By Cecilia Hwung | Last Update:

There come times when you have to convert MP3 to AVI for various reasons, for instance,

  • You want to play MP3 files on a dedicated video player that only handles video formats like AVI and MOV.
  • You need to add your favorite images, videos, or other visual elements to an MP3 file.
  • You'd like to post an MP3 file on YouTube or other platforms that don't accept the MP3 format at all.
  • ...

Thus, in this post, we'll look at how to (bulk) convert MP3 to AVI online or free using some of the best MP3 to AVI converters.

Convert MP3 to AVI

1. Convert MP3 to AVI Online for Free with Zamzar

If you're looking for an easy online solution to convert small MP3 to AVI, then give Zamzar a try. This online MP3 to AVI converter lets you convert up to 5 MP3 files with total sizes no larger than 50MB to AVI without paying a penny. Unfortunately, it might disappoint advanced users, since there aren't advanced options for controlling the quality, size, and other properties of the output AVI file.

Step 1. Open the MP3 to AVI conversion page of Zamzar on your browser.

Step 2. Hit Choose Files and then select the source MP3 file for adding to this online MP3 to AVI converter.

Step 3. Hit Convert Now. Zamzar starts to upload and convert your MP3 file.

Step 4. Hit DOWNLOAD on the pop-up new tab to have the exported AVI file downloaded on the computer.

2. Convert MP3 to AVI Online for Free with AnyConv

AnyConv is a straightforward online file converter that's known for being able to convert video, audio, cad, font, e-book, and dozens of types of media files. It lets you convert an MP3 file under 100MB to AVI online without logging in or installing extra plugins. Thus, it's a more generous option than Zamzar, from the aspects of upload size limits. The absence of controls for customizing the size and quality of the resulting AVI file is a sad drawback. However, that might not be a big deal for beginners.

Step 1. Open the MP3 to AVI conversion page of AnyConv on your browser.

Step 2. Hit Select File and choose the original MP3 file for loading to this online MP3 to AVI converter.

Step 3. Click on Convert to enable AnyConv to start converting MP3 to AVI.

Step 4. Hit Download to save the generated AVI file on the computer.

3. Convert AVI to MP3 Online for Free with Freeconvert

Freeconvert is one of the few online MP3 to AVI converter that can handle large AVI files as well as allows basic edits for MP3 files. Before exporting MP3 from AVI, you can adjust the length, volume, and codec for the MP3 file. You're even allowed to reverse the MP3 audio and apply a fade-in or fade-out effect. However, Freeconvert is still far from perfect. Pop-ups and ads are everywhere. The maximum upload file size for a free account is 1GB. Depending on your network condition, it might take hours to upload MBs of MP3 files.

Step 1. Open the MP3 to AVI conversion page of Freeconvert.

Step 2. Hit Choose Files and select the original MP3 file for adding to this online MP3 to AVI converter.

Step 3. If necessary, click on Advanced settings and then adjust the audio codec, volume, and other settings. Hit Apply Settings to confirm your adjustments.

Step 4. Hit Convert to start converting MP3 to AVI for free by using Freeconvert.

Step 5. Click on Download AVI to save the AVI file exported from MP3 on your computer.
