Frequently asked questions
What is the difference between WAV and MP3?
WAV keeps the sound exactly as recorded, so files are very large. MP3 leaves out sound most people can't hear, so files are much smaller and easy to send.
Will my audio sound worse?
At the standard setting most people can't hear a difference for speech and everyday music. For music you will edit later, keep the WAV too.
Are my WAV files changed?
No. FilesAll makes new MP3 files and leaves your WAV files as they were.
Can I convert recordings from a voice recorder?
Yes. Many voice recorders and audio apps save WAV files, and they convert the same way.
Can I turn an MP3 back into a WAV?
Yes, with MP3 to WAV. The sound left out of the MP3 does not come back, though.
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.
