The same minute of sound, in each version. Bitrate sets the file size of an MP3; the sample rate and bit depth set the size of a WAV.

Version	Size of one minute
WAV, 16-bit, 44.1 kHz	About 10.6 MB. Uncompressed: this is the source.
WAV, 24-bit, 48 kHz	About 17 MB. Common in studios and on field recorders.
MP3 at High	WAV to MP3 320 kbps: about 2.4 MB, roughly a quarter of the WAV.
MP3 at Standard	192 kbps: about 1.4 MB, about one seventh of the WAV.
MP3 at Small file	128 kbps: about 1 MB, a tenth of the WAV.
Email attachment	Many email services stop attachments at 25 MB. That is about 2 minutes of WAV, or about 17 minutes of MP3 at 192 kbps.

Which bitrate
Standard, 192 kbps, suits most music and all speech. Pick High, 320 kbps, for music you want to keep. Small file is enough for voice notes.
Quality loss
MP3 removes sound most people do not hear, and the quality loss is small at 192 kbps and above. Keep the WAV if you may edit the track again.
Send by email or chat
A WAV is often too big to send by email or chat. As an MP3 it fits most limits, and every phone plays it.
With VLC or Audacity
For WAV to MP3 VLC uses Media, Convert and Save, with the Audio - MP3 profile. For WAV to MP3 Audacity uses File, Export Audio, then MP3.

How much smaller is an MP3 than a WAV?: About seven times smaller at 192 kbps, and about four times at 320 kbps. Each file's row shows the WAV size first and the MP3 size after.
How do I convert WAV to MP3 on Mac?: In Safari or Chrome, drop the files. For WAV to MP3 Mac users can also use the Music app with the MP3 Encoder import setting.
Can I convert many WAV files at once?: Yes. Drop a whole folder. The batch gets one bitrate, and Download all saves every MP3.

Big WAV files take long to upload, and upload sites keep them for a while. Your browser turns each WAV file to MP3, so nothing leaves your device.
