Some editing, transcription or music software, and some devices, ask for WAV. Converting an MP3 to WAV gives that uncompressed file, readable by all these tools. The quality stays that of the MP3: the WAV adds nothing, it only avoids losing more.
How to convert MP3 to WAV
- 1Drop your MP3 files in the box, or click to pick them. You can add several at once.
- 2WAV is already selected. Open the settings if you want to change the quality, the size or the background.
- 3Download each file, or everything at once as a .zip. Nothing was uploaded: the conversion happened on your device.
The formats
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.
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.
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
Does WAV sound better than MP3?
No, it sounds exactly the same. What was lost when encoding the MP3 does not come back.
Why is the file so heavy?
WAV is not compressed: about ten megabytes per minute at CD quality, ten times more than MP3.
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.
