FAQ
Why can't I convert to MP3?
No browser ships an MP3 encoder. We'd have to download an extra encoder library, so instead we offer WAV (universal) and Opus/AAC where supported.
What's the best format for speech-to-text tools?
Mono, 16,000 Hz WAV is what most transcription engines expect, and it keeps files small.
Can I extract the audio from a video?
Yes — drop the video file in and convert it to WAV or Opus.
