Turn your MP3 file into a WAV that plays where you need it, right in your browser.
Drag and drop the file, or click to browse. Files up to 500 MB are supported, and nothing is installed.
WAV is already selected. Switch between MP3 and WAV if you change your mind.
We convert on our servers, usually in under a minute. Create a free account to download the WAV, or keep editing the file in REQO.
MP3 is the universal audio format. It is lossy, so it throws away detail you are unlikely to hear, and in exchange the file is small enough to email and playable on absolutely anything.
The practical problem: Lossy, so it is not the right master format for further audio editing. No support for multiple tracks or lossless quality.
WAV solves that. Lossless, so repeated edits and exports never compound compression artefacts. The format audio editors, DAWs and mastering tools expect.
Worth being clear about this one: converting MP3 to WAV cannot restore detail the MP3 encoder already discarded. What it does give you is an uncompressed file that editors and DAWs accept and that will not lose more quality with each subsequent export.
| MP3 | WAV | |
|---|---|---|
| Container | MPEG audio layer III | RIFF / WAVE |
| Typical codecs | MP3 (lossy) | Uncompressed PCM |
| Best for | Podcasts, voice notes, music you need to send | Editing, mastering, voiceover work |
| Plays on | Every device made in the last 25 years | Every desktop and audio tool; large for phones |
| File size | Roughly a tenth of uncompressed audio | About 10 MB per minute in stereo |
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the WAV itself beyond the free-plan badge.
No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android.
Converting to WAV adds no further loss, but it cannot restore anything the MP3 encoder already discarded. You get a clean, uncompressed working file, not a better-sounding one.
Up to 500 MB per file. For anything bigger, trim or compress it first, both are free tools here.
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
No. The data the MP3 encoder threw away is gone for good. What you gain is a lossless working file, so further edits and exports stop compounding compression artefacts.
