Frequently asked questions
Will converting to WAV make my MP3 sound better?
No. A WAV made from an MP3 sounds the same as the MP3. It is useful when an app or device needs WAV, not to improve the sound.
Why is the WAV file so much bigger?
WAV stores sound without any compression, so it is often about ten times the size of the MP3. That is normal.
When do I need a WAV file?
Some audio editors, CD burning apps, phone systems and older devices only accept WAV. WAV is also handy for editing without losing more quality each time you save.
Can I convert many MP3s at once?
Yes. Add them all, then use Download all to save the WAV files in one ZIP file.
Can I make a WAV from a video?
Yes. Use MP4 to WAV to save the sound from a video as a WAV file.
Is FilesAll free?
Yes. You can use FilesAll free every day without signing up, and the tool shows how many free files you have left today. A free account gives you more each day, and Pro removes the daily limit.
Do I need to install anything?
No. FilesAll works in the web browser you already have, on Windows, Mac, Chromebook, iPhone and Android. There is nothing to install, and you do not need an account to start.
Are my files uploaded?
No. FilesAll does all the work inside your browser, on your own device. Your files are never sent to our servers or anyone else's, and they disappear when you close the tab.
