Good to know
MP4 is the most common video format. It contains both picture and sound, so if you only need the sound, the audio track can be pulled out and saved as a music file.
WAV stores audio uncompressed. There is zero quality loss, which is why editors and studios use it, but it takes roughly 10 MB per minute.
Extracts the sound of a video as uncompressed WAV — ideal for video editing, subtitling or audio analysis where you need the sound untouched.
Conversion runs inside this browser and files are never sent over the internet. Because your phone or computer does the work, long videos may take a little while.
FAQ
The WAV file is huge.
WAV is uncompressed at about 10 MB per minute. If you just want to listen or share, save as MP3 instead.
Are my files uploaded?
No. Every conversion runs in your browser on your own device.
Does it work with long videos?
Yes, but it uses your device’s power, so a one-hour video may take a few minutes, and files over 2 GB may fail on phones.
