How this tool works

Every tool on Quikbench follows the same rule: your files are read, converted, and turned into a download entirely inside this browser tab — nothing is ever uploaded to a server.

MP4 to WAV Converter

Extracts the audio track from an MP4 file and re-encodes it as standard 16-bit PCM WAV entirely locally in your browser — nothing is sent to a server, and the video itself is never touched or re-encoded.

Convert one file at a time, or queue several MP4 files and convert them all to WAV in a single batch, with a zip download when you're done.

Local encoding, real results

Every WAV file this tool produces is a real, standard PCM WAV — ready to drop straight into a video editor, DAW, or transcription tool.

Why extract WAV audio from MP4?

WAV is the format most editing and transcription tools expect for clean, lossless audio work — pulling a WAV track out of an MP4 is the standard first step before editing dialogue, cleaning up podcast audio, or feeding a recording into transcription software. Note that some MP4 files use codec combinations your browser can’t decode; if a file fails, try re-exporting it with standard H.264/AAC encoding first.

What this tool doesn't do

This is a straightforward format conversion — it doesn't trim, normalize volume, or edit the audio in any way. If you need to cut a clip or adjust levels, do that in a dedicated audio editor before converting here. Need other formats too? The full Audio Converter handles MP3, WAV, M4A, MP4, AAC, OGG, and FLAC in one place.

Frequently asked questions

Drop your MP4 file into the box above, wait a moment while it's read in your browser, then hit Convert and download the WAV file. No account or install needed.

Just the audio. This tool reads the audio track out of your MP4 file and converts that — it doesn't touch or re-encode the video, and no video is produced as output.

No. The whole conversion, from reading the MP4 file to producing the WAV download, happens locally in your browser tab using the Web Audio API. Nothing is sent to a server.

Yes, there's no cost, no account, and no watermark. Since conversion happens on your device, there are no server-side usage limits either.

It depends on the direction. Converting a lossy format (like MP3, MP4/AAC audio) to WAV doesn't recover any quality that was already lost — it just repackages the same audio uncompressed. Converting to MP3 applies lossy compression, so some quality is deliberately traded for a smaller file.

Yes — queue up to 20 files (300MB combined) and convert them all in a single batch, then download everything as one zip file.

Any modern browser with Web Audio API support — Chrome, Edge, Firefox, and Safari all work. If a specific file fails to decode, try a different browser, since audio/video codec support varies slightly between them.
