Questions

How do I convert MP4 to WAV?

Open the converter, pick the MP4, trim it if you like, then tap Extract audio. WAV is already chosen on the download button, so the next tap saves it.

Does my MP4 get uploaded?

No. The conversion runs in your browser, so the video never leaves your device, and a big file doesn't wait on an upload.

Is there a size limit?

Videos can be up to 500MB and 20 minutes long. Trim first if you only need part of it.

Why are WAV files so big?

WAV keeps the audio uncompressed, which makes it the safest format to edit in a music or video app. For listening, MP3 is a fraction of the size and sounds the same to most ears.

Does it work on iPhone and Android?

Yes, in a recent version of Safari or Chrome, with nothing to install. Pick the video from your Photos or Files.

Is it free?

Yes. No sign-up, no watermark, and no limit on how many videos you convert to WAV.
