About the MP4 to WAV Converter
This MP4 to WAV converter turns videos from MP4 into WAV without installing software or uploading anything. It solves a common problem: sometimes you only need the audio track, a GIF or still frames from the video. Converting to WAV gives you uncompressed WAV for editing, ideal for audio editing, studio work, broadcast, transcription tools and sound effects.
Audio and video are processed by FFmpeg compiled to WebAssembly, the same open-source engine behind VLC and HandBrake, running inside your browser tab. Because everything happens on your own device, your videos are never uploaded, stored or seen by anyone else, which makes it safe for family videos, client footage and private recordings.
What to expect: only the soundtrack is kept and encoded as WAV; the processing engine (about 30 MB) is downloaded once and then cached by your browser.
How to use the MP4 to WAV Converter
- Click "Choose files" or drag your MP4 videos onto the box. You can add several at once.
- Choose mono or stereo; WAV is saved as uncompressed 16-bit PCM.
- Press "Convert to WAV". The conversion runs on your device and shows its progress.
- Download each WAV file, or use "Download all (ZIP)" when you converted several.
- Open the result in Audacity or Adobe Audition to check it; your original MP4 is never changed.
Tips & benchmarks
- WAV is uncompressed 16-bit PCM, so it is large but loses nothing further and edits cleanly.
- Very large videos (over about 1 GB) may exceed the memory of a phone browser; trim them first with our Trim Video tool.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the WAV to a website or government portal.
