Users encounter a problem with the Peggo YouTube Downloader when it comes to optimizing downloaded videos for different devices. Although the tool allows them to download videos in high resolution, it does not offer functions to improve or adapt the video quality for different devices. Users may have difficulties when viewing videos on devices with different screen resolutions - the video may be either too large and therefore blurry on smaller screens, or it may be too small on larger screens. Since optimization cannot be easily performed manually, this causes frustration among users. Therefore, it is a significant problem that Peggo does not offer a way to adjust the video quality to different devices.

To solve the problem of missing video optimization for various devices, Peggo YouTube Downloader can introduce a feature for automatic adjustment of video quality. This smart feature recognizes the screen resolution of the target device and adjusts the video quality accordingly to ensure the best possible viewing experience. Neither too large nor too small videos are displayed on the devices. In addition, a manual slider could be implemented, allowing users to adjust the video resolution to their liking. This way, frustrating experiences are avoided and user satisfaction is increased. Such an optimization feature greatly enhances the versatility and usefulness of Peggo, making it a true all-in-one tool for downloading and watching YouTube videos on various devices.
