Download your data

1. Open Instagram and go to your profile, then the menu (three lines), then Accounts Center.
2. Tap Your information and permissions, then Download your information.
3. Choose Some of your information and pick what you need (for example Followers and following, and your posts), or choose All available information.
4. Choose All time, pick JSON (for moving data) or HTML (for reading it), and submit the request.
5. Instagram notifies you when the file is ready. Download the ZIP and save it in two places.

What you get: Your posts, captions, comments and messages, plus lists of followers and accounts you follow.

What you can't take: Followers come as usernames only. You get no email addresses, so the list can't be used to contact anyone.
