How do I convert an MP4 to MP3 without uploading it?
To convert an MP4 to MP3 without uploading it, open FilesAll's MP4 to MP3 and add a video from your device. FilesAll shows the length and the expected MP3 size, then saves only the sound as an MP3 that plays in any music app. It all runs in your browser, on your own device.

Frequently asked questions
Can I convert a YouTube video to MP3?
No. FilesAll does not download anything from YouTube or other websites. It only works with video files that are already on your phone or computer.
Will the MP3 be as long as the video?
Yes. The MP3 has the same length as the video, from start to finish. Only the picture is left out.
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 MP3.
Can I convert a long video on my phone?
Yes. FilesAll reads the sound a piece at a time instead of loading the whole video, so long videos do not fill up your phone's memory.
My video is a MOV from an iPhone. Does that work?
Yes. MOV videos work here too. For more about iPhone and Mac videos, see MOV to MP3.
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.
