You can add sound to Google Slides in three ways: upload an audio file, insert a YouTube video with sound, or record audio directly in the slide

The simplest method is to upload an MP3 or other audio file you already have. Open your presentation, click the slide where you want the sound, go to Insert > Audio, then choose Upload from computer. Select your file and it will appear as a small speaker icon on the slide. During the presentation, click the icon to play the sound.

If you want background music or a sound that plays automatically, insert a YouTube video instead — even if it's just an audio track uploaded to YouTube. Click Insert > Video, search for the video, and select it. You can then set it to play automatically when the slide appears, and adjust the volume. This method gives you more control over playback timing.

The third option is to record audio directly into Google Slides using your computer's microphone. Go to Insert > Audio > Record audio, then speak or play sound near your microphone. Google Slides will save the recording as a file attached to that slide.

Key Takeaways

  • Upload audio files (MP3, WAV, OGG, M4A) by clicking Insert > Audio > Upload from computer, and the sound will appear as a clickable speaker icon on your slide.
  • YouTube videos with sound can be inserted and set to play automatically when you reach that slide, giving you more playback control than a static audio file.
  • You can record audio directly into a slide using your computer's microphone through Insert > Audio > Record audio.
  • Audio files and videos do not play during slide editing — you must start the presentation to hear them, either in presentation mode or speaker view.
  • File size and format matter: Google Slides accepts MP3, WAV, OGG, and M4A audio, but very large files may take time to upload.

Uploading an audio file from your computer

This is the most direct way to add sound if you already have an audio file saved. Open your presentation and click on the slide where you want the sound to appear. Then click Insert in the menu bar, select Audio, and choose Upload from computer. A file browser will open — navigate to your audio file and click Open.

Google Slides accepts MP3, WAV, OGG, and M4A files. The audio will appear as a small speaker icon on your slide. You can drag this icon to reposition it, or resize it by dragging the corners. During your presentation, click the speaker icon to play the sound. The audio will play through your computer's speakers or headphones.

One limitation: uploaded audio files do not play automatically. You must click the icon each time you want to hear the sound. If you need sound to start playing as soon as you reach a slide, use a YouTube video instead.

Using YouTube videos for automatic playback

If you want music or sound to play automatically when a slide appears, insert a YouTube video. This works even if the video is just an audio track — many people upload music-only videos to YouTube specifically for this purpose. Click Insert > Video, then search for the video by title or paste a YouTube link.

Once you insert the video, right-click it and select Video options. Check the box for Autoplay when presenting if you want the sound to start automatically. You can also adjust the Start at time if you want to skip the beginning, and set the volume level. These settings only affect presentation mode — the video will not autoplay while you are editing.

The video will appear as a thumbnail on your slide. During your presentation, it will play at the size you set. This method gives you more control than a simple audio file, but the video thumbnail takes up more space on the slide.

Recording audio directly into a slide

Google Slides lets you record audio using your computer's built-in or external microphone. Click Insert > Audio > Record audio. A recording window will open with a red record button. Click to start recording, speak or play sound near your microphone, then click the stop button when finished.

Google Slides will save the recording and attach it to your slide as a speaker icon, just like an uploaded file. You can re-record by clicking the icon and selecting Replace, or delete the recording and start over. This method is useful for adding narration, instructions, or personal messages to specific slides.

Recording quality depends on your microphone. A built-in laptop microphone will work but may pick up background noise. If you plan to record multiple slides, consider using an external USB microphone for better sound quality.

Controlling when and how sound plays during presentation

Audio files and YouTube videos behave differently during a presentation. Uploaded audio files require you to click the speaker icon each time — they will not play on their own. This gives you full control over when the sound starts, which is useful if you want to pause and discuss something before playing the audio.

YouTube videos can be set to autoplay, meaning they start as soon as you navigate to that slide. You can also mute the video, adjust volume, or pause it during the presentation. If you want sound to play automatically but do not want a video thumbnail visible, this method has a drawback — the video will still appear on the slide.

In both cases, the sound will only play when you are in presentation mode or speaker view. Editing the slide will not produce any sound, so you can work without audio distracting you.

File formats and size limits

Google Slides accepts audio in MP3, WAV, OGG, and M4A formats. If your audio file is in a different format (like FLAC or WMA), you will need to convert it first using a free tool like Audacity or an online converter. Most audio editing software can export to MP3, which is the most widely supported format.

Google does not publish a strict file size limit for audio, but very large files (over 100 MB) may take a long time to upload or cause performance issues. If your audio file is very large, consider compressing it or splitting it into smaller segments. YouTube videos have no practical size limit since they are hosted on YouTube's servers, not stored in your Google Slides file.

Troubleshooting audio that will not play

If your audio is not playing during a presentation, first check that you are in presentation mode. Audio will not play while you are editing — you must click the presentation button (or press Shift + F5) to start the slideshow. Once in presentation mode, click the speaker icon to play uploaded audio, or wait for YouTube videos to autoplay if you enabled that setting.

If the audio still does not play, check your computer's volume settings and make sure your speakers or headphones are connected and turned on. If you are presenting remotely using Google Meet or Zoom, audio from Google Slides may not transmit to your audience — you may need to use your presentation software's built-in audio sharing feature instead. Test your audio setup before presenting to a group.

Frequently Asked Questions

Can I make audio play automatically without using a YouTube video?

No, uploaded audio files in Google Slides require you to click the speaker icon to play. Only YouTube videos can be set to autoplay. If you need automatic sound, insert a YouTube video or audio track instead of uploading a file directly.

Will my audience hear the audio if I present over Zoom or Google Meet?

Not automatically. When you share your screen in Zoom or Meet, audio from Google Slides may not transmit. You will need to enable audio sharing in your meeting software — in Zoom, check "Share computer sound" when you start screen sharing. Test this before your presentation.

What audio formats does Google Slides support?

Google Slides accepts MP3, WAV, OGG, and M4A files. If your audio is in another format like FLAC or WMA, convert it to MP3 using free software like Audacity or an online converter before uploading.

Can I edit or trim audio after uploading it to a slide?

No, Google Slides does not have built-in audio editing tools. If you need to trim, cut, or adjust your audio, edit the file in a separate program like Audacity before uploading it to your slide.

Does the audio file get stored in my Google Drive?

Yes, uploaded audio files are stored in your Google Drive as part of your presentation. YouTube videos are not stored — they stream from YouTube when you play them. This means uploaded audio will work offline, but YouTube videos require an internet connection.
