How to convert MP4 to WAV

  1. Add your MP4 files. Drag them onto the box above or click to choose them. You can add several at once.
  2. Check the target is WAV. It is already selected. Adjust the quality under Options if you want.
  3. Click Convert. The conversion runs in your browser — the file is never uploaded to a server.
  4. Download the WAV. When it finishes, click Download on each file.

When you need this

Cleaning up dialogue in Audition or Audacity, syncing sound in Premiere or DaVinci Resolve, or sampling a clip.

MP4 vs WAV

MP4

The universal video format. H.264 video with AAC audio in an MP4 plays on every phone, browser, TV and social network.

Best for: sharing, uploading to YouTube, Instagram or TikTok, and playing anywhere.

WAV

Uncompressed PCM audio. Every sample is stored as-is, so there is nothing to decode and nothing lost — at the cost of roughly 10 MB per minute of stereo.

Best for: video editors, DAWs, samplers, broadcast and any tool that wants raw audio.

Will I lose quality?

Converting MP4 to WAV does not bring back what the MP4 compression already removed: the WAV will sound exactly like the MP4, only bigger. Do it when an app or device asks for WAV, not to improve the sound. The good news is that nothing more is lost either.

Have a link instead of a file?

Paste it into the YouTube to WAV converter and skip the conversion.

Frequently Asked Questions

How do I convert MP4 to WAV?
Drag the MP4 file onto the box above, check the target is WAV and click Convert. As soon as it finishes a Download button appears. Nothing to install, no account needed.
Is it free to convert MP4 to WAV?
Yes, completely: no sign-up, no daily limit and no watermark. Your own browser does the conversion, so it costs us nothing and there is no reason to charge for it.
Are my files uploaded to a server?
No. The converter runs inside your browser: the file is read and converted on your device and never leaves it. That is why it is safe for private or work recordings.
Will I lose quality?
Converting MP4 to WAV does not bring back what the MP4 compression already removed: the WAV will sound exactly like the MP4, only bigger. Do it when an app or device asks for WAV, not to improve the sound. The good news is that nothing more is lost either.
Is there a file size limit?
Up to 1 GB per file. The limit is not a business one but the browser’s: all the work happens in its memory, and above that size some browsers close the tab. On a phone, stay well below it.
Can I convert several files at once?
Yes. Add as many MP4 files as you like and they are converted one after another with a single click. Each one can go to a different format.
