Best site to download videos from youtube

Need help, no matter what site you go to, sometimes you can download videos and sometimes not, and sometimes there are a lot of ads, can you recommend more sites?

Try this site: https://easytube.pro/

I really like it and haven't had any problems so far. Convenient, simple, just paste the link and upload the video. You can also upload audio, which is very convenient and you don't have to convert it yourself. I've been using it for a year already, so I recommend it.
