9 best YouTube to WebM converters Recommended

With billions of videos shared on YouTube, it's obvious you may want to save some for offline playback. But there's a problem; YouTube doesn't allow viewers to save videos locally. Therefore, you have to find an app to convert YouTube to WebM. But why not MP4? Okay, WebM uses VP9/VP8 video codec and Opus/Vorbis audio codec, which offer better audiovisual quality than MP4's H.264 video codec and ACC audio codec. Even better, most modern media players support WebM playback. So, let's discover the best YouTube to WebM converter for offline and online use.
