What is MP4?

MP4 is the most compatible video format: it plays on every phone, browser, TV and social network. It usually holds H.264 or H.265 video and AAC audio.

What is WAV?

WAV is uncompressed audio, the format of recording studios and Windows. Quality is perfect, but a minute of stereo takes about 10 MB.

Questions

Does converting MP4 to WAV lose quality?
No. WAV is lossless audio, so the sound is kept exactly. Converting from a compressed format like MP3 won’t bring back what it removed, though.
Do you store my files?
No. Your files are never uploaded, so there is nothing for us to store. They only exist in your browser’s memory while the page is open and are deleted when you remove them, clear the list or close the tab. We only count anonymous usage, like how many conversions happen, never file names or contents.
Is it safe?
Yes. Your files are converted on your own device and are never uploaded to any server.
Is it free?
Yes. It’s free, with no sign-up, no watermarks and no ads.
Is there a limit?
We don’t set any limit on the number or size of files. Since everything happens on your device, its memory is the real limit: on a computer, 100-megapixel photos, 300-page PDFs and long videos convert without trouble. Phones have less room. Video and audio use your browser’s codecs, so Chrome and Edge support the most formats. If something doesn’t work, we’ll tell you.
Does it work on my phone?
Yes, in any modern browser on iPhone, Android or desktop.
