WAV to MP3: common questions
Does converting WAV to MP3 lose quality?
A minute of stereo WAV takes about 10 MB; as MP3 at 192 kbps, about 1.4 MB. Keep the WAV if you are still editing.
How many files can I convert at once?

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?

Is it really free?
