M4A (AAC) is the sound format of Apple devices: a bit better quality than MP3 at the same size.
Frequently asked questions
Is the sound re-encoded?
With “Same as original” the sound track is copied unchanged when the video already contains it in this format; otherwise it is converted with high quality.
Can I cut out just one song or phrase?
Yes. Play the video in the preview, press “Start here” and “End here” at the right moments, then Start.
Is it free?
Yes, free and without sign-up. Very long videos are limited; choose a part with Start and End.
