How to convert MP4 to MP3
- Drop your MP4 file on the box above, or tap it to choose. You can pick several files at once.
- MP3 is already selected. Adjust the quality if you like (192 kbps is a good default, 320 kbps for the best quality).
- Tap the download button next to each file. Your MP3 is saved to your Downloads folder.
Pull the music, speech or lecture audio out of a video you recorded or downloaded, without uploading the video anywhere. MOV files from iPhones often work too.

Frequently asked questions
How big a video can I use?
The whole video is read into your device's memory, so on a phone keep it under a few hundred MB. Computers can handle larger files.
Can I convert a YouTube link?
No. This tool works with video files on your device. Converting other people's videos may also break the site's terms or copyright.
Does it work with MOV, MKV or AVI?
MP4 and most iPhone MOV files work. MKV and AVI depend on your browser and usually don't.
Can I convert several files at once?
Yes. Choose or drop as many files as you like. They are converted one after another and each gets its own download button.
Are my files uploaded?
No. The conversion runs inside your browser on your own device. Your audio is never sent to a server, so it works with private and unreleased recordings.
Is it really free?
Yes. No sign-up, no watermark, no daily limit. Very long files (over about an hour) may be too big for a phone's memory.
