What cookies are and why you might want to delete them
Cookies are small files that websites store on your computer to remember information about you — your login details, items in a shopping cart, your preferred language, or sites you've visited. They make browsing faster and more convenient, but they also mean websites can track your activity across the internet.
Clearing cookies regularly can improve your privacy, free up storage space, and sometimes fix problems like being stuck logged into someone else's account. Most browsers let you delete cookies in just a few clicks, and you can choose to clear all of them at once or remove only the ones from specific websites.
Key Takeaways
- Cookies are stored files that websites use to remember your information, and clearing them improves privacy and can fix login problems.
- Every major browser — Chrome, Firefox, Safari, and Edge — has a built-in tool to delete cookies, usually found in Settings or Preferences under Privacy or History.
- You can clear all cookies at once or delete cookies from only certain websites, depending on what you need.
- Clearing cookies will log you out of most websites, so save any work before you start.
- You can set your browser to delete cookies automatically when you close it, so you don't have to do it manually each time.
How to clear cookies in Google Chrome
Open Chrome and click the three vertical dots in the top right corner. Select Settings from the menu, then click Privacy and security on the left side. Choose Clear browsing data or Delete browsing data.
A window will pop up with several options. Make sure the time range at the top is set to what you want — All time will delete everything, while Last hour, Last 24 hours, or Last 7 days will delete only recent cookies. Check the box next to Cookies and other site data, then click Clear data. The process takes a few seconds.
If you want to delete cookies from only one website, go back to Settings and choose Privacy and security, then Cookies and other site data. Search for the website name and click the trash icon next to it.
How to clear cookies in Mozilla Firefox
Click the three horizontal lines (hamburger menu) in the top right corner and select Settings. On the left, click Privacy & Security. Under the Cookies and Site Data section, click Clear Data.
A box will appear with two checkboxes. Make sure Cookies and Site Data is checked, then click Clear. If you want to choose a time range first, click the menu that says Everything at the top of the Settings page and select Last Hour, Last 24 Hours, Last 7 Days, or Last 3 Months. Then return to the Cookies and Site Data section and clear.
To remove cookies from a single site, go to Settings > Privacy & Security > Cookies and Site Data and click Manage Data. Type the website name in the search box, select it, and click Remove Selected.
How to clear cookies in Safari
Click Safari in the menu bar at the top of your screen, then select Settings (or Preferences on older Macs). Go to the Privacy tab. Click Manage Website Data to see all stored cookies and site data.
You can select individual websites and click Remove, or click Remove All to delete everything at once. If you want to clear cookies without seeing the list, close the Manage Website Data window, click the Privacy tab, and look for an option to clear history — select All history and make sure Cookies and cache is checked.
How to clear cookies in Microsoft Edge
Click the three dots in the top right corner and select Settings. On the left side, click Privacy, search, and services. Under Clear browsing data, click Choose what to clear.
A window will open. Set the time range using the dropdown at the top — All time clears everything, or choose a specific period. Check the box for Cookies and other site data and click Clear now. To delete cookies from just one website, go back to Privacy, search, and services, scroll to Clear browsing data, and click Manage what's cleared. Find the site and click the minus sign next to it.
Setting your browser to delete cookies automatically
If you want cookies deleted every time you close your browser, you can turn on this setting instead of clearing them manually. In Chrome, go to Settings > Privacy and security and toggle on Delete cookies and site data when you quit Chrome. In Firefox, go to Settings > Privacy & Security, find Cookies and Site Data, and check 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, scroll to Clear browsing data, and toggle on Choose what to clear every time you close the browser. Then click Manage what's cleared every time you close your browser and check Cookies and other site data.
What to expect after clearing cookies
After you clear cookies, you will be logged out of most websites. The next time you visit a site that requires a login, you'll need to enter your username and password again. Websites may also load slightly slower the first time you visit them, because they no longer have stored information about your preferences.
Some websites may ask you to accept cookies again or re-enter settings like your preferred language or region. This is normal and happens because the site no longer has the cookie file that stored those choices. If you clear cookies regularly, you may find yourself logging in more often, so consider clearing only cookies from sites you don't use frequently, or set a schedule like once a month instead of every time you browse.
Frequently Asked Questions
Will clearing cookies delete my passwords?
No. Cookies and saved passwords are stored separately. Clearing cookies will log you out of websites, but your saved passwords remain in your browser's password manager. You can clear cookies without touching passwords, or clear passwords separately if you want to remove both.
What's the difference between clearing cookies and clearing cache?
Cookies are small text files that store login information and preferences. Cache is a larger collection of images, scripts, and other files that websites read to make pages load faster. Clearing cache frees up more storage space but doesn't affect your privacy the same way. Most browsers let you clear them together or separately.
Can I delete cookies from just one website instead of all of them?
Yes. Every major browser has an option to remove cookies from specific sites. In Chrome, Firefox, Safari, and Edge, you can search for a website name in the cookies section and delete only that one. This is useful if you want to clear a login from one site but stay logged into others.
Do I need to clear cookies if I use private or incognito mode?
No. Private browsing mode (called Incognito in Chrome) doesn't store cookies or browsing history by default. When you close a private window, all cookies from that session are deleted automatically. You only need to clear cookies manually if you browse in normal mode.
Why does a website keep asking me to accept cookies after I clear them?
Websites are required by law in many countries to ask for permission before storing cookies. When you clear cookies, the site no longer has a record that you accepted, so it asks again. Accepting once more will store a new cookie with your preference, and the site won't ask again until you clear cookies a second time.
