Adding audio to Google Slides in three steps

Google Slides lets you insert audio files directly into your presentation, and the music plays when you reach that slide during a presentation. You upload the file from your computer, choose when it starts playing, and control the volume. The audio stays embedded in your presentation file, so it travels with you — you do not need to carry separate music files to your presentation.

The process takes about two minutes once you have your audio file ready. Google Slides accepts MP3, WAV, OGG, and M4A files, and the file size limit is 100 MB. If your music file is larger than that, you will need to compress it or trim it before uploading.

Key Takeaways

  • Google Slides embeds audio directly into your presentation, so the music file travels with the slideshow and plays on any device where you open it.
  • Audio files must be MP3, WAV, OGG, or M4A format and cannot exceed 100 MB in size.
  • You insert audio through the Insert menu, then adjust when the sound starts and how loud it plays using the audio icon that appears on your slide.
  • Audio plays only during a live presentation or when you manually click the play button in edit mode — it does not auto-play when someone opens the file.
  • If you want background music across multiple slides, you will need to insert the same file on each slide and time them to overlap.

Prepare your audio file before you start

Before opening Google Slides, make sure your audio file is in one of the supported formats: MP3, WAV, OGG, or M4A. If you have a file in a different format — like WMA or FLAC — you will need to convert it first. Free conversion tools like CloudConvert or Audacity can do this in a few minutes.

Check the file size as well. If it is larger than 100 MB, trim the audio or reduce the quality. Most presentation music does not need high quality — 128 kbps MP3 is standard and keeps file sizes small. Audacity (free, works on Windows and Mac) lets you trim audio and export at lower bitrates without much effort.

Save your final audio file somewhere you can find it easily — your Downloads folder or Desktop works fine. You will need to locate it during the upload step.

Insert audio through the Insert menu

Open your Google Slides presentation and navigate to the slide where you want the music to start. Click the Insert menu at the top, then scroll down and click Audio.

A dialog box opens with two options: Upload and Search. Click Upload to add a file from your computer. A file browser window appears — navigate to your audio file, select it, and click Open. Google Slides uploads the file and places a small speaker icon on your slide.

The upload usually takes 10 to 30 seconds depending on file size and your internet speed. You will see a progress indicator while the file uploads. Once it finishes, the speaker icon appears on the slide and the audio is now part of your presentation.

Position and configure the audio icon

The speaker icon that appears on your slide can be moved anywhere — drag it to a corner, hide it behind a shape, or place it where you want it visible. During a presentation, clicking this icon plays the audio. In edit mode, you can also click it to preview the sound.

Right-click the speaker icon to open a menu with playback options. You can set the audio to Autoplay (starts automatically when the slide appears during a presentation), adjust the Volume with a slider, and choose whether the audio Loops (repeats continuously). Most presentations use autoplay so the music starts without you having to click anything.

If you want the audio to play silently in edit mode but only during a live presentation, leave autoplay on. The audio will not make sound when you are editing or previewing — it only plays when you present to an audience.

Extend music across multiple slides

Google Slides does not have a built-in way to play one audio file across multiple slides. If you want background music that continues from one slide to the next, you have two options: insert the same file on each slide and time them to overlap, or use a shorter music clip that fits within a single slide's display time.

To repeat music across slides, insert the audio on the first slide, note how long it plays, then insert it again on the next slide a few seconds before the first one ends. This creates overlap so there is no silence between slides. It is not seamless, but it works for presentations where you control the pacing and can pause between slides to let the audio catch up.

A simpler approach: use a single music file that is short enough to fit within the time you spend on one slide. A 30-second intro track or a 60-second background loop works better than trying to stitch multiple slides together.

Test your audio before presenting

Always test the audio in presentation mode before you show it to an audience. Click the Present button (or press Ctrl+Enter on Windows, Cmd+Enter on Mac) to start a full-screen presentation. Navigate to the slide with audio and verify that it plays at the right volume and at the right time.

Pay attention to the speaker icon position — if it is visible on your slide, the audience will see it. If you want it hidden, move it off the visible area or place it behind a shape. Test on the actual device and projector you will use if possible, because audio levels and speaker quality vary.

If the audio does not play during the test, check that autoplay is turned on. Right-click the speaker icon again and confirm the Autoplay option is selected. If autoplay is on and the audio still does not play, try downloading the presentation as a PowerPoint file and opening it in Google Slides again — sometimes a refresh fixes playback issues.

Troubleshooting common audio problems

If your audio file will not upload, the most common reason is file size or format. Check that your file is under 100 MB and in MP3, WAV, OGG, or M4A format. If it is a different format, convert it first using a free tool like CloudConvert.

If the audio plays but is too quiet or too loud, right-click the speaker icon and adjust the volume slider. Google Slides volume is separate from your computer's system volume, so even if your computer is loud, the presentation audio might be set low.

If you are presenting and the audio does not play, check that your computer's speakers are turned on and not muted. Also confirm that you are in presentation mode — audio only plays during a live presentation or when you click the speaker icon in edit mode, not when you are just viewing the slide normally.

Frequently Asked Questions

Can I use music from YouTube or Spotify in my Google Slides?

No — you cannot embed YouTube videos or Spotify streams directly into Google Slides. You must read the audio as a file first. For music you own or have permission to use, read it as an MP3 and then insert it. For copyrighted music, check the licensing terms before using it in a presentation, especially if you are presenting publicly.

What happens to the audio if I share my presentation with someone else?

The audio file stays embedded in the presentation, so anyone you share it with can hear it. They do not need to read anything separately. If you share the presentation link, they can open it and play the audio. If you read it as a PowerPoint file, the audio comes along with it.

Can I record my own voice and add it to a slide?

Yes — record your voice as an MP3 or WAV file using a free tool like Audacity, then insert it the same way you would insert music. You can also use Google Slides' built-in recording feature by clicking Insert, then Audio, then Record to capture audio directly without leaving the presentation.

Why does my audio play in edit mode but not during a presentation?

Check that autoplay is turned on. Right-click the speaker icon, look for the Autoplay option, and make sure it is selected. If autoplay is on and the audio still does not play, try refreshing the page or re-uploading the file. Also confirm your computer speakers are not muted.

Can I add different music to different slides?

Yes — insert a separate audio file on each slide. Each file plays independently when you reach that slide during a presentation. This works well if you want different background music for different sections of your presentation.
