Good to know
MP3 is the most widely supported audio format. Its lossy compression removes sounds people barely hear, keeping files small, and it plays on virtually every phone, car stereo and speaker.
WAV stores audio uncompressed. There is zero quality loss, which is why editors and studios use it, but it takes roughly 10 MB per minute.
Converting MP3 to WAV produces uncompressed audio for editors and broadcast or video tools that only accept WAV. Lost detail does not come back, and the file gets larger.
Conversion runs inside this browser and files are never sent over the internet. Because your phone or computer does the work, long videos may take a little while.
FAQ
Does MP3 to WAV improve quality?
No. Sound removed by MP3 compression cannot be restored; you convert for compatibility with editing software.
Are my files uploaded?
No. Every conversion runs in your browser on your own device.
Does it work with long videos?
Yes, but it uses your device’s power, so a one-hour video may take a few minutes, and files over 2 GB may fail on phones.
