Some Reels / posts require a logged-in Instagram session. Export your browser cookies, store them in this browser only, and downer will send them with each download request. Cookies never leave your machine.

1. Get your Instagram cookies

Easiest path: install a single extension, click once, copy. The exported file looks like the example below.

  1. Install Get cookies.txt LOCALLY in Chrome / Edge (or the Firefox equivalent).
  2. Click the icon → tick only .instagram.com → click Export → choose Netscape format. Save the file.
  3. Or, if you have yt-dlp installed:
    yt-dlp --cookies-from-browser chrome --skip-download https://www.instagram.com/
    yt-dlp will print the cookies file path; you can also pipe it directly:
    yt-dlp --cookies-from-browser chrome --skip-download --print cookies.txt https://www.instagram.com/ > instagram_cookies.txt
Open Instagram login in new tab

We do not log the cookie values, share them with third parties, or persist them server-side. To stop sending them, clear the field above or click "Clear".
