The basic steps depend on which tool you're using

Adding music to a slideshow works differently in each program. PowerPoint, Google Slides, Keynote, and free tools like Canva each have their own menu for inserting audio. The process usually takes two to five minutes once you know where to look — but the location of that button changes from tool to tool.

Before you start, you'll need an audio file on your computer or access to a music library within the program itself. Some tools let you search and insert music directly; others require you to upload a file you already own. Knowing which your tool does will save you a search.

Key Takeaways

  • Most programs insert audio through an Insert or Media menu, but the exact path varies — PowerPoint uses Insert > Audio, Google Slides uses Insert > Audio, and Keynote uses Insert > Audio or Media.
  • You can add music to a single slide or set it to play across multiple slides, depending on your tool and what the slide transition settings allow.
  • Audio file size and format matter: MP3 files work in nearly all tools, while WAV and M4A have more limited support depending on the program.
  • Most tools let you trim the audio length, adjust volume, and hide the audio player icon so the music plays without a visible control on the slide.
  • Test your slideshow on the actual device you'll present from, because audio playback can behave differently between your editing computer and a projector or external monitor.

Adding music in PowerPoint (desktop and online)

In PowerPoint on Windows or Mac, go to the slide where you want the music to start. Click the Insert tab at the top, then find Audio in the ribbon. You'll see two options: Audio on My Device (to upload an MP3 or WAV file from your computer) or Online Audio (to search for music within Office's library). Choose the file or track, and it will appear as a small speaker icon on your slide.

Once inserted, right-click the speaker icon and select Play in Background if you want the music to continue across multiple slides without stopping. This opens a menu where you can choose which slide the audio stops on. You can also trim the audio by clicking the speaker icon and using the Audio Tools tab that appears — look for Trim Audio to cut out the beginning or end. To hide the speaker icon during your presentation, check the box for Hide During Show in the Audio Tools menu.

PowerPoint Online (the browser version) has the same Insert > Audio path, but it only supports audio files you upload — it doesn't have the Online Audio library. Upload an MP3 or WAV file from your device, and the same playback controls appear.

Adding music in Google Slides

Open the slide where you want music. Click Insert in the menu bar, then scroll down to Audio. Google Slides will ask you to upload a file from your device or search Google Drive for one you've already saved. MP3 is the most reliable format; other formats may not play.

Google Slides doesn't have a built-in way to make audio play across multiple slides or to hide the audio player icon. The speaker icon will always be visible during your presentation, and the audio will only play on the slide where you inserted it. If you need music to continue across slides or to play silently in the background, Google Slides isn't the right choice for that task — you'd need PowerPoint or Keynote instead.

You can adjust the volume by clicking the speaker icon and using the volume slider that appears. There's no trim function in Google Slides, so if you need to cut the beginning or end of a track, trim it in a separate audio editor before uploading.

Adding music in Keynote (Mac and iPad)

In Keynote on Mac, click the slide where you want music, then go to Insert in the menu bar and select Audio. Choose a file from your device. On iPad, tap the Insert button (the plus icon), then tap Audio. Keynote accepts MP3, M4A, and WAV files.

Like PowerPoint, Keynote lets you set audio to play across multiple slides. Click the audio icon, then open the Audio inspector panel on the right side of the screen. Under Playback, you can choose Continue Playback Across Slides and set which slide the audio stops on. You can also trim the audio by clicking the audio icon and dragging the trim handles that appear at the edges of the audio timeline.

To hide the audio icon during your presentation, check Hide During Presentation in the Audio inspector. This is useful if you want background music without a visible control on the slide.

Using music libraries built into your tool

Some programs include music you can search and insert without uploading a file. PowerPoint has a small library through Insert > Online Audio. Canva, a free design tool, has thousands of royalty-free music tracks you can search by mood or genre — just click the music icon in the left sidebar, search, and insert. These built-in libraries save you the step of finding and uploading your own file.

The trade-off is selection: built-in libraries are smaller than what you'd find on a music site like Pixabay or YouTube Audio Library. If you need a specific song or a wider range of styles, you'll need to read a file and upload it yourself. Most programs accept MP3 files, which is the safest format to use.

File format and size considerations

MP3 is the most widely supported audio format across all presentation tools. WAV files work in PowerPoint and Keynote but not reliably in Google Slides. M4A (Apple's audio format) works in Keynote and sometimes in PowerPoint, but not in Google Slides. If you're unsure what format your file is in, right-click it and check the file extension — it will say .mp3, .wav, .m4a, or something similar.

File size matters for online presentations. A three-minute MP3 is usually 5 to 10 MB, which is fine. If your audio file is larger than 100 MB, some programs may refuse to upload it or may slow down your presentation file. If you're sharing your slideshow file with others, a large audio file will make the file harder to email or upload. Most audio editing software (Audacity is free) can compress an MP3 to a smaller file size without noticeably changing the sound quality.

Testing audio before you present

Audio playback can behave differently depending on where you're presenting. A file that plays perfectly on your laptop may not play on a projector, or the volume may be too low to hear in a large room. Always test your slideshow on the actual device and in the actual space where you'll present, if possible.

Open your slideshow in presentation mode (press F5 in PowerPoint, or click the play button in Google Slides and Keynote) and listen to the audio from the back of the room. Check that the volume is loud enough and that the audio starts and stops at the right moments. If you're presenting remotely, test the audio through your video conferencing software — sometimes audio doesn't pass through as expected. If something doesn't work, you have time to adjust the volume, re-trim the audio, or switch to a different file before the actual presentation.

Frequently Asked Questions

Can I make the music fade in or fade out?

PowerPoint and Keynote have fade options in their audio editing menus. In PowerPoint, right-click the audio icon and look for fade in/out controls in the Audio Tools tab. In Keynote, click the audio icon and adjust the fade settings in the Audio inspector. Google Slides doesn't have fade controls — you'd need to edit the audio file in a separate program like Audacity before uploading.

What if my audio file won't upload?

Check the file format first — convert it to MP3 if it's in a different format. Check the file size; if it's over 100 MB, compress it. If the file is corrupted, try downloading or exporting it again from the source. If you're using Google Slides, try uploading the file to Google Drive first, then inserting it from there instead of uploading directly.

Can I use copyrighted music from Spotify or YouTube?

No. Music from Spotify, YouTube, and most streaming services is protected by copyright. Using it in a presentation without permission is copyright infringement, even if you're not sharing the presentation publicly. Use royalty-free music from sites like Pixabay, YouTube Audio Library, or Epidemic Sound instead. These sites let you read music legally for presentations.

Will the audio play if I share the slideshow file with someone else?

Usually yes, but it depends on the format and the tool. If you share a PowerPoint file with embedded audio, the audio travels with it. Google Slides audio plays as long as the recipient has access to your Google Drive file. If you email a PowerPoint file, make sure the audio file is embedded, not linked — right-click the audio icon and check that it says "Embedded Audio" rather than a file path. If it's linked, the audio won't play on someone else's computer.

How do I make music play on only part of a slide?

In PowerPoint and Keynote, you can trim the audio to start and end at specific times, which effectively makes it play for only part of the slide. Use the trim controls in the Audio Tools menu (PowerPoint) or Audio inspector (Keynote). In Google Slides, there's no trim function, so you'd need to trim the file in an audio editor before uploading.
