About the MP4 to WAV converter
Extract video audio as an uncompressed WAV file — the format of choice when you plan to edit the audio afterwards, since WAV loses no quality.
Everything is processed in your browser with no upload. Expect larger files than MP3: that is the nature of uncompressed audio.
Frequently asked questions
Why choose WAV over MP3?expand_more
WAV is uncompressed, so nothing is lost — ideal for editing, mixing, or transcription. Choose MP3 when you just want small files for listening.
Why is the WAV file so large?expand_more
Uncompressed audio stores every sample as-is. A few minutes of audio can be tens of megabytes — that is normal.
Does the conversion happen locally?expand_more
Yes — the video is decoded and the WAV is written entirely on your device.
