What to expect
- Supported inputs
- MP4 videos and other readable video or audio files.
- What happens
- The video track is dropped and the audio is written as uncompressed PCM in a WAV file. WAV is selected first; you can choose another audio format.
- Limits
- The MP4 needs an audio track. WAV files are much larger than the MP4's compressed audio, roughly 10 MB per minute of stereo sound.
Your files stay on your device
Your computer does the work, so the file never has to be uploaded, and that’s also why it’s free: there’s no server time for us to pay for. You don’t need an account, and nothing you make gets a watermark.
