How to convert AAC to MP3 with Movavi Video Converter

Edited by Ben Jacklin

The AAC audio format was originally developed as a substitute for MP3 to provide better sound quality with the same bitrate. However, AAC files still aren't as widely supported as MP3s, which makes them less convenient for media player owners. If you want to convert .aac to .mp3, use Movavi Video Converter. It will help you change the AAC format to MP3 without perceptible quality loss. Read our short tutorial below and try the Movavi AAC-to-MP3 converter yourself.

Step 1. Install the Movavi AAC-to-MP3 converter on your computer

Download and run the Movavi Video Converter installation file. Follow the on-screen instructions to set up the app.

Step 2. Add files to the program

Add the music tracks you want to convert to the program. Click Add Media, select Add Audio, and locate the files on your hard drive. You can add several files at once for conversion in bulk.

Step 3. Select the output format

Open the Audio tab at the bottom of the window, click on the MP3 icon to expand the category, and select the bitrate that suits your needs. Here, you can choose an option to lower the bitrate, which means lowering the sound quality. However, it makes the file size lower as well.

Step 4. Switch the format to convert AAC to MP3

Click the Save to button and select the folder in which the converted files will be saved, then click Convert to change your AAC file to MP3. When the process is over, the specified folder will open automatically.

Great! Now you know how to change AAC files to MP3 with Movavi Video Converter.
