A WAV weighs about ten megabytes per minute. Converting it to MP3 makes it five to ten times lighter, to send it, publish it as a podcast or play it on a phone, with no audible difference at 192 kbps.
How to convert WAV to MP3
- 1Drop your WAV files in the box, or click to pick them. You can add several at once.
- 2MP3 is already selected. Open the settings if you want to change the quality, the size or the background.

The formats
WAV
The uncompressed audio format of studios and editing software. It keeps full quality, but one minute of audio weighs about ten megabytes, ten times more than an MP3.
MP3
The universal audio format. It compresses with loss, almost inaudibly at 192 kbps, and plays on every device, player and app. It is the format to aim for when sharing audio.
Your files stay with you
The conversion runs in your browser, with your device's decoders. No file is uploaded, no copy is kept, and nobody but you sees your photos or videos. You can check it in the Network tab of your browser's developer tools: none of your files goes out.
Frequently asked questions
Is quality lost?
A little, but it is inaudible for most listening at 192 kbps and above. Keep the original WAV for studio work.
Can I convert a whole album at once?
Yes, drop all the files together, then download them as a .zip.
Is the converter really free?
Yes, with no sign-up, no watermark and no limit on the number of files. The conversion runs on your device and costs us nothing, so there is nothing to charge you for.
Are my files sent anywhere?
No. They are read and converted in your browser, then saved straight to your device. No server receives them.
Is there a maximum size?
The limit is your device's memory. Photos and audio files go through without trouble; for a video of several gigabytes, a computer does better than a phone.
Does it work on a phone?
Yes, on iPhone and Android, in Safari, Chrome or Firefox. For video, an up-to-date browser is needed: it provides the decoders being used.
