Step 1. Import Your AVI Files

Step 2. Set Output Format to MP4

Click the format image on the right to check the full list of 500+ pre-made output profiles. Then head to Video > MP4.

The built-in Smart Fit feature will automatically match the optimal parameters based on your format selection. Also, you can choose to tailor the output settings by yourself: open Parameter settings to change the codec, resolution, frame rate, aspect ratio, and more.

Step 3. Start Converting AVI to MP4

Click the inverted triangle icon in the output folder box to set a file destination. Finally, click the Run button to start the process of converting avi files to mp4.

  1. VLC Media Player

No surprise. VLC, besides being a player, also has the ability to make format conversions. I believe many users have learned about this feature. If you’ve already had this functional player installed on your device, then follow our instructions to see how to convert AVI to MP4 for free using it. BTW, VLC can work with various OS, including Windows, Mac, and Linux.

Step 1. Download and install the latest version of VLC from its official website.

Step 2. Open VLC. On the top menu bar, click “Media” > “Convert / Save…” (or press “Ctrl + R”) to open the “Open Media” window.

Step 3. Click “+ Add…” to select the AVI videos you want to convert. Then click the “Convert / Save” button at the bottom.

Step 4. Then hit the “Profile” drop-down list and select “Video – H.264 + MP3 (MP4). Also, you can choose an MP4 paired with other codecs like HEVC/H.264, or hit Create a new profile to customize the output settings to your needs. But this requires some encoding knowledge.

Step 5. When you’re comfortable with the settings, click on the Browse button to set an output folder and rename the file with a .mp4 extension.

Step 6. Finally, click Start to begin converting AVI to MP4.

  1. HandBrake

HandBrake is a popular open-source video transcoder. It offers a free and convenient way for both Mac and Windows users to change the AVI format to MP4. With an array of customizable settings provided by HandBrake, you can process your videos to MP4 with the desired quality. However, this program now only offers three output video types: MP4, MKV, and WebM.

Step 1. To avoid unnecessary issues, make sure you’re using the latest version. Get it at the official website.

Step 2. Open HandBrake and click Open Source to add your AVI file.

Step 3. Select a preset from the Preset drop-down menu.

Step 4. Click on the Summary tab and choose MP4 as the output format.

Step 5. Switch to other tabs to modify the encoding settings if needed.

Step 6. Click Browse to rename the export file and set an output folder.

Step 7. Finally, click on Start Encode to start the conversion process at once.

Part 2. How to Convert AVI to MP4 Online?

Personally, desktop tools are always my first choice because they are usually safe and stable. What's more, the conversion speed and quality of a reliable desktop AVI to MP4 converter are better than most online services. But if you only need a converter for one-time use, using a free online AVI to MP4 converter might be a better choice.

  1. Online Video Converter

Online Video Converter provides a straightforward video conversion process. It supports all mainstream video formats, and without the need to register or install any plug-ins, you can use it to convert AVI to MP4, AVI, MPEG, MOV, MKV, and more formats. It allows you to upload video files up to 4GB: Simply upload your AVI video, click "Convert", and download the converted file.

  1. Convertio

Convertio is one of the most popular online video converter programs that can turn AVI into MP4 in a simple and fast way. It allows you to add several files together and convert them to the desired format simultaneously. There are also options for you to adjust the video by cutting, rotating, resizing, etc. However, you cannot convert large files with it since the free plan of Convertio only supports maximum file size under 100 MB.

In Conclusion

With the AVI to MP4 converters and steps above, you can now perform the AVI to MP4 conversion on Windows and online effortlessly. Among those AVI to MP4 converters, we highly recommend WonderFox HD Video Converter Factory Pro. It not only can help you change your video and audio formats but also enables you to do more with your video files, bringing you an all-in-one solution to ease your multimedia life!
