The quality of YouTube Shorts that you can download depends on the quality of the original video uploaded by the creator. However, Shorts videos are designed to be short and lightweight, so they typically have a lower resolution compared to longer YouTube videos. As of now, Shorts videos are available in 720p HD resolution, which is still pretty good for such short videos. So, the quality of the Shorts video you can download will depend on the original resolution of the video uploaded by the creator.
