What changes from MP3 to WAV

Sound qualityNo further loss (what MP3 already left out doesn’t come back)
Tags and cover artTitle, artist, album and cover carried over where WAV holds them; lyrics and some rarer tags aren’t yet
File sizeUsually larger: WAV compresses less tightly than MP3

When to use WAV: Recording, editing and mastering, and sound effects for video and games.

Questions

How do I convert MP3 to WAV?

Drop your MP3 file on this page, or choose it. Anyfile converts it on your device in a moment and the WAV downloads straight away. To change it first, open it in the audio editor.

Is my MP3 file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Can I convert several MP3 files at once?

Yes. Drop them together and you get one ZIP with every WAV inside.
