There are four common ways to add music to a video on iPhone. The right one depends on where the video is going.
The comparison
| Method | Cost | Control | Best for |
|---|---|---|---|
| iMovie | Free (Apple) | Full: volume, fades, timing | One video, any destination |
| Photos Memories | Built in | Low | Quick photo and video montages |
| CapCut | Free with paid tiers | Full, plus beat sync | Social edits, Reels, TikTok |
| Instagram or TikTok music | Free in-app | Basic | Posting directly to that platform |
iMovie
Add your video, tap + > Audio > Soundtracks, and add a track. Adjust volume and fades with the Audio button. No watermark. Step-by-step.
Photos Memories
Photos only adds music to Memories (automatic slideshows), not single clips. Fast, but you get little control. How it works.
CapCut
Good for timing cuts to the beat of the music. Add audio, then use beat markers to line up edits. Check export settings for watermarks.
Add music when you post
If the video is going to Instagram Reels or TikTok, the platform's own music library is often the best option, because those tracks are licensed for use on that platform. Add the song in the app's editor right before posting.
The licensing rule of thumb
- Posting to a platform: use that platform's library.
- Posting anywhere else, like your website or YouTube: use royalty-free music or iMovie Soundtracks.
- Never assume a popular song is fine just because you bought it. Owning a song doesn't give you the right to publish it in a video.
