To the dismay of people all over the world, Instagram does not allow us to upload photos or videos to our profiles from your desktop or laptop. This is an intentional move from Instagram to encourage mobile use of the app and engagement with other users
Yes, you can use a PC to publish to Instagram, but there are certain restrictions. Instagram's desktop version only allows you to upload photos and videos to your profile. From the browser version, you won't be posting Instagram Photos, IGTV posts, or Reels. You also won't be able to start a Live video. Follow these simple steps to publish to Instagram on your desktop pc (PC or Mac): Sign in to your Instagram account at instagram.com. In the upper right corner of the screen, click the + sign (it's the same icon you'd use to make a post in the smartphone device). A The window for creating a new post will appear.
