What changes going from MP3 to WAV
- Because WAV is uncompressed, the file will be far larger than the MP3 (roughly 10 MB per minute of stereo), and that's expected.
- A WAV can't add detail the MP3 never had, but editors and DAWs open it without any decoding trouble.
MP3 and WAV in brief
- MP3 is the audio format that plays on every phone, car stereo, speaker, editor and website. It's lossy, which keeps files small.
- WAV is raw, uncompressed audio: perfect quality, but around 10 MB for every minute of stereo. Editors, DAWs and some upload forms want WAV.
Mac tips
- It runs the same on Apple silicon and Intel Macs, with nothing to get from the App Store.
- Decoding uses your browser's own audio support. If one browser can't open the file, try Chrome or Firefox.

Questions & answers
Will MP3 to WAV make it sound worse?
No. WAV is uncompressed, so nothing more is lost.
Can I trim the audio while I'm at it?
Yes. Drag the start and end handles on the waveform, play it back, and add a fade in or fade out if you like.
Do my recordings get sent anywhere?
No. Your browser does the conversion with your device's own processor, so your recordings stay with you. Once the page has loaded you could even switch off your internet connection.
Where do I find the converted file on my Mac?
Click Download. You'll find the file in your Downloads folder (in Finder or on the Dock).
