How to convert MP4 to WAV
Drop your MP4 above — or several at once — keep the format on WAV and pressConvert to WAV. The sound is taken out of the video and saved as a WAV file, ready to open in an audio editor or send to a transcription service.
When WAV is the right choice
WAV stores sound without compression. That makes it large, but it is the format audio editors such as Audacity, GarageBand and Premiere, many transcription and captioning services, DJ software and samplers expect — and you can edit and save it as many times as you like without the quality dropping.
How big the files are
| Length | WAV | MP3 at 192 kbps |
|---|---|---|
| 1 minute | about 10 MB | about 1.4 MB |
| 10 minutes | about 100 MB | about 14 MB |
| 1 hour | about 600 MB | about 85 MB |
If you only want to listen to the audio or share it, choose MP3 instead — or use theMP4 to MP3 converter. To keep the sound exactly as it is in the video at a fraction of WAV's size, use Extract Audio from Video.
Only part of the sound
Trim the video first with Cut & Merge, or cut it into pieces with Split Video, then convert just the part you need.
Frequently asked questions
How do I convert MP4 to WAV?
Drop the MP4 above, leave the format on WAV and press Convert to WAV. The sound is taken out of the video and saved as a WAV file. You can convert several videos at once.
Why would I want WAV instead of MP3?
WAV is uncompressed, so it is what many audio editors, transcription services, DJ software and samplers ask for. It is also a good format to keep while you edit, since saving it again does not lower the quality. For listening or sharing, MP3 is far smaller.
How big is a WAV file?
About 10 MB per minute of stereo sound — roughly seven times the size of a 192 kbps MP3. A one-hour recording is around 600 MB.
Does WAV improve the sound?
No. WAV keeps the sound exactly as it is in the video, without any further loss, but it cannot add detail that was not there. It is the right choice when the next step is editing, not for making a clip sound better.
Can I convert other videos to WAV?
Yes. MOV, MKV, WebM, AVI and anything else your browser can play work the same way as MP4.
Is my video uploaded?
No. The conversion runs in your browser, so your video never leaves your device.
