You would need to have Instagram installed on your smartphone or tablet, but don’t need to log in to save pictures using QuickSave.
 
Instagram doesn’t allow its users to save photos to their devices but QuickSave can download these files, but it won’t let you pick the destination folder unless you purchase the premium version.
 
You simply need to open Instagram and copy the post’s URL to QuickSave to download the image on your smartphone.
 
Pictures can be deleted from the download list by simply swiping the image left or right. The app also comes with a shortcut to Instagram. The app won’t be able to download private posts and it cannot be used for posting images to Instagram.
