How do I check the MP3 before I save it?
To convert WAV to MP3 for free, choose the WAV above, keep MP3 selected, and select Convert to MP3. Your browser encodes a 192 kbps MP3 in seconds, with no upload. Play it on this page before you download it.
Play it here first
A player appears under the download button. Compare a quiet passage and a loud one with the WAV in your head.
Expect the same sound, in a smaller file
At 192 kbps most people cannot tell the MP3 from the WAV on speech or a finished mix.
Why convert WAV to MP3?
A WAV is uncompressed, which is right for editing and wrong for sharing. Converting WAV to MP3 makes a file that sends, uploads, and plays anywhere.
The file is too big to send
Ten minutes of stereo WAV is about 100 MB. As a 192 kbps MP3 it is about 14 MB, small enough for email or chat.
An upload form wants MP3
Podcast hosts, contest entries, and course platforms often ask for MP3 or cap the file size.
A phone or car that skips WAV
Some players and car stereos read MP3 only. Convert the WAV and it plays.
Noise in the recording
Clean the WAV first, while it is lossless, then convert the result to MP3.
Remove background noise from audioHow much smaller is an MP3 than a WAV?
A CD-quality stereo WAV uses 1,411 kbps. The MP3 this page writes uses 192 kbps, a little over one seventh.

|---|---|---|
| 1 minute | About 10 MB | About 1.4 MB |

192 kbps, with the same channels as the WAV. That is about 1.4 MB per minute of stereo audio.
