Is Video to WAV free? Is there a watermark?

Yes — Video to WAV is free to use with no sign-up or watermark. Very large files can still be limited by your browser's available memory and processing resources.

Do my files get uploaded to a server?

No. Video to WAV runs entirely in your browser with WebAssembly, so your MP4, MOV, WebM, MKV file never leaves your device and nothing is stored or seen by us.

What can I put in, and what do I get out?

Video to WAV accepts MP4, MOV, WebM, MKV and gives you back a WAV file. Actual codec support depends on what the bundled engine or browser decoder can read.

What quality is the WAV audio?

The result is uncompressed 16-bit stereo PCM. It can be much larger, and decoding compressed source audio into WAV does not restore lost detail.

Get a better result

Best for: Editing, transcription, analysis, and follow-on processing that expects straightforward uncompressed PCM rather than a compact listening file.
Input → output: The default video audio stream is decoded into an uncompressed 16-bit stereo WAV file. Video frames are not included in the result.
Quality tip: Use WAV when editability matters more than storage. Confirm that forced 16-bit stereo suits the receiving editor or transcription service.
Know before running: The output can be much larger, mono or multichannel inputs are converted to stereo, and decoding compressed audio into PCM cannot restore detail previously discarded.
Next step: Audio to MP3 to create a broadly supported distribution copy after editing or transcription.
