How to add music to a video (or replace its audio)
Lay a soundtrack over a clip, or swap its audio entirely — with volume control, free and without uploading.
The right music changes how a video feels. Whether you're scoring a montage, adding background music to a slideshow, or replacing noisy on-location audio, adding a soundtrack is straightforward.
Add your video and a track
Drop a clip into the Add Music tool, then choose a music file — MP3, WAV, M4A and more work.
Replace or mix
Replace swaps the audio entirely; Mix lays the music over the original sound. Set the music volume to taste.
Export
Combine the video and music into one file and download it.
Replace vs mix
Choose Replace when the original audio is unwanted — wind, background noise, or a silent clip. Choose Mix to keep dialogue or ambient sound and add music underneath it. The music is trimmed to the length of the video automatically.
Where to get music
Use tracks you have the rights to — royalty-free libraries, music you've licensed, or your own recordings. Copyrighted songs can get a video muted or taken down on most platforms.
