Add music to a video

The picture is copied as-is, so there is no quality loss and it is fast. The sound is mixed in your browser and encoded as AAC. Videos with no sound at all work too — the music becomes the soundtrack.

Frequently asked questions

Will the video quality change?

No. Only the audio is created again; the video stream is copied.

What if the music is shorter than the video?

Turn on Loop to repeat it, or it will stop when it ends.

Can I use any song?

Only music you have the rights to use, such as your own or properly licensed tracks.
