The most widely recognized and least complex approach to repost a video to Instagram (outside of the local Stories include) is by utilizing an application like Repost or InstaRepost or Instagram Downloader.

For Instagram Downloader, it couldn't be simpler. What's more, we prescribe this one over a portion of different choices for three reasons:

It's a free web application, which implies it is stage skeptic (you can snatch the video on your workstation)

Since it downloads the video itself, you can then repost that video to Twitter and different systems like YouTube (with authorization)

You don't need to pursue a record

Step.1 Find the Video on Instagram
Step.2 Go to InstagramVideoDownloader.co and Paste the Link
