Frequently asked questions
Should I choose WAV or MP3?
Choose WAV if you will edit the sound or send it to a transcription app, because it keeps the sound exactly as it is in the video. Choose MP3 if you just want to listen or share it; see MP4 to MP3.
Why is the WAV file so big?
WAV stores sound without any compression, so a long video makes a large WAV file. That is normal.
Does it work with MOV videos from an iPhone?
Yes. MOV videos work here too, because FilesAll only reads the sound, not the picture.
What if my video has no sound?
FilesAll checks first and tells you if the video has no sound, so you do not end up with an empty file.
Can I convert a long video on my phone?
Yes, but the WAV can be large, so make sure your phone has enough free space for it.
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.
