The fastest way to add music to your iMovie project

Open your project in iMovie, click the Music and Sound Effects button in the toolbar (it looks like a musical note), then drag a track from the results into your timeline. iMovie will place it on a separate audio track below your video. If you want to use a song from your own files instead of iMovie's built-in library, click Music in the sidebar, then My Music, and drag the file in the same way.

The whole process takes under a minute. The harder part is usually deciding where the music should start and stop, and whether it needs to be quieter during dialogue. Both of those are adjustable after you've placed the track.

Key Takeaways

  • iMovie's built-in music library is free and royalty-free, so you can use any track in your finished video without worrying about copyright.
  • You can add your own music files by dragging them from your Mac's Music app or Finder directly into the timeline.
  • Each audio track sits separately in the timeline, so you can adjust the volume of music independently from dialogue or other sounds.
  • Fade-in and fade-out handles appear at the edges of each audio clip, letting you control how abruptly the music starts and stops.
  • If music plays over dialogue, you can lower its volume by selecting the track and dragging the volume slider in the inspector panel.

Using iMovie's built-in music library

When you click the Music and Sound Effects button, iMovie shows you its entire royalty-free music collection organized by mood and genre. You'll see categories like "Cinematic," "Upbeat," "Dramatic," and "Ambient." Each track is short — usually between 30 seconds and two minutes — so they're designed to loop or to fill a specific scene rather than carry an entire project.

Preview a track by clicking it; the audio plays at normal volume so you can hear how it sounds. Once you've found one you like, drag it directly onto your timeline. If you drag it onto the video track itself, iMovie will create a new audio track below it automatically. If you drag it onto an empty area below the video, it lands on its own track.

The advantage of iMovie's library is that every track is cleared for use in any finished video — YouTube, social media, client work, anything. You don't have to check licenses or worry about copyright strikes. The disadvantage is that the selection is limited and the tracks are recognizable if you use iMovie frequently.

Adding your own music files

If you have an MP3, WAV, or M4A file on your Mac, you can add it to iMovie without using the built-in library. The easiest route is through your Music app: open Music, find the song you want, and drag it directly into your iMovie timeline. iMovie will import it and place it on a new audio track.

If the file isn't in your Music app, open Finder, navigate to the folder where the file lives, and drag it into the timeline the same way. iMovie accepts most common audio formats. If you're working with a file from a streaming service or a protected purchase, iMovie may not be able to import it — those files usually have copy protection that prevents editing software from reading them.

One important note: if you're using music you didn't create yourself, you need to own the rights to use it in your video. That means either you made it, you bought a license to use it, or the creator gave you permission. iMovie doesn't check this for you; it's your responsibility before you publish.

Positioning and timing your audio tracks

Once a music track is in your timeline, you can move it left or right to change when it starts playing. Click and drag the track itself to slide it earlier or later. You can also trim the beginning or end by dragging the small handles at the edges of the clip — the left handle controls where the music starts, and the right handle controls where it ends.

If you want the music to fade in gradually instead of starting at full volume, position your cursor at the very start of the audio clip until you see a small curved handle appear. Drag that handle to the right to create a fade-in effect. Do the same at the end of the clip to fade out. The longer you drag, the longer the fade takes.

You can layer multiple audio tracks on top of each other. If you have dialogue on one track and music on another, both will play at the same time. This is useful for adding background music under a voiceover, but it means you'll need to adjust volumes so one doesn't drown out the other.

Adjusting volume and balancing multiple audio tracks

Select an audio track by clicking it once. A panel appears on the right side of the screen showing the track's details. You'll see a Volume slider — drag it left to make the track quieter, or right to make it louder. The slider goes from 0% (silent) to 100% (full volume).

If you have music playing over dialogue, a common approach is to set the music to 30–50% volume so the voice stays clear. You can also create a volume curve by clicking the audio track and selecting Show Volume Levels from the inspector — this lets you make the music quieter in one section and louder in another without splitting the clip.

Test your mix by playing the project. Use your Mac's volume control or your headphones to hear how the dialogue, music, and any other sounds work together. If one element is too loud or too soft, select that track and adjust its volume slider until the balance feels right.

Removing or replacing audio tracks

If you want to delete a music track entirely, click it once to select it, then press Delete. The track disappears and the timeline closes the gap. If you want to replace it with a different song, you can either delete it and add a new one, or you can right-click the track and select Replace to swap it out while keeping the same position and timing in your timeline.

If you accidentally delete a track, use Edit > Undo or press Command+Z to bring it back. iMovie keeps your last several edits in the undo history, so you can step back multiple times if needed.

Exporting your project with audio

When you're ready to save your video, go to File > Share and choose where you want to send it — YouTube, Apple TV, or your Mac as a file. iMovie will export the video with all your audio tracks mixed together. The music, dialogue, and any other sounds will be combined into a single audio track in the finished file.

If you're exporting to a file on your Mac, iMovie gives you quality options. For most purposes, the default settings work fine. The export process can take a few minutes depending on your video's length and your Mac's speed.

Frequently Asked Questions

Can I use music from Spotify or Apple Music in iMovie?

Not directly. Spotify and Apple Music files have copy protection that prevents iMovie from importing them. If you own the song or have a license to use it, you can read an unprotected version and add that instead. Some artists sell DRM-free versions on Bandcamp or other platforms.

What if the music is longer than my video?

Drag the right edge of the audio track to the left to trim it. The music will stop at that point. You can also fade it out gradually by creating a fade-out handle at the end, which sounds more natural than an abrupt stop.

Can I adjust the volume of just one part of a music track?

Yes. Select the audio track, then in the inspector panel select Show Volume Levels. Click on the audio waveform where you want to change the volume, and a point appears. Drag that point up or down to raise or lower the volume at that moment. You can create multiple points to shape the volume curve however you want.

Will my video get flagged for copyright if I use iMovie's built-in music?

No. iMovie's music library is royalty-free, meaning the copyright holders have already given permission for anyone to use these tracks. You can publish videos with this music on YouTube, social media, or anywhere else without copyright claims.

What audio formats does iMovie accept?

iMovie works with MP3, WAV, M4A, AIFF, and several other common formats. If you have an unusual file type, try converting it to MP3 using a free tool like Audacity or CloudConvert, then import the converted version into iMovie.
