How to convert MP3 to WAV
- Click the box above or drag in your MP3 files.
- Keep "WAV" selected and choose the audio quality.
- Click "Convert" and download your WAV files.
Why convert MP3 to WAV?
MP3 is the universal audio format: every phone, car stereo, speaker, editor and website plays it. At 192 kbps it sounds great for music and speech while staying small.
WAV stores uncompressed audio. It is perfect quality and easy to edit, but files are about ten times larger than MP3.
Choosing the audio quality
- WAV is uncompressed, so the quality setting does not apply. Expect about 10 MB per minute of stereo audio.
Good to know
- Only convert recordings you own or have permission to use.
- Processing speed depends on your device. A modern laptop usually converts video faster than real time. Changing only the container (for example MOV with H.264 to MP4) is almost instant because the video is copied, not re-encoded.
Frequently asked questions
Is it free to convert MP3 to WAV?
Yes. You can convert MP3 to WAV for free, 3 files at a time up to 250 MB each, with no sign-up and no watermark. Pro removes the file limit, handles files up to 2 GB and downloads everything as one ZIP.
Are my files uploaded to a server?
No. Vidverter runs entirely in your browser and uses your device's own video encoders. Files never leave your computer or phone, so it is safe for private recordings, and there is no upload or download wait.
Which browsers work?
Current versions of Chrome, Edge, Safari and Firefox on Windows, Mac, iPhone and Android. Chrome and Edge are the fastest because they use hardware video encoders on most computers.
