WAV to MP3 Converter

WAV files are large because they store sound without compression, which makes them awkward to email, upload or keep on a phone. Drop your WAV files here and they are saved as MP3, which plays on every device and takes a fraction of the space. Choose 320 kbps for the best quality, 192 kbps for music at a smaller size, or 128 kbps for speech. Convert a whole batch, listen to each MP3, and download them together in a ZIP. Your recordings stay on your device.

How it works

WAV to MP3 Converter is a web page that does its work on your own device. The file you choose is opened by your browser, changed there and saved from there; it is never sent to a server, so there is no copy of it anywhere to delete, no queue and no waiting for an upload. Most online tools of this kind send your file to their servers and work on it there, and many keep it for a while. This one does not. There is no account, no watermark and no limit on how often you use it, and the result downloads the moment it is ready.

How much smaller the MP3 will be

CD-quality stereo WAV uses about 10.6 MB for every minute. The same minute takes about 2.4 MB as a 320 kbps MP3, 1.4 MB at 192 kbps and 1 MB at 128 kbps, so a 50 MB song becomes roughly 5 to 11 MB.

Keep the WAV for editing

MP3 is for listening and sharing. If you still plan to edit or master the recording, keep the WAV as your working copy and make an MP3 from it at the end.

Questions

What bitrate should I use to convert WAV to MP3?

Use 320 kbps if the recording is music you care about, 192 kbps for everyday listening, and 128 kbps for voice recordings, lectures and podcasts, where it sounds clear at the smallest size.

Does WAV to MP3 lose quality?

MP3 leaves out sound detail that is hard to hear in order to make the file smaller. At 320 kbps the difference is very hard to hear; at 128 kbps music can lose some sparkle. Keep the WAV if you may need the full quality later.

Is the sample rate kept?

Yes, for 44.1 and 48 kHz WAV files. MP3 goes up to 48 kHz, so higher-rate studio files are saved at 48 or 44.1 kHz.

Can I convert 24-bit WAV files?

Yes. Current browsers open 24-bit and 32-bit float WAV recordings, and they convert like any other WAV.

Are my WAV files uploaded?

No. The conversion runs inside your browser, so your recordings are never sent anywhere.
