IG Story Downloader is a third-platform tool that allows you to download Instagram stories of other users to your device. They typically work by requesting the username or link to the Instagram profile whose stories you want to save. Once provided, the downloader retrieves the stories and makes them available for download. Instagram story downloaders can come in the form of apps, as well as desktop versions, and only work with the accounts that are public. Some offer additional features like highlight and profile downloads, as well as bulk downloads.
