How to convert large AVI to MP3 with Movavi Video Converter
Step 1. Install Movavi Video Converter
Download the AVI-to-MP3 converter for PC or Mac, depending on your computer’s OS. Then, launch the installation file and follow the on-screen instructions.
Step 2. Add your media
Run the program. Click the Add Media button in the main window. To convert .avi to .mp3, choose Add Video. With the desktop version, you can select several files simultaneously, which isn’t supported by the AVI-to-MP3 converter online.
Step 3. Adjust the file length
Here’s another trick unavailable if you convert AVI to MP3 online. If you don’t want the whole video or audio to be converted, you can cut out the parts you don’t want. Here’s how to do it: locate the Edit button next to the file you want to trim (on the right) and click it.
A new window with the video preview will appear. Place the marker at the spot you want to cut the video and hit the Scissors icon. This will split the video into parts. Hit the Delete button to remove the unwanted segment. Repeat as needed and then click Save and Close to return to the main window.
Step 4. Choose the output format
Now your files are ready to be processed. Go to the Audio tab and choose the MP3 group of presets. Select the option you prefer: the original bitrate or another between 128 and 320 kbps. The output format will be shown below the preset groups.
Step 5. Start the conversion of AVI to MP3
The last part is the simplest one. Choose the target folder for the converted files by clicking the Save to button. Hit Convert and wait for a short while until your files are ready. Now you can enjoy your favorite audio tracks anywhere!
