Add Music to Video puts a song, a voice-over or any audio file on a video. Keep the original sound with the music underneath, or replace it completely. Set the music’s volume and the moment it starts, let it repeat to the end and fade out. The picture is copied without re-encoding, so the quality does not change. It runs in your browser and nothing is uploaded.
How to add music to a video
- Choose a video: MP4, MOV, WebM or MKV.
- Choose the Music or audio file: MP3, WAV, M4A, FLAC or OGG.
- Under Original sound, pick Keep it, music underneath or Replace it with the music.
- Set the Music volume (and the Original volume when you keep it).
- Type when the Music starts at, and choose whether it repeats and fades out.
- Click Add music, check the result, then Download.
Settings for common videos
| Video | Original sound | Music volume |
|---|---|---|
| Vlog, tutorial or talking to camera | Keep it | 25–35% |
| Holiday clips, travel, sport | Keep it | 50–75% |
| Slideshow, timelapse, screen capture | Replace it | 100% |
| Video with noise you want gone | Replace it | 100% |
Good to know
- The result is MP4 with AAC sound for H.264, HEVC, VP9 and AV1 videos, and WebM with Opus for VP8 videos.
- Because the picture is not re-encoded, a long video is done in seconds, not minutes.
- To mix several sound tracks first, use the Audio Mixer. To cut a song down, use the Audio Cutter. To remove the sound only, see Mute Video.
