The simplest way to add music to a slideshow

The fastest route depends on what you already have. If you are using PowerPoint, Google Slides, or Keynote, the music goes in through the Insert menu on each slide or across the whole presentation — you upload an audio file, set it to play automatically, and adjust the volume. If you are using a dedicated slideshow tool like Canva or Adobe Express, music is built into the library and you search by mood or length, then drag it onto your timeline. If you have a folder of photos and want to turn them into a video-style slideshow with music, Windows Photos (on Windows) or Photos (on Mac) can do this in under five minutes without installing anything.

The choice between these routes comes down to one question: do you need the slideshow to be editable later, or do you need it to be a finished file you can share? Editable slideshows live in PowerPoint, Google Slides, or Keynote. Finished files — videos you can email or post — come from video editors or the built-in photo apps. Most people start with an editable slideshow and export it as a video only if they need to share it outside their organization.

Key Takeaways

  • PowerPoint, Google Slides, and Keynote all add music through the Insert menu, and the music syncs to your slide timing automatically.
  • If you are using Canva or Adobe Express, search the built-in music library by mood or length instead of uploading your own file.
  • Windows Photos and Mac Photos can turn a folder of images into a finished video with music in minutes, with no editing needed.
  • Music files must be in a common format — MP3, WAV, or M4A — and most tools limit file size to 100 MB or less.
  • If your music is longer than your slides, the slideshow will loop the audio or cut it off depending on the tool, so test before presenting.

Adding music in PowerPoint

Open your presentation and go to the slide where you want the music to start. Click the Insert tab at the top, then click Audio and choose Audio on My PC. Navigate to your MP3 or WAV file and click Insert. A speaker icon appears on the slide. Right-click it and select Play Settings to choose whether the audio plays automatically when you reach that slide or only when you click the icon during your presentation.

If you want the same music to play across multiple slides, insert it on the first slide, then right-click the speaker icon and select Play Settings again. Check the box that says Play Across Slides. The music will continue playing as you move through slides until it ends or you manually stop it. To adjust volume, right-click the speaker icon and select Edit Audio, or use the volume slider that appears when you click the icon during playback.

PowerPoint does not trim audio inside the presentation, so if your music file is longer than you need, trim it in a free tool like Audacity before inserting it. The audio file must be under 100 MB and in MP3, WAV, M4A, or OGG format.

Adding music in Google Slides

Click the slide where you want music to begin. Go to Insert at the top, then click Audio. You can upload a file from your computer, search Google Drive for a file you have already saved, or paste a URL if the audio is hosted online. Select your file and click Select. A speaker icon appears on the slide.

Click the speaker icon to open the audio options panel on the right side. Under Playback, toggle Autoplay on if you want the music to start automatically when you reach that slide. If you want the audio to continue playing across multiple slides, check Play across slides. You can also adjust the volume slider here. Google Slides does not show a visual timeline for audio, so if your music is longer than your slides, test the presentation in slideshow mode to hear where the audio cuts off.

Google Slides accepts MP3, WAV, M4A, OGG, and FLAC files up to 100 MB. If you are uploading from your computer, the file uploads directly to your presentation and is not stored separately in Drive.

Adding music in Keynote (Mac and iPad)

Click the slide where you want the music to start. Go to Insert at the top, then click Audio. Choose Audio File and navigate to your MP3, WAV, or M4A file on your computer. The audio appears as a speaker icon on the slide. You can drag it to reposition it or make it smaller, though it will not be visible during playback.

Click the speaker icon to open the audio options in the sidebar on the right. Under Audio, you can set the audio to play automatically when the slide appears, or only when clicked. If you want the music to continue across multiple slides, click Continue Playback Across Slides. Adjust the volume with the slider below. Keynote lets you see the audio waveform and trim it directly in the presentation — click the speaker icon and look for the trim handles at the edges of the waveform in the timeline at the bottom of the screen.

Using built-in music libraries in Canva and Adobe Express

Canva and Adobe Express do not require you to upload your own music. Instead, they include libraries of royalty-free tracks organized by mood, genre, and length. Open your presentation in Canva, click Elements on the left sidebar, then search for Music. Browse by category or search by mood — "upbeat", "calm", "dramatic" — and click a track to preview it. Click the track again to add it to your presentation. The music appears on a timeline at the bottom, and you can see exactly how long it is and whether it covers all your slides.

In Adobe Express, click Assets on the left, then Audio. Search by mood or length and preview tracks before adding them. Both tools let you trim the audio by dragging the edges of the audio bar on the timeline, so you can match the music length to your slide duration exactly. This is much easier than uploading your own file and discovering it is too long or too short.

The advantage of these libraries is that all music is already licensed for presentations and videos, so you do not have to worry about copyright. The disadvantage is that you cannot use your own audio files — only the tracks in their library.

Converting a photo folder to a video with music (Windows and Mac)

If you have a folder of photos and want a finished video file with music, the built-in photo apps on Windows and Mac can do this without any additional software. On Windows 10 or 11, open the Photos app, navigate to the folder containing your images, select all the photos you want to include, then click Create at the top and choose Create with Music. The app opens a video editor where you can choose a music track from its library, set the slide duration (how long each photo appears), and add a title. Click Finish Video and the app exports an MP4 file to your Videos folder.

On Mac, open the Photos app, select the photos you want, click File at the top, then Create and choose Slideshow. A window opens where you can choose music from iTunes or Apple Music, set the slide duration, and add transitions. Click Done and the slideshow plays when ready. To save it as a video file, click File again and select Export, then choose a format and location.

This route is fastest if you do not need to edit the slideshow later — you get a finished video file that you can email, upload to YouTube, or play on any device. The trade-off is that you cannot go back and change individual slides or reorder photos without starting over.

Troubleshooting audio that does not sync or play

If your music does not play during a presentation, first check that the audio file is in a supported format. PowerPoint, Google Slides, and Keynote all accept MP3 and WAV, but some older formats like WMA (Windows Media Audio) do not work. Convert the file to MP3 using a free tool like Audacity or VLC Media Player if you are unsure.

If the audio plays but cuts off before your slides end, your music file is shorter than your presentation. Either trim your slides to match the music length, or find a longer track. If you are using a tool that loops audio, check the settings to see if looping is turned on — most tools do not loop by default, so the audio straightforward stops when it reaches the end.

If the audio plays out of sync with your slides — starting late or playing at the wrong time — check that you have set the correct playback settings. In PowerPoint and Google Slides, make sure Autoplay is toggled on if you want the music to start automatically. If you are advancing slides manually, the audio may not stay in sync because you are moving faster or slower than expected. Test the presentation in slideshow mode before presenting to an audience.

Frequently Asked Questions

Can I use music from YouTube or Spotify in my slideshow?

Not directly. YouTube and Spotify music is protected by copyright, and inserting it into a presentation or exporting the presentation as a video violates their terms of service. Use royalty-free music from libraries like Canva, Adobe Express, YouTube Audio Library, or Epidemic Sound instead. These are licensed for presentations and videos.

What happens if my music is longer than my slides?

The audio will continue playing after your slides end. Most tools do not loop the audio automatically, so it straightforward stops when it reaches the end of the file. If you want the music to match your slide duration exactly, trim the audio file before inserting it, or use the trim tools in Canva, Adobe Express, or Keynote to shorten it within the presentation.

Can I have different music on different slides?

Yes. Insert audio on each slide separately, and set each one to play automatically or on click. In PowerPoint and Google Slides, the second audio file will start when you reach that slide, cutting off the previous track. In Keynote, you can see all audio tracks on the timeline and adjust when each one plays.

Do I need to read music files, or can I use links?

Google Slides accepts URLs to audio files hosted online, so you can paste a link instead of uploading. PowerPoint and Keynote require the file to be on your computer or connected storage. If you are using Canva or Adobe Express, you do not need to read anything — the music comes from their built-in library.

What file formats work for audio in presentations?

MP3 and WAV work in all major presentation tools. M4A works in PowerPoint, Google Slides, and Keynote. OGG and FLAC work in Google Slides. Avoid WMA, AIFF, and other older formats — convert them to MP3 first using Audacity or VLC if your tool does not recognize them.
