Turned my webinar into a podcast
Had hours of webinar recordings sitting in MP4. Cacao Docs extracted the audio in minutes and now they are live as podcast episodes. Absolute time saver.

No nonsense, just works
Tried three other sites before this. All garbage. Cacao Docs converted my MKV to MP3 instantly with zero fuss. Staying here.

Great for music producers
I pull stems and reference tracks from video files all the time. Cacao Docs is the fastest way to do it and the audio quality is spot on.
