Convert MP4 to WAV
100% private — runs on your device, never uploaded. Works offline once loaded.
WAV is what audio software asks for. Editing suites, speech-recognition tools, forced-alignment scripts and game engines all prefer uncompressed audio, because every sample is already there with nothing to decode and no codec support to worry about. Extracting WAV from an MP4 gives them exactly that — but it does not improve anything: the audio in the video was already compressed, and storing it uncompressed simply stops any further loss from here on. Expect roughly 10 MB per minute in stereo, which is the trade you accept for a format that every piece of audio software opens without complaint.
Frequently asked questions
Will WAV sound better than the MP4 audio?
No. It contains exactly what the video contained, stored uncompressed. It prevents further loss rather than recovering any.
Why is the file so large?
Nothing is compressed — roughly 10 MB a minute in stereo. That is the cost of the format editing software wants.
Is my video uploaded?
No — the extraction runs in your browser.
