dhIMG Instagram is a free program that works on pretty much any computer running Microsoft Windows and allows you to download images and videos from an Instagram profile easily. This tool can be extremely handy if you are wanting to backup your Instagram profile and don't wish to save every image manually.
Even though this falls in the dhIMG family (for bulk image saving), the difference with this program is the option to also save any videos that have been uploaded to an (open/public) Instagram account.
Small program size
Standalone application (no need to install)
Quick downloading/backing up of Instagram images and Videos
