# Convert MP4 to WAV.

> Pull the audio out of video as WAV — ready for any editor.

Editors, transcription suites and samplers want WAV, not video. Drop an MP4 or MOV and the audio track comes out as standard 16-bit PCM WAV — **decoded entirely in your browser, with no upload and no length limit**.

**No uploads · No ads · Free & open source.**

## How it works

1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V.
2. Pick a quality or preset — or set an exact target size and let the tool find it.
3. Compress, compare before/after, and download — individually or as a ZIP.

## Straight into the editing chain

Extracting WAV is the cleanest handoff into an edit: one decode, zero re-encodes, and every DAW and transcription tool accepts the result. When the deliverable is the recording itself, [MP4 to MP3](https://compress-pro.com/mp4-to-mp3) makes the small copy instead — and the [audio tool](https://compress-pro.com/compress-audio) offers M4A, OGG, FLAC and target-size mode for everything in between.

## Frequently asked questions

### Why WAV instead of MP3?

WAV skips a lossy re-encode — the video’s audio is decoded straight to raw samples, so nothing is lost on the way into your editor. If small and shareable is the goal instead, extract to MP3.

### How big will the WAV be?

About 10 MB per stereo minute regardless of the video’s size — the picture is discarded and the sound is unpacked to raw PCM. An hour of footage yields roughly 600 MB of WAV.

### Which video formats work?

MP4, M4V and MOV — phone footage, screen recordings, camera clips. Drop several at once and each video produces its own WAV, downloadable individually or as one ZIP.

### Is it private?

Yes. The audio is decoded and re-encoded entirely in your browser — recordings never leave your device, and the server does nothing but deliver this page. Voice memos, interviews, demos: none of it is uploaded anywhere. Want proof? Run one file through, switch your connection off, and run another — it still works.
