What happens when you delete cookies?

What usually changes

• You may be signed out of websites.
• Language, region, display, and consent preferences may reset.
• Shopping carts stored only in the browser may be emptied.
• A website may treat the next visit as a new browser.
• Some broken sign-in or preference states may be fixed.

The effect depends on what each website stored in its cookies or related site storage.

What usually stays

• Your website accounts are not deleted.
• Bookmarks and downloaded files remain.
• Saved passwords remain unless you select their separate deletion category.
• Files already uploaded to a website remain in that account.
• Data the service keeps on its servers is not erased by deleting a local cookie.

Clear one site or everything?

Start with one site when troubleshooting. It preserves sessions and preferences elsewhere. Clear all cookies when you deliberately want a broad reset and are prepared to sign in again.

Our guides cover Chrome, Safari, Firefox, and Microsoft Edge.

Does deletion stop tracking?

It removes identifiers stored in the selected browser data, which can break continuity with earlier visits. A site can set new cookies when you return. Signed-in activity, device or network signals, and other storage technologies can still connect activity.

For an ongoing setting, review third-party-cookie and tracking protection.

Does deletion secure a compromised account?

Not by itself. If someone copied a valid session cookie, deleting your local copy may not invalidate theirs. Use the service’s sign-out-all-sessions or device controls, secure the account, and address the compromised device. See what to do about cookie theft.
