How to convert MP3 to WAV
Upload your MP3 file
Drag and drop a MP3 file to turn into WAV, or click to browse. Anything under 1GB, and nothing is installed.
Confirm WAV as the output
WAV is already selected for your MP3. Switch between MP3 and WAV if you change your mind.
Convert and download
We convert the MP3 on our servers, usually in under a minute. Create a free account to download the WAV.
Why convert MP3 to WAV?
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 to WAV questions
Is the MP3 to WAV converter free?
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.
Do I need to install any software?
No. The conversion runs on our servers and you use it from a browser tab, so it works the same on Windows, macOS, Linux, iPhone and Android. Nothing to install at either end. Where MP3 plays: Every device made in the last 25 years. Where the WAV you get back plays: Every desktop and audio tool; large for phones.
Does converting MP3 to WAV reduce the quality?
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.
How large a file can I convert?
Anything under 1GB per upload, which is more footage in some formats than others. MP3: Roughly a tenth of uncompressed audio. WAV coming back: About 10 MB per minute in stereo. For anything bigger, trim or compress it first, both are free tools here.
Is my file kept private?
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.
Does converting MP3 to WAV improve the quality?
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.
