How it works
- Upload a video
Tap Upload video and pick an MP4, MOV, WebM or another video, up to 2 GB.
- Pick the music
The editor opens on Sound. Tap Change soundtrack and choose an MP3, M4A, WAV, OGG or FLAC file, or a video, up to 200 MB.
- Mix and save
Mix plays the music over the video’s own sound; Replace plays only the music. Set the Music volume, then tap Mix sound now or Replace sound now.
Hear it before you save
The music plays with the video in the preview right away. Move Starts at to begin later in the song, for example at the chorus.
Fits the length of the video
The music ends with the video. A shorter song repeats until the end (Repeat if shorter), and the last 2 seconds fade out (Fade out at the end) — turn either off with one tap.
The picture stays as it is
When you only change the sound, and cut nothing from the start, the picture is copied without re-encoding, so it looks exactly the same. WebM videos in the older VP8 format, and a few other formats that MP4 can’t hold, are re-encoded at good quality instead.
Your original stays
The video with music is a new MP4 with its own link and a Download button. The original video and its sound do not change.
Add music to video: questions
How do I add music to a video?
Upload the video, tap Change soundtrack under Sound and pick the song. Keep Mix to hear the video’s own sound too, or choose Replace. Then tap Mix sound now or Replace sound now.
Can I keep the original sound under the music?
Yes. Mix plays the music over the video’s own sound. Set the Music volume from 0 to 200 %, and the volume of the video above it.
Which music files work?
MP3, M4A, WAV, OGG and FLAC, or a video file — then its sound is used. The file can be up to 200 MB.
What if the song is longer than the video?
It stops at the end of the video. With Fade out at the end, the last 2 seconds get quieter instead of cutting off.
Is it free?
Yes. No sign-up and no watermark.
