2. What Are the Differences between AVI and MP4

AVI is a multimedia container format released by Microsoft in 1992. It can store both video and audio content. The biggest advantage of AVI is the video quality partly because it is a lossless video format. However, AVI video files are very large and not friendly on mobile devices or the internet.

MP4, one the other hand, is a lossy video format compressed by MPEG-4 Part 14. Compared to AVI, MP4 can produce smaller file size but not damage the quality very much. Plus, MP4 is the most commonly used video format, so it works fine on all digital devices. That may be why you want to convert AVI to MP4.

Conclusion

This guide showed you how to convert AVI to MP4 without damaging the video quality. Firstly, HandBrake and VLC Media Play are able to transform your video files from AVI to MP4 format for free. However, they have unavoidable downsides, such as unintuitive workflow or messy interface. Therefore, we recommended FoneLab Video Converter Ultimate, a more flexible AVI to MP4 converter. It is not only easy to use, but also able to produce the best output quality.
