Convert MP3 to WAV
Updated Jul 2026
MP3 is the compressed format almost everything plays, and WAV is the uncompressed format editing software and some hardware expect. To convert MP3 to WAV, open the file in a converter and export it as WAV. Doing it on your own computer means the audio file never has to leave your machine to make the trip.

How to convert MP3 to WAV
- Open Morphjet and drag in the MP3 file you want to convert. You can add a single track or a whole folder of them.
- Choose WAV as the output format.
- Convert. The WAV file is written next to your original, and nothing leaves your machine.
MP3 vs WAV: what actually changes
| MP3 | WAV | |
|---|---|---|
| File size | Small, compressed | Large, roughly 10 times bigger |
| Quality | Lossy, some detail discarded when encoded | Lossless, but converting from MP3 can't restore what MP3 already threw away |
| Compatibility | Plays on nearly everything | Widely supported, standard in editing and production software |
| Metadata (tags) | Yes, artist, album, and art via ID3 tags | Limited, tag support is inconsistent between programs |
| Good for editing | Not ideal, re-encoding loses more quality | Yes, the standard format for recording and editing |
When to convert, and when not to
Convert MP3 to WAV when an editing program, sampler, or piece of studio hardware needs an uncompressed file, or when a workflow specifically calls for WAV.
Keep the MP3 if you're just listening or sharing music casually, because converting to WAV doesn't bring back any quality the MP3 already lost, and you'll end up with a much bigger file for no real gain.
Why not just use an online converter?
Some online converters ask you to upload your audio to their server, convert it, then let you download it back, which means a copy of your file sits somewhere you don't control. Converting on your own computer skips that entirely. The MP3 goes in, the WAV comes out, and neither one ever crosses the internet.
Questions
Does converting MP3 to WAV improve the sound quality?
No. WAV is uncompressed, but converting an MP3 to WAV just unpacks the audio that's already there. Whatever detail the MP3 encoding discarded is gone for good, and a WAV made from an MP3 sounds the same as the MP3, just bigger.
Why would I want a WAV instead of just keeping the MP3?
Some editing software, samplers, and older audio hardware expect uncompressed WAV files and either can't read MP3 or handle it poorly. If a program or device asks for WAV, that's the real reason to convert.
Will the WAV keep the song's artist and album info?
Not reliably. MP3 stores that information in ID3 tags, but WAV's tagging support is inconsistent across different programs, so titles, artist names, and cover art may not carry over.
Can I convert MP3 to WAV without uploading the file anywhere?
Yes. A desktop app like Morphjet converts the file on your own computer, so it never has to be sent anywhere to come back as a WAV. You can do it with your wifi off.
Morphjet converts MP3, WAV, and 1,800+ other formats, all on your machine. Launching this July.
