If you’ve created music, a podcast, or a voice over in GarageBand, the next step is sharing it. But by default, GarageBand saves your project in a proprietary format that isn’t ideal for sharing or playback on most devices. That’s where exporting to MP3 comes in.
Whether you’re using GarageBand on a Mac or via a virtual machine on a Windows PC, this guide will walk you through the simplest way to export your GarageBand project as an MP3 file in 2025, using the most up-to-date method available.
Why Export GarageBand Files to MP3?
GarageBand saves your recordings as .band project files that contain multiple audio and instrument tracks. These are useful for editing, but not for sharing.
MP3 files, on the other hand, are:
- Compressed and lightweight (ideal for email, social media, or streaming)
- Universally compatible (playable on phones, tablets, computers, and media players)
- Faster to upload and easier to manage
Step-by-Step Guide: Export GarageBand to MP3 (macOS Sonoma / Ventura)
Step 1: Finalize and Save Your Project
Make sure your audio is complete and sounds the way you want. Save your project:
- Go to File > Save.
- Name your project and confirm it’s saved to a location you can access later.
Step 2: Set Your Export Parameters
- At the top menu, click Share > Export Song to Disk.
- A dialog box will appear asking for:
- File Name – Set your title.
- Location – Choose where you want the file saved.
- File Format – Select MP3 from the list (other options include AIFF, WAV, and AAC).
- Audio Quality – Choose from Good, High, or Highest. For web sharing, “High” is a great balance of quality and size.

Troubleshooting Export Issues:
Even with the latest version of GarageBand, users sometimes run into snags. Here’s how to handle common problems:
1. Export button is greyed out?
- Make sure a track is recorded and not muted.
- Disable Cycle Mode (yellow bar at the top timeline) unless you only want to export a specific loop.
2. File exports but no sound?
- Ensure your project volume is up and tracks are unmuted.
- Check if plugins or effects are causing playback errors.
3. File is too large or low quality?
- Select MP3 > High or Highest Quality in the export options.
- Avoid exporting in WAV or AIFF if file size is a concern.
