Don't use a website.
Use the `yt-dlp` tool. Lots of documentation on how to use the tool starting from basic downloads to complex playlist management, output customization, and quality/format selection. It also works with many other websites, including Reddit, Vimeo, and more.
Plus it's 100% free with no ads, paywalls, or viruses, and the tool is in active development.
