Where to convert WebM?

Question

Audio

I don’t like that the webm format is opened by both the audio player and the video player, or rather, I don’t like the fact that this format contains both audio and video, and when you double-click the audio starts playing in the video player, or vice versa, the video - in audio. Therefore, the question is: in what format is it best to convert audio-webm, so that on the one hand the file does not turn out to be too heavy, on the other hand, the sound quality does not suffer.

In the good old mp3? But I heard that it is outdated and the volume of content in its format is decreasing every day.

Answer 1

i don't understand much but:
webm is container like mp4 mkv which contains audio+video
wiki:

Contains
VP8 (video)
VP9 (video)
Vorbis (audio)
Opus (audio)

these audio codecs can be stuffed into an ogg container without transcoding
MP3 vs AAC vs OGG Vorbis - what is the best way to reap audio rips today?
