What is the best method for youtube to mov download?

There are several free and open-source desktop solutions that can download and convert YouTube videos in a single step, so you don’t necessarily need separate programs. Most of them work offline and don’t require browser extensions.

That said, I’d pay close attention to the legal side. Downloading your own YouTube videos or content that the creator has explicitly made available for download is generally fine. However, downloading copyrighted videos without permission may violate YouTube’s Terms of Service and, depending on your country’s copyright laws, could also be unlawful.

If you’re downloading videos for personal projects, make sure you have the creator’s permission or that the content is licensed for reuse. That’s the safest approach regardless of which software you choose.
