The video is processed by your device: allow a few seconds for a format change, longer for compression.
Extracting a video's audio as WAV gives an uncompressed file, the one audio editing, mixing and transcription software expects. Handy to rework a voice, clean up a recording or sync a music track.

The formats
MP4
The universal video format. In H.264 with AAC audio, it plays on every phone, computer, TV and social network. It is the format to aim for when you do not know where the video will be watched.
WAV
The uncompressed audio format of studios and editing software. It keeps full quality, but one minute of audio weighs about ten megabytes, ten times more than an MP3.
Your files stay with you
The conversion runs in your browser, with your device's decoders. No file is uploaded, no copy is kept, and nobody but you sees your photos or videos. You can check it in the Network tab of your browser's developer tools: none of your files goes out.
Frequently asked questions
WAV or MP3?
WAV to rework the audio in software, it loses nothing. MP3 to listen or share, it is ten times lighter.
Is the WAV better quality than the video's audio?
It is identical: the WAV copies the decoded audio without compressing it again. It adds no quality that was not in the video.
Is the converter really free?
Yes, with no sign-up, no watermark and no limit on the number of files. The conversion runs on your device and costs us nothing, so there is nothing to charge you for.
Are my files sent anywhere?
No. They are read and converted in your browser, then saved straight to your device. No server receives them.
Is there a maximum size?
The limit is your device's memory. Photos and audio files go through without trouble; for a video of several gigabytes, a computer does better than a phone.
Does it work on a phone?
Yes, on iPhone and Android, in Safari, Chrome or Firefox. For video, an up-to-date browser is needed: it provides the decoders being used.
