If your Instagram account is public, your content (e.g. post, reel, guide) or profile can be shared by third-party sources such as blogs and articles using an embed code. Embed codes allow your profile or content to be shared along with your username and a link to your Instagram profile.
Note that for a post or profile to be embedded, your account must be public and the Embeds setting must be turned on. Private accounts and content from private accounts cannot be embedded.
If you’d like to embed a public Instagram profile or content from a public Instagram account into your HTML editor, you can only copy the embed from Instagram.com.
