regularly?
No. Cookies do not harm your computer and do not need to be deleted on a schedule. You can delete them whenever you want — some people do it weekly, others only when a website stops working correctly. If privacy is a concern, you can set your browser to delete cookies automatically when you close it.
