YeetDL

YeetDL makes it easy to download YouTube videos in up to 8K video quality, so the videos are downloaded in the quality the author uploaded to their YouTube page. You can of course reduce the quality and download the one that suits you best. It supports .mp4 or .avi formats. In addition to downloading the videos themselves, it allows you to automatically download entire playlists or save just the audio track to .mp3 .aac, .ogg files for listening.
