The WAV to MP3 Converter runs wav to mp3 in your browser, turning large uncompressed recordings into MP3 files you can actually send. Drop the WAV and download the MP3. The recording never leaves your device: nothing is uploaded or stored, and it spends no credits.
Why are WAV files so big?
WAV stores audio uncompressed: every sample, as recorded. That is exactly why field recorders, audio interfaces and DAWs such as Logic, Ableton or Reaper work in it. Nothing is thrown away while you record and edit. The cost is size. A long interview, a band rehearsal or a full album bounce in WAV can be far too heavy for an email attachment, a messaging app or a quick upload.
MP3 compresses the audio by leaving out what most listeners won’t notice. The result is a fraction of the size and plays on phones, car stereos, smart speakers and podcast hosts.
How do I convert WAV to MP3?
- Drop the WAV file, or pick it from your device.
- MP3 is selected. Choose 128, 192 or 320 kbps.
- Convert, follow the progress bar, and download.
Encoding uses LAME, the MP3 encoder, inside your browser. Stop cancels the job at any point. One file converts at a time. A very long WAV is held in memory while it converts, so the largest files depend on how much your device has.
Which bitrate is right for a WAV?
Since a WAV has no compression to begin with, this is the one case where the bitrate choice decides almost everything about how the MP3 sounds.
- 320 kbps for finished music: a mix to send to bandmates, a demo for a client, a master preview.
- 192 kbps for most uses, including podcasts with music beds.
- 128 kbps for speech only: interviews, voice-overs, dictation and lectures.
Keep the original WAV if you will edit again later. Every MP3 is a lossy copy, and you want to go back to the source for the next round. Have Apple audio instead? M4A to MP3 handles Voice Memos and iTunes files.
FAQ
Is my recording uploaded?
No. The wav to mp3 conversion runs in your browser, and nothing is stored.
Does WAV to MP3 lose quality?
Yes, some, since MP3 is a compressed format. 320 kbps keeps as much as MP3 allows; 128 kbps suits speech.
What does it cost?
It comes with the Nexin library: Nexin Lite or Nexin Pro opens it, and it spends no credits.
