MP4 TO WAV

Convert MP4 to WAV

Extract a video's audio track and save it as a WAV. Drop in an MP4 and the sound is decoded and written out as a 16-bit WAV right in your browser. It is free, there is no sign-up, and your file is never uploaded.

Free, no sign-up. Converted in your browser — your file is never uploaded.

How it works

Three steps, all in your browser

01

Drop your MP4

Drag the video in or tap to pick it. The converter reads the audio track inside the MP4 — usually AAC — and ignores the video.

02

Convert in your browser

The decoded audio is written into a 16-bit WAV at the source sample rate. Nothing is uploaded to a server.

03

Download the WAV

A Download button hands you the WAV, ready to import into a DAW or video editor that prefers uncompressed audio.

Why convert MP4 to WAV

An uncompressed file your editor accepts

WAV is the format most DAWs and editors are happiest importing, so pulling a video's soundtrack into a WAV gives you a clean working file. Worth being honest, though: the audio inside an MP4 is normally AAC, which is lossy — so the WAV is lossless packaging of already-compressed audio, not a quality upgrade. Built for songs and clips up to 30 minutes or 500 MB.

Want a smaller, shareable file instead? Convert MP4 to MP3, or open the free audio converter to pick any output format.

FAQ

Frequently asked questions

How do I convert an MP4 to WAV?
Drop your MP4 onto the converter. The video's audio track is decoded and written out as a 16-bit WAV right in your browser, then a Download button appears. No install, no account, no upload.
Is the WAV truly lossless?
WAV is a lossless container, but the audio inside an MP4 is usually AAC, which is already lossy. So the WAV is a lossless package of already-compressed audio — it won't recover detail AAC discarded.
Is my file uploaded?
No — conversion happens entirely in your browser. Your file never leaves your device.
Does this keep the video?
No — you get just the audio as a WAV. The MP4 you dropped in is left untouched; the converter only reads its sound track.
How big a file can I convert?
The converter is built for songs and clips up to 30 minutes or 500 MB. WAV output is large, so long videos can hit that ceiling sooner than you expect.
