When you have an Instagram account and want to be able to download videos or photos, you can either use a video downloader or a program that will do the task for you. A video downloader is a software application that will basically act as your portal to the Instagram service. The main issue with using a program is that it may access your account without your permission. For us, we suggest using an online downloader like IGDownloader.com. The Instagram downloader is an online tool for saving anything off Instagram. It's quick and free to use and doesn't require any registration. It's your best bet when you want to back-up those moments to look at time and time again.
