What happens when you convert MP3 to WAV
| Compression | Lossy → Lossless |
|---|---|
| Size per minute | MP3 ≈ 1.4 MB → WAV ≈ 10.6 MB |
| Quality | No further loss, but the WAV cannot restore what MP3 compression removed |
| Tags | Title, artist and album tags are copied when the target format supports them |
| Opens in | every computer and audio editor; too large for most messaging apps |
Sizes are typical values; your files will vary with content and settings.
MP3 MPEG-1 Audio Layer III
MP3 is the most compatible audio format in existence. Every phone, car stereo, browser and editor plays it, and 128 to 320 kbps gives small files that sound good for music and speech.

Why convert MP3 to WAV?
MP3 is the format of most music downloads, podcasts and audio libraries. It is lossy, so re-encoding repeatedly reduces quality. Choose WAV to edit the audio or upload it to a service that requires uncompressed audio.
Frequently asked questions
Will the WAV lose quality?
WAV is lossless, so the conversion keeps every pixel or sample that is in your MP3 file. It cannot bring back detail that MP3 compression already removed, and the WAV file will usually be larger.
Will the WAV be smaller than the MP3?
No, usually larger: a minute of audio takes about 1.4 MB as MP3 and about 10.6 MB as WAV. WAV is lossless, so its size depends on the audio rather than a bitrate setting.
