MP4 vs MP3: what’s the difference?
MP4 is a video format that holds both picture and sound. MP3 is an audio-only format. When you convert MP4 to MP3, the picture is dropped and the sound is kept, which is why the file becomes much smaller.
| MP4 | MP3 | |
|---|---|---|
| Contains | Video + audio | Audio only |
| Typical size for 3 minutes | 20 to 60 MB | 3 to 7 MB |
| Plays in | Video players, galleries | Music apps, car stereos |
Can I upload my own MP4 file?
Not at the moment. This is an audio file converter MP4 to MP3 tool for video links. It works with video links, not files from your computer. If you have an MP4 on your device and want MP3, free desktop players like VLC can do it: open Media → Convert/Save, choose your file, and pick an audio profile.
The same goes for other conversions people ask about, like MKV to MP4, “convert to MP4” from other formats, or video to GIF. This site doesn’t do those file conversions yet. For MKV to MP4, VLC and HandBrake are free and reliable. For video to GIF, most free online GIF makers work well.
