How to convert MP3 to WAV
- Choose or drop your MP3 files. You can add several at once.
- Check that “To” is set to WAV.
- Press “Convert to WAV” and download the results — or all of them as one ZIP.
MP3 vs WAV
MP3 — MPEG-1 Audio Layer III. MP3 is the universal compressed audio format. At 192 kbps it sounds close to the original for most listeners at about a tenth of the size of WAV.
WAV — Waveform Audio File. WAV stores uncompressed audio, exactly sample for sample. Files are large (about 10 MB per stereo minute) but lose nothing, which is why audio editors and DAWs prefer it.
Convert MP3 to WAV when you need a file for editing, mastering and importing into audio software. MP3 is better suited to music libraries, podcasts and playing on any device.
FAQ
5Are my files uploaded anywhere?
No. The conversion runs in your browser using your own device’s processor. Your files are never sent to a server, so nobody — including us — can see them. You can even disconnect from the internet after the page loads.
Will I lose quality?
WAV is uncompressed, so nothing is lost in this step, though WAV cannot restore detail that MP3 compression already removed. Expect a much larger file.
Is there a file size or daily limit?
No limits, and no sign-up. Because nothing is uploaded, we don’t pay for your conversions and have no reason to cap them. Very large files are limited only by your device’s memory.
Can I convert many MP3 files at once?
Yes. Add as many files as you like; each is converted to WAV, and “Download all” saves them together as a ZIP.
Does it work on iPhone and Android?
Yes. It works in any modern browser — Safari, Chrome, Firefox or Edge — on phones, tablets and computers. Older or low-memory phones may be slower with very large files.
