MP4 to WAV Converter
Extract the audio from an MP4 video as an uncompressed WAV file — in your browser.
MP4 stores compressed audio, but for editing, mastering, or transcription you often want WAV — an uncompressed, lossless format that audio software handles cleanly.
This tool extracts the audio track from your MP4 and writes it to WAV locally. Nothing is uploaded.
