Adding background music to slides in PowerPoint or Google Slides

You can add background music to your slides by inserting an audio file directly into your presentation. In PowerPoint, you upload an MP3 or WAV file and set it to play across multiple slides or just one. In Google Slides, you embed audio through a workaround using Google Drive, since Slides doesn't have native audio support like PowerPoint does. Both methods take about five minutes once you have your audio file ready.

The main difference is that PowerPoint lets you control exactly which slides the music plays on and whether it continues between slides. Google Slides requires you to embed the audio as a playable object on a specific slide, so it works better if you want music on just one slide or as an intro. If you need music throughout a presentation, PowerPoint is the simpler choice.

Key Takeaways

  • PowerPoint lets you insert audio files directly and set them to play across multiple slides or loop continuously.
  • Google Slides requires you to upload audio to Google Drive first, then embed it as a playable object on individual slides.
  • Audio files must be in a format your software supports — MP3 and WAV work in both PowerPoint and Google Slides.
  • You can hide the audio player icon on a slide so the music plays without a visible button, though the method differs between PowerPoint and Google Slides.

Adding background music in PowerPoint

Open your presentation in PowerPoint and go to the slide where you want the music to start. Click the Insert tab at the top, then select Audio (in newer versions) or Audio from This Device (in older versions). Browse to the MP3 or WAV file on your computer and click Insert. A small speaker icon will appear on your slide.

Click the speaker icon to select it, then look at the Audio Tools tab that appears. Under Playback, you'll see options to set when the audio starts. Choose Automatically if you want the music to play as soon as the slide appears, or On Click if you want to start it manually during your presentation. If you want the music to continue playing while you move to the next slide, check the box for Play Across Slides.

To hide the speaker icon so only the music plays, right-click it and select Format Audio. Go to the Size & Properties tab and look for options to hide or make it transparent. In some versions, you can simply drag the icon off the visible slide area or make it very small. Test your presentation in slideshow mode to make sure the audio plays when you expect it.

Adding background music in Google Slides

Google Slides doesn't have a direct audio insert feature, so you'll use Google Drive as a workaround. First, upload your MP3 or WAV file to Google Drive. Right-click the file, select Open with, and choose Google Drive (or it may open automatically). Copy the file's sharing link — you'll need this to embed it.

Go back to your Google Slides presentation and open the slide where you want the audio. Click Insert at the top, then select Embed. Paste the sharing link into the box and click Embed. A playable audio player will appear on your slide. You can resize it by dragging the corners, or move it to a corner of the slide where it won't distract from your content.

The audio player will be visible during your presentation, so this method works best if you want music on just one slide (like a title slide) or if you don't mind the player showing. If you need music across multiple slides in Google Slides, you'll have to embed the same audio on each slide separately, which is why PowerPoint is more practical for full-presentation background music.

Preparing your audio file before you insert it

Make sure your audio file is in a format both programs support. MP3 and WAV files work in PowerPoint and Google Slides. If you have audio in another format (like M4A or FLAC), convert it to MP3 first using a free tool like Audacity or an online converter. Keep the file on your computer or in Google Drive where you can find it quickly.

If your audio file is very long, consider trimming it to just the section you need. A 30-second intro is usually enough for background music on a title slide, and a 2-3 minute loop works well if you want music playing while people settle in before a presentation starts. Shorter files also mean your presentation file stays smaller and uploads faster.

Controlling when music plays and stops

In PowerPoint, you can set the audio to stop automatically after a certain number of slides. Select the speaker icon, go to Audio Tools > Playback, and look for Stop Playing options. You can also set a fade-out effect so the music doesn't cut off abruptly — right-click the speaker icon, select Format Audio, and look for fade options under Audio or Playback.

If you want the music to loop (play repeatedly), check the Loop Until Stopped option in the Playback tab. This is useful if your audio is short and you want it to keep playing while you present multiple slides. Test it in slideshow mode to make sure the looping sounds natural and doesn't create an awkward gap between repeats.

In Google Slides, you have less control — the audio player will play once when clicked, and you'll need to click it again to replay it. If you need looping background music in Google Slides, PowerPoint is the better tool for that specific task.

Troubleshooting audio that won't play

If your audio doesn't play in PowerPoint, check that the file format is supported. PowerPoint works with MP3, WAV, M4A, and a few other formats, but not all audio files are compatible. Try converting your file to MP3 and inserting it again. Also make sure the file isn't corrupted — try playing it in Windows Media Player or another audio app first to confirm it works.

If the audio plays on your computer but not when you share the presentation with someone else, the issue is usually that the audio file isn't embedded in the presentation file itself. In PowerPoint, right-click the speaker icon and look for an option to Embed Audio or Link to File. Make sure Embed Audio is selected so the audio travels with your presentation. In Google Slides, the audio is linked to your Drive file, so anyone you share the presentation with needs permission to access that Drive file.

If you're presenting on a different computer, test the audio before you start. Open your presentation, go to slideshow mode, and play the audio to make sure it works on that machine. Some school or work computers have audio disabled, so check with IT support if the sound won't play in a presentation room.

Frequently Asked Questions

Can I add different background music to different slides?

Yes, in PowerPoint. Insert audio on the first slide where you want it to play, set it to play automatically, and uncheck Play Across Slides. Then insert different audio on another slide. Each audio file will play only on its own slide. In Google Slides, you embed audio on individual slides, so each slide can have its own audio player.

What if my audio file is too large to upload?

Compress your audio file to reduce its size. Use Audacity (free) to export your audio as a lower-quality MP3 — 128 kbps instead of 320 kbps will cut the file size roughly in half and still sound acceptable for background music. You can also trim the audio to remove sections you don't need.

Will the background music play when I share my presentation online?

In PowerPoint, yes, if you embed the audio (not link to it). In Google Slides, yes, but only if the people you share with have permission to access the audio file in your Google Drive. Check your sharing settings to make sure they can view the file.

Can I make the audio player invisible so only the music plays?

In PowerPoint, you can move the speaker icon off the slide or make it very small, but it will still be there. In Google Slides, the audio player is always visible. If you need truly invisible background music, PowerPoint is the better option — move the speaker icon to a corner or off the edge of the slide entirely.

What's the best audio format for presentations?

MP3 is the most reliable choice because both PowerPoint and Google Slides support it, and it's compressed so files stay small. WAV files also work but are much larger. Stick with MP3 unless you have a specific reason to use another format.
