What cookies are and why you might want to delete them

Cookies are small files that websites store on your computer to remember things about you — your login information, items in your shopping cart, your language preference, or which ads you have seen. When you visit a website again, it reads those cookies to pick up where you left off.

Most cookies are harmless. But some track your browsing across many websites to build a profile of your interests, and some can slow down your browser if they accumulate over time. Clearing them is a straightforward way to reset your browsing history with a site, log out of accounts, or remove tracking data.

Key Takeaways

  • You can clear cookies from the last hour, day, week, or all time — choose the timeframe that matches what you want to remove.
  • The fastest route is Settings > Privacy and Security > Clear Browsing Data, then check "Cookies and other site data" and click Clear Data.
  • Clearing cookies will log you out of most websites, so save any work before you do it.
  • If you want to keep cookies from certain sites while clearing the rest, you can protect them in your site settings before clearing.

The step-by-step process to clear all cookies

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 pop up with options for what to delete.

At the top of that window, you will see a dropdown menu that says "All time" or shows a timeframe like "Last hour" or "Last 7 days". Choose the timeframe you want. If you want to delete everything, leave it on All time.

Make sure the box next to Cookies and other site data is checked. You can also check Cached images and files if you want to free up storage space. Then click the blue Clear Data button. Chrome will delete the cookies when ready.

What happens after you clear cookies

You will be logged out of most websites. The next time you visit a site where you have an account, you will need to sign in again. Websites will also forget your preferences — if you had set a dark theme or a specific language, you may need to set it again.

Websites may also load slightly slower the first time you visit them after clearing cookies, because they no longer have cached data about your preferences. This slowdown is temporary and usually not noticeable.

How to protect cookies from specific websites

If you want to clear most cookies but keep yourself logged into one or two important sites, you can protect those sites before you clear. Open Chrome Settings, go to Privacy and Security, then click Cookies and other site data.

Under "Sites that can always use cookies," click Add and type the website address (for example, gmail.com or your bank's website). Chrome will keep cookies from those sites even when you clear everything else.

Clearing cookies automatically on exit

If you want Chrome to delete all cookies every time you close the browser, you can set that up in Settings. Go to Privacy and Security and toggle on Clear cookies and site data when you quit Chrome. After that, every time you close Chrome completely, all cookies will be removed automatically.

This is useful if you share a computer or use a public device and do not want websites to remember you. It does mean you will need to log in again the next time you open Chrome, even if you were just using it an hour earlier.

The difference between clearing cookies and clearing browsing history

Clearing cookies and clearing browsing history are two separate things. Cookies are the files websites store on your computer. Browsing history is the list of websites you have visited, which Chrome keeps in its own records.

You can clear one without clearing the other. If you only want to remove the list of sites you visited, uncheck "Cookies and other site data" and check "Browsing history" instead. If you want to clear both, check both boxes.

Frequently Asked Questions

Will clearing cookies delete my passwords?

No. Passwords are stored separately from cookies. If you want to delete saved passwords, you have to do that in a different place: Settings > Autofill and passwords > Passwords. Clearing cookies alone will not touch them.

Do I need to clear cookies regularly?

Not necessarily. Most people do not need to clear cookies often. You might clear them if a website is behaving strangely, if you want to remove tracking data, or if you share a computer with others. Otherwise, they do not harm your computer.

What if I clear cookies and a website stops working?

Some websites rely on cookies to function properly. If a site breaks after you clear cookies, try refreshing the page or logging in again. If it still does not work, the site may have a technical problem unrelated to your cookies.

Can I clear cookies from just one website?

Yes. Go to Settings > Privacy and Security > Cookies and other site data > All cookies and site data. Search for the website name and click the trash icon next to it. That removes only that site's cookies, not your cookies from everywhere else.

Does clearing cookies improve my privacy?

It removes some tracking data, but it is not a complete privacy solution. Websites can still track you through other methods like your IP address or browser fingerprinting. Clearing cookies helps, but using a private browsing window or a privacy-focused browser offers stronger protection.
