Hi! In such cases, I use a special service. To download YouTube videos in MP3 format, I recommend using https://getmp3.one/ . Paste the video link, select MP3 as the format and download. This is the most convenient option. It's also very fast and easy. I recommend it!

If you want to watch and create high-quality content, such as photos and videos, I recommend a program that can open png files , edit them with precision, and enhance their quality effortlessly. It offers great tools and features to make your projects shine. With its user-friendly interface, even beginners can navigate it easily. Plus, it supports a wide range of formats, making it versatile for any creative task. 

 Honestly, I don't quite understand it. 

When you download, you download not a video but an audio file. But if I need a video, then it doesn't work. 

Of course, there is such a format as faceless https://gyre.pro/blog/how-to-create-a-faceless-youtube-channel  and maybe when converting such a video format to audio it will work. But not always. Still, I would like to hear more about such programs with which you can fish out a video file from YouTube.
