Select cookies to clean with CCleaner for Windows

Using CCleaner Professional to clean web browser cookies:

This page covers what web browser cookies are, what they mean for you, how CCleaner manages them, and more. For specific instructions, start reading from How to manage cookies on your PC with CCleaner further down this page. 

What cookies are:

A cookie is a small file that a website can place on your hard drive.

What cookies do:

They contain information about when you visited the site, can often hold useful information such as your login token or shopping cart, saved work, saved games, and may contain tracking and settings information. For more information about cookies, see the Wikipedia entry.

CCleaner and different types of cookies:

Flash cookies (which are used by Adobe Flash) are cleaned differently by CCleaner. See this topic for more information on Flash cookies.

How deleting cookies can impact your website login data: 

You may choose to delete cookies for privacy reasons. Be aware, though, that some sites may forget your login data if you delete their cookies, requiring you to log in again, or may lose other saved data. Others will simply replace the cookie the next time you visit.

How CCleaner manages and cleans cookies: 

By default, when you run the Cleaner, CCleaner deletes all of the cookies for all of your Web browsers (Internet Explorer, Mozilla Firefox, Opera, and so on) except those in the Cookies to Keep column, which can be found in the Options > Cookies section of the program.

CCleaner doesn't clean the Cookies to Keep column by default:

There are 2 main reasons why CCleaner does this.

1. The cookies are from a frequently used website:

Deleting these cookies might mean you are logged out of the websites you use most, such as Facebook.

2. The cookies are needed to improve your experience:

CCleaner Free users may sometimes be shown contextual offers (for example, to install Google Chrome or Avast antivirus). So that only relevant offers are displayed, a cookie is stored on the user’s machine. To ensure that users are only ever shown a relevant offer, CCleaner will always try to keep or replace these cookies.

Note: Deleting these cookies might mean that you see offers more often than intended because the cookie that records offer display frequency has been removed during cleaning.

How to manage cookies on your PC with CCleaner:

Option 1: To keep all cookies on your PC

  1. In CCleaner, click the Custom Clean icon on the left.
  2. On the Windows tab, under Microsoft Edge, Edge Chromium, and/or Internet Explorer, clear the Cookies checkbox.
  3. If you have no other Web browsers installed, you have finished. If not, click the Applications tab.
  4. Under each browser listed, clear the Cookies checkbox.

Note: From this point on, whenever you run Custom Clean, it will retain all cookies from these browsers.

Option 2: To keep certain cookies on your PC

  1. In CCleaner, click the Options icon on the left.
  2. Click the Cookies button. The list may take a few seconds to load. You’ll now see a list of cookies from all the browsers you have installed on your system. The left column displays all cookies available to clean and the right column displays a list of Cookies to Keep.
  3. To keep cookies, move them to the Cookies to Keep column by selecting cookies and clicking the right-arrow button. You can select multiple cookies by using CTRL+click, or select a set of cookies in a row by clicking the first one and then SHIFT+ clicking the last one.

Option 3: To delete certain cookies on your PC manually

  1. In CCleaner, click the Options icon on the left.
  2. Click the Cookies button. The list may take a few seconds to load. This list displays cookies from all the browsers you have installed on your system.
  3. To remove a specific cookie, right-click on it and select Delete now. This can also be done for multiple cookies by using CTRL+click, or select a set of cookies in a row by clicking the first one and then SHIFT+clicking the last one.

Adding websites to 'Cookies to Keep' with Intelligent Cookie Scan:

CCleaner’s Intelligent Cookie Scan helps you by adding some popular websites to the Cookies to Keep list (if they are found on your computer when the scan is performed). The Cookies to Keep list stops you from being logged out of websites like Facebook and Twitter, or email providers like Gmail and Yahoo.

How to use Intelligent Cookie Scan:

  1. In CCleaner, click the Options icon on the left.
  2. Click the Cookies button. The list may take a few seconds to load. This list displays cookies from all the browsers you have installed on your system.
  3. To keep the cookies that store login data for the websites you use (for example webmail) right-click on the Cookies to Delete column and choose Intelligent Scan from the menu list.
  4.  A dialog box for the Intelligent Cookie Scan will appear and ask you to allow CCleaner to keep your persistent logins for websites. Selecting No cancels the operation. Selecting Yes (recommended) keeps all logins for websites and all available cookies from the Intelligent Cookie Scan list appear on the Cookies to Keep list.

Notes:

  • CCleaner Free users may sometimes be shown contextual offers. (For example, to install Google Chrome or Avast antivirus). So that only relevant offers are displayed, a cookie is stored on the user’s machine. CCleaner will always try to keep or replace these cookies because deleting them might mean that you see offers more often than intended (because the cookie that records offer display frequency has been removed during cleaning).
  • If you use the method in Option 1 to keep all cookies on your PC, the cookies in the Cookies to Delete column will not be deleted.
  • If you have a long list of cookies, you can search through them for the ones you want. Click inside the Search box and type a few letters in the cookie's domain name. For example, typing HOO will return cookies for Yahoo.com.
  • If you want to add a domain entry that hasn't appeared on your PC yet, right-click a blank part of the Cookies to Keep list, and then click Add. Type the domain name in the dialog box and then click OK.
