Allavsoft for Windows can be said to be the best paid online video and music download software I have ever used. Not only does it support more than 1,000 websites (even Spotify), it also has built-in video conversion and merging functions. It can convert many formats, and it also directly lists devices, such as iPhone and iPad. Even if you don’t know what format to convert, you can easily find the right option.
This lifetime-use version was originally priced at US$99.99, but currently foreign websites are offering a limited-time free promotion, and there is no need to fill in any personal information. It is highly recommended that you get it. You are not sure when it will end, so just be quick.

If it does not exist, just click on the right to paste the URL. The download quality is defaulted to the best, and the highest quality only supports 1080p, which is a pity. YouTube videos will be MP4 files after downloading. If you don’t need to convert, just click the download icon at the bottom right:
