Convert WAV to MP3 free by dropping your files anywhere on this page. LAME encodes each one at 320 kbps by default and saves it as an MP3. Batch as many as you want; your audio is never uploaded or stored.
Which bitrate?
The default is 320 kbps, the highest MP3 allows, so you never have to wonder whether you gave up quality. 192 is transparent for nearly all music if you want smaller files, and 128 is plenty for speech and voice memos. Every option is far smaller than the WAV: a 50 MB WAV comes back around 11 MB even at 320.
FAQ
Any file limits?
None. Batch a whole folder of session exports. Big files work best on a computer.
