What cookies are and why you might want to clear them
Cookies are small files that websites store on your computer to remember information about you — your login details, what's in your shopping cart, your language preference, or which ads you've seen. Most of the time they're useful. But they can also track your browsing across multiple sites, take up storage space, or cause a website to load an outdated version of itself when you visit again.
Clearing cookies means deleting these files from your device. You can clear all cookies at once, clear them for a specific time period, or delete cookies from just one website. The method depends on which browser you use and how selective you want to be.
Key Takeaways
- Clearing all cookies at once is the fastest option and works the same way in Chrome, Firefox, Safari, and Edge — look for "Clear browsing data" or "Clear history" in your browser settings.
- You can choose to clear cookies from just the last hour, day, week, or all time, which lets you keep cookies from sites you trust while removing older tracking data.
- Clearing cookies will log you out of most websites, so have your passwords ready or use a password manager before you clear.
- To clear cookies from one website only, you can usually right-click the site name in your address bar or find the site in your browser's storage settings.
- Cookies return immediately after you clear them — websites will start storing new ones as soon as you visit them again.
How to clear all cookies at once in Chrome
Open Chrome and click the three vertical dots in the top right corner. Select "Settings" from the menu. On the left side, click "Privacy and security," then click "Clear browsing data."
A window will pop up. At the top, choose your time range — "All time" clears everything, or pick "Last hour," "Last 24 hours," "Last 7 days," or "Last 4 weeks" to be more selective. Make sure the box next to "Cookies and other site data" is checked. Then click "Clear data." Chrome will close the window when it's done.
How to clear all cookies at once in Firefox
Open Firefox and click the three horizontal lines (the menu button) in the top right. Click "Settings," then select "Privacy & Security" on the left side. Under "Cookies and Site Data," click the "Clear Data" button.
A window appears. Make sure both "Cookies and Site Data" and "Cached Web Content" are checked if you want to clear everything. Click "Clear." If you want to clear cookies from only a specific time period, go back to the Privacy & Security page, find "History," and click "Clear Recent History" instead — that option lets you pick your time range.
How to clear all cookies at once in Safari
Open Safari and click "Safari" in the menu bar at the very top of your screen. Click "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 click individual websites to remove only their cookies, or click "Remove All" to clear everything at once. If you want to clear cookies from a specific time period, close this window and instead click "History" in the menu bar, then "Clear History" — you can choose to clear the last hour, today, today and yesterday, or all history.
How to clear all cookies at once in Microsoft Edge
Open Edge and click the three dots in the top right corner. Click "Settings," then select "Privacy, search, and services" on the left. Under "Clear browsing data," click "Choose what to clear."
A window opens. At the top, pick your time range — "All time," "Last hour," "Last 24 hours," "Last 7 days," or "Last 4 weeks." Check the box next to "Cookies and other site data." Click "Clear now." Edge will finish and close the window.
How to clear cookies from a single website
If you only want to remove cookies from one site without clearing everything, the method varies slightly by browser. In Chrome, Firefox, and Edge, click the lock icon or information icon next to the website address in your address bar. Look for "Cookies" or "Site settings," click it, find the website name, and click "Remove" or the trash icon next to it.
In Safari, go to "Safari" > "Settings" > "Privacy" > "Manage Website Data," search for the website name in the list, click it, and click "Remove." This approach is useful when a website isn't working properly and you suspect an old cookie is the problem, or when you want to remove tracking cookies from one site but keep your login information on others.
What happens after you clear cookies
You will be logged out of most websites immediately. The next time you visit a site that required a login, you'll need to enter your username and password again. If you use a password manager like Bitwarden, 1Password, or your browser's built-in password storage, this is usually automatic — the password manager will fill in your credentials for you.
Websites will start storing new cookies as soon as you visit them again. If you clear cookies regularly, you may notice websites loading more slowly the first time you visit them after clearing, because they have to rebuild your preferences and settings from scratch. Clearing cookies does not delete your browsing history, your saved passwords, or your autofill information unless you specifically check those boxes in the clear data window.
When clearing cookies actually helps
Clearing cookies can solve real problems in specific situations. If a website is showing you an old version of itself — an outdated price, a product that's out of stock, or a page layout from months ago — clearing that site's cookies often fixes it. If you're on a shared computer and want to remove your login information before someone else uses it, clearing cookies is one part of that (though you should also clear your browsing history and cached passwords).
Clearing cookies can also reduce the amount of tracking data stored on your device, though it's not a complete privacy solution. Websites can track you through other methods like browser fingerprinting or login accounts, and clearing cookies only removes the files themselves — it doesn't prevent new ones from being created. If privacy is your main concern, using your browser's private or incognito mode, or adjusting your cookie settings to block third-party cookies, may be more effective than clearing them after the fact.
Frequently Asked Questions
Will clearing cookies delete my saved passwords?
No. Cookies and saved passwords are stored separately. Clearing cookies will not affect your saved passwords unless you specifically check the "Passwords" box in the clear data window. Most people should leave that box unchecked.
What's the difference between clearing cookies and clearing browsing history?
Browsing history is the list of websites you've visited. Cookies are files websites store on your device. You can clear one without clearing the other. Most browsers let you choose which data to clear in the same window.
Do I need to clear cookies regularly?
Not unless you have a specific reason — a website not working properly, privacy concerns, or a shared device. Clearing cookies frequently can make websites slower to load and will log you out of accounts. If you're concerned about tracking, blocking third-party cookies in your browser settings is usually more practical than clearing them regularly.
Can I clear cookies from just one time period, like the last week?
Yes. When you open the "Clear browsing data" or "Clear history" window, the time range dropdown is usually at the top. Select "Last 7 days" or whichever period you want, and only cookies from that time will be removed.
Why does a website keep asking me to accept cookies after I clear them?
Because the website stores a cookie to remember that you accepted its cookie policy. When you clear cookies, that record is deleted, so the website shows you the cookie notice again the next time you visit. This is normal and expected behavior.
