What to expect
- Supported inputs
- MP4 videos, including phone videos and screen recordings, and other readable video or audio files.
- What happens
- The video track is dropped and the audio is encoded as MP3. MP3 is selected first; you can switch to WAV, M4A, or another audio format.
- Limits
- The MP4 needs an audio track. Very long videos depend on your device's memory.
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.
