Frequently asked
Is the WAV audio lossless? +
Yes. WAV stores uncompressed PCM, so you get a faithful copy of the soundtrack decoded from your MP4. Good for editing or archiving.
Does it work in every browser? +
WAV is plain PCM and needs no extra encoder, so this tool runs in every modern browser. No downloads, and it starts converting right away.
Is my file uploaded? +
No. The audio is extracted locally in your browser, so the MP4 stays on your device. Want a smaller compressed file? Try the MP4 to MP3 tool instead.
