Get the audio out of a MP4 video
Vidverter takes the soundtrack of your MP4 file and saves it as MP3, leaving the video behind. Handy for lectures, interviews, podcasts recorded on video, voice memos and music from your own recordings.
MP3 is the universal audio format: every phone, car stereo, speaker, editor and website plays it. At 192 kbps it sounds great for music and speech while staying small.
Choosing the audio quality
- 128 kbps: speech, podcasts, voice notes (about 1 MB per minute).
- 192 kbps: recommended for music (about 1.4 MB per minute).
- 320 kbps: highest MP3 quality for archiving music.
Good to know
- Only convert recordings you own or have permission to use.
- Processing speed depends on your device. A modern laptop usually converts video faster than real time. Changing only the container (for example MOV with H.264 to MP4) is almost instant because the video is copied, not re-encoded.
Frequently asked questions
Is it free to extract MP3 audio from MP4?
Yes. You can extract MP3 audio from MP4 for free, 3 files at a time up to 250 MB each, with no sign-up and no watermark. Pro removes the file limit, handles files up to 2 GB and downloads everything as one ZIP.
Are my files uploaded to a server?
No. Vidverter runs entirely in your browser and uses your device's own video encoders. Files never leave your computer or phone, so it is safe for private recordings, and there is no upload or download wait.
Which browsers work?
Current versions of Chrome, Edge, Safari and Firefox on Windows, Mac, iPhone and Android. Chrome and Edge are the fastest because they use hardware video encoders on most computers.
