What Are Cookies?

Cookies are tiny text files that a web server places on your computer when you visit a web page. The file is just letters and numbers, it doesn't run software code. When used by a website, the cookie can help make a webpage more user-friendly, for example by remembering your settings.

Cookies live in the memory of your web browser. Usually, a cookie contains:

  • The name of the server that created the cookie
  • A length of time the cookie will exist
  • A value (typically, a random string of numbers and characters)

Only the webpage that created the cookie can read it. Cookies can be used for a wide range of reasons. On BuzzFeed.com, we use cookies to anonymously track site usage, keep track of sessions and settings, improve website performance and administer services to users and advertisers.
