HTTP Cookies are mainly used to manage user sessions, store user personalization preferences, and track user behavior. They are also the cause of all of those annoying "this page uses cookies" consent forms that you see across the web. This guide teaches you how to view, add, edit, and delete a page's cookies with Chrome DevTools.

Open the Cookies pane {: #open }

1. Open Chrome DevTools.
2. Open Application > Storage > Cookies and select an origin.

Fields {: #fields }

The Cookies table contains the following fields:

• Name. The cookie's name.
• Value. The cookie's value.
• Domain. The hosts that are allowed to receive the cookie.
• Path. The URL that must exist in the requested URL in order to send the Cookie header.
• Expires / Max-Age. The cookie's expiration date or maximum age. For session cookies this value is always Session.
• Size. The cookie's size, in bytes.
• HttpOnly. If true, this field indicates that the cookie should only be used over HTTP, and JavaScript modification is not allowed.
• Secure. If true, this field indicates that the cookie can only be sent to the server over a secure, HTTPS connection.
• SameSite. Contains Strict or Lax if the cookie is using the experimental SameSite attribute.
• Partition Key. For cookies with independent partition state, the partition key is the site of the top-level URL the browser was visiting at the start of the request to the endpoint that set the cookie.
• Priority. Contains Low, Medium (default), or High if using deprecated cookie Priority attribute.

To view a cookie's value, select it in the table. To see the value without percent-encoding, check {% Img src="image/NJdAV9UgKuN8AhoaPBquL7giZQo1/hmp8j3HiLMCcqPArD9yt.svg", alt="Checkbox.", width="22", height="22" %} Show URL-decoded.

Filter cookies {: #filter }

Use the Filter text box to filter cookies by Name or Value.

Filtering by other fields is not supported. Filter is case-insensitive.

Add a cookie {: #add-cookie }

To add an arbitrary cookie:

1. Double-click an empty row in the table.
2. Enter a Name and Value and press Enter.
