How to add music to a video
- 1
Drop your video
MP4, MOV, WebM or MKV — with or without sound.
- 2
Choose your song
MP3, M4A, WAV or OGG. Drag "Start the song at" to land on the best part.
- 3
Balance the sound
Set the music volume and how much original sound to keep — 0% replaces it.
- 4
Export
Music and video are mixed in one pass, ready to share.
Popular ways to use it
Reels and TikToks
Add a track and stack "Resize for social" for a 9:16 video in the same export.
Travel videos
Replace wind noise with calm music by setting the original sound to 0%.
Birthday and wedding clips
Merge several clips and run one song across all of them.
Product videos
Soft music under your voice-over: music at 25%, original at 100%.
Tips for the best result
- Keep music around 20–30% under speech so voices stay clear.
- A 2-second fade-out at the end sounds far more polished than a hard cut.
- Only use music you have the rights to if you post publicly.
Add music — FAQ
Can I replace the original sound completely?
Yes — turn "Original sound" down to 0% and only the music is kept.
What if the song is shorter than the video?
Leave "Loop the song" on and it repeats until the video ends, with a fade-out at the very end.
Which audio formats can I use?
MP3, M4A (AAC), WAV and OGG work in every modern browser; FLAC works in most.
Will adding music reduce video quality?
The video is re-encoded once at high quality. Add "Compress" if you also need a smaller file.
Can I add music to a silent video?
Yes — the video gets a brand-new soundtrack from your song.
