Why convert MP3 to WAV?
Audio editors, DJ software, some hardware samplers and transcription services want WAV. MP3 to WAV gives them an uncompressed file.
- MP3: lossy: some detail is removed.
- WAV: no quality loss.
- WAV: accepted by every audio editor.
Converting to WAV cannot restore detail MP3 already removed; it only avoids further loss when you edit and re-export.

Does converting MP3 to WAV lose quality?
WAV is uncompressed, so nothing further is lost. It cannot restore detail the MP3 already lacks, though, so the file gets bigger without sounding better.
How long does it take?
A few seconds for a song, and under a minute for an hour-long recording on most computers.
What is an MP3 file?
MP3 is the most widely used audio format in the world. It removes sounds people are unlikely to hear, shrinking a song to about a tenth of its CD size. At 192 kbps or higher most listeners cannot tell it from the original, and every device plays it. Its patents expired in 2017, so it is now free to use.
What is a WAV file?
WAV usually stores raw, uncompressed PCM audio, the same data as an audio CD. Quality is perfect but files are large: about 10 MB per minute of CD-quality stereo.
Frequently asked questions
Is the MP3 to WAV converter free?
Yes, completely free, with no sign-up and no watermark. Files up to 1 GB each can be converted, and there is no daily limit.
Do you keep a copy of my files?
We never receive them. All processing happens on your device, so there is nothing for us to store or delete.
Will the WAV sound as good as the MP3?
WAV is uncompressed, so nothing further is lost. It cannot restore detail the MP3 already lacks, though, so the file gets bigger without sounding better.
Can I convert WAV back to MP3?
Yes, use the WAV to MP3 converter.
An MP3 sounds thin or has artefacts. What should I do?
It was probably encoded at a low bitrate. Re-encoding cannot restore it; find a better source.
Can I use it on my phone?
Yes. Open the page in your phone's browser and choose a file. Phones have less memory than computers, so very large files are better converted on a laptop or desktop.
