Questions
How do I convert a WAV file to MP3 for free?
Pick the WAV file on this page and press Convert to MP3. The conversion runs in your browser, with no charge and no account.
Why is my WAV file so big?
WAV stores sound without compression, so each second of audio takes a lot of data. CD-quality sound uses 1,411 kbps. MP3 packs the same sound into far fewer bits.
How much smaller will the MP3 be?
At 192 kbps the MP3 is about 14 percent of the size of CD-quality WAV, which is roughly one seventh. A lower bitrate makes the file smaller still.
Why does this converter accept WAV in any browser?
WAV needs no decoder, so every current browser can read it. That is why WAV files open the same way on most phones and computers.
