How to export cookies from Chrome

For debugging a login, reproducing a bug, feeding curl or wget, or seeding an automated test. As JSON or Netscape cookies.txt.

Treat a cookie export like a password. Session cookies log whoever holds them in as you. Don't paste them into chats, issues or AI tools, don't commit them to git, and delete the file when you're done. Only export cookies of your own accounts.

1. The console: quick, but incomplete

Open DevTools (F12) → Console on the site and run:

copy(document.cookie)

This copies name=value; name2=value2 to your clipboard. The catch: document.cookie never includes HttpOnly cookies, and those are usually the session cookies you care about. It also drops each cookie's domain, path, expiry and flags. It's fine for a quick look, not for a working export. (I checked this: on a test page that sets an HttpOnly sid and a plain theme cookie, the console only returns theme=dark.)

2. DevTools Application panel: complete, but one site at a time

DevTools → Application → Storage → Cookies → pick the site. You see every cookie, including HttpOnly and partitioned ones, with all their fields, and you can edit or delete them. There's no export button. You can select and copy rows, but you'll have to reformat them by hand before a tool like curl can use them.

3. Playwright's storageState (for automation)

If you control the browser from code, for example in end-to-end tests, Playwright saves the cookies and localStorage of a browser context to JSON in one call, and can load them again later:

// after logging in within `context`
await context.storageState({ path: 'state.json' });   // cookies + localStorage
const cookies = await context.cookies();              // cookies only, incl. HttpOnly

// later: start already logged in
const context2 = await browser.newContext({ storageState: 'state.json' });

This covers the browser Playwright launched, not your everyday Chrome profile. It's the right tool for tests and scripts. I tested this snippet: HttpOnly cookies and localStorage are both included.

4. A cookie editor extension (your normal browser)

To export cookies from the browser you actually use, one site or all of them, a cookie editor extension is the practical way:

• Cookie Crate (made by me, see below): shows every cookie that applies to the current site, including parent-domain, HttpOnly and partitioned cookies. It exports them as JSON in the array format common cookie editors use, and imports that JSON or Netscape cookies.txt. It asks for access only to the site you open it on. Pro (€7 once) adds exporting and importing all sites at once, cookies.txt export, protected cookies and profiles.
• Other cookie editors do the same basic job. Whichever you pick, check its permissions and whether it makes network requests. A cookie tool that sends data off your machine is a serious risk.

Using an export with curl or wget

Both read the Netscape cookies.txt format:

curl -b cookies.txt https://example.com/account
wget --load-cookies cookies.txt https://example.com/file

In cookies.txt, HttpOnly cookies are written with a #HttpOnly_ prefix before the domain. curl understands it. Some older tools treat these lines as comments and skip them.
