Your MP3 will be a fraction of the WAV's size.
The same sound in a file up to 10 times smaller
Voice recorders, editing programs and many USB microphones save in WAV, an uncompressed format that takes about 10 MB per minute. To send that recording by WhatsApp, upload it to a platform or keep it on your phone, MP3 is far more practical.
At 320 kbps, the format's maximum quality, an MP3 sounds practically the same as the original WAV on any home equipment and is about a quarter of the size.
Which quality should I choose?
256 kbps
Almost indistinguishable from 320 and a bit lighter.
192 kbps
Very good quality with a noticeably smaller file.
128 kbps
For voice, classes or podcasts, or when space really matters.

Frequently asked questions about WAV to MP3
Is quality lost?
MP3 is a compressed format, so technically yes, but at 320 kbps the difference isn't noticeable on regular equipment. If you need zero loss and a smaller size, use FLAC in Convert audio.
Can I do the opposite?
Yes, with MP3 to WAV.
Does it cost anything?
