How it works
- Drop your WAV onto the box above: 16-bit, 24-bit or 32-bit float, any sample rate.
- Pick 192 kbps, or 320 for music and 128 for speech.
- Download the MP3. It's made on your device; the WAV never leaves it.
- Sound noisy or too quiet? One click sends the same file to the noise remover or the loudness normalizer.
How much smaller
- A minute of CD-quality stereo WAV (44.1 kHz, 16-bit) is about 10.6 MB.
- As MP3 at 320 kbps it's 2.4 MB; at 192, 1.4 MB; at 128, under 1 MB.
- A mono WAV stays mono, and stereo stays stereo.
WAVs from recorders, DAWs and Audacity
Field recorders, DAWs and Audacity save WAV because it's uncompressed and safe to edit. For sharing, uploading or a podcast host, MP3 is the format everything takes.
24-bit and 32-bit float WAVs are read at full precision before encoding. MP3 goes up to 48 kHz, so 88.2 and 96 kHz recordings are resampled to 48 kHz. Files with more than two channels are mixed down to stereo.
The MP3 starts exactly where the WAV does: the encoder's own lead-in is taken into account, so it lines up to the sample if you put it back on a timeline.
Questions
Is my file uploaded anywhere?
No. The conversion runs inside your browser, on your own device. Your file never leaves it, so there's no upload to wait for and nothing stored on a server.
Is it really free?
Yes. Converting is free with no limit, no account and no watermark. AudioRinse earns from its cleaning tools; the converters are here because a recording often needs both.
Which bitrate should I pick?
192 kbps sounds like the WAV for speech and most music, and it's the default. 320 kbps is the highest MP3 quality, for music and mixes you'll share. 128 kbps is plenty for speech: lectures, podcasts, voice notes.
Should I keep the WAV?
Yes, if you might edit again. MP3 drops detail you can't hear in order to be small, and editing an MP3 and saving it again loses a little more each time. The WAV is your master.
How long can the file be?
Up to 4 hours. It converts many times faster than it plays: an hour of audio takes a few minutes.
The sound is noisy or too quiet. Can I fix it?
Yes. After converting, one click sends the same file to the background noise remover, the loudness normalizer or the buzz and hum remover. Cleaning is free to try; the free plan includes 3 downloads a month.
