    About the MP4 format

    MP4 is the universal video container: phones record it, every site streams it and every device plays it. Its soundtrack is usually AAC audio. When only the sound matters, a lecture, a concert recording or a podcast published as video, extracting it to an audio file saves most of the space.

    About the WAV format

    WAV (Waveform Audio) stores audio uncompressed as raw PCM samples, exactly as it was recorded or decoded. It is the standard for recording, editing and mastering because nothing is lost, and it plays everywhere. The price is size: a minute of CD-quality stereo takes about 10 MB.

    Frequently asked questions

    Why convert MP4 to WAV?

    WAV keeps every sample exactly, which makes it the safe choice for editing, mastering and archiving. An MP4 video is many times larger than its soundtrack and cannot be played in audio-only apps.

    Does converting MP4 to WAV lose quality?

    No. WAV is a lossless format, so every sample of the decoded MP4 audio is stored exactly. The file is usually larger than the original.

    What happens to the video?

    Only the soundtrack is kept. The MP4 file's picture is dropped and you get a plain WAV audio file, which is exactly what you want for music, lectures or podcasts recorded as video.

    Can I convert several MP4 files at once?

    Yes. Add up to 5 files of up to 200 MB each, convert them in one go and download the results one by one or as a ZIP.

    Are my files uploaded?

    No. The conversion runs in your browser with ffmpeg compiled to WebAssembly. Your MP4 files never leave your device.

    Is this MP4 to WAV converter free?

    Yes, completely, with no sign-up and no watermark. The site is supported by ads.
