MP3 to WAV: common questions
Does converting MP3 to WAV lose quality?
The WAV is about 7 times larger and does not bring back the quality the MP3 lost, but editing it no longer makes it worse.
How many files can I convert at once?
Up to 10 audio files at once, up to 100 MB and 15 minutes each.
Does it work on a phone?
Yes, in current mobile browsers (Chrome, Safari, Edge, Firefox). Large files take a little longer on a phone, and the tab should stay open until the download is ready.
Are my files uploaded to a server?
No. The conversion happens inside your browser: the file is read and processed on your device and is not sent to Cocuyo or to any third party. You can check it in your browser’s network tools: your file is not sent.
Is it really free?
Yes. You can try it before signing up; to download the result we ask for a free account, with no subscription. Your free account comes with 30 welcome uses; after that, each use costs 1 credit (top-ups from US$1), and they are unlimited with Basic or Pro. It never adds a watermark.
