AVI videos may not always play properly on your devices. Because of its ubiquity and wide compatibility, converting AVI to other video formats, such as MP4, is a good idea. MP4 is a well-known video format that provides high quality and compatibility with any device. This article will show you the best and easy ways to convert AVI to MP4 on Windows 11/10, Mac and online. These processes are incredible and quick to follow. Without further discussion, here is the best process for converting AVI to MP4 and MP4 to AVI using the desktop program and an online tool.

Convert AVI and MP4

Part 1. MP4 vs. AVI

As we begin the guideline on converting MP4 to AVI or vice versa, we shall start this post by defining the similarities and differences of each file format. In line with that, let us now differentiate MP4 and AVI in three main points that are written below: Quality, Compatibility, and Storage Efficiency. Three important things that we need to understand.


When comparing the quality of AVI and MP4, keep in mind that both formats are video wrappers. AVI is related to the DivX codec, whereas MP4 is associated with the MPEG-4 AVC/H.264 codec. Another distinction is that AVI can store an alpha channel, producing a higher-quality output file than MP4. Unlike AVI, MP4 may use many compression codecs, resulting in improved performance efficiency with comparable quality. Ultimately, there is no discernible difference between AVI and MP4 video. AVI, on the other hand, delivers slightly superior video quality than MP4.


Another significant advantage of MP4 over AVI is that it is compatible with most devices, but AVI may require specialized players to run. Conversely, MP4 is a better format than AVI for almost all applications. If simply visual quality matters, you might pick AVI over MP4.

Storage Efficiency

AVI video formats compress data less efficiently than MP4, MPEG, and MOV video codecs. As a result, the typical file size is 2-3 GB for every minute of video. This is an issue for those that have limited storage space. AVI files, on the other hand, can be compressed by converting them to other formats such as MOV, FLV, or MP4. MP4 is a lossy format that compresses well and takes up significantly less storage space than AVI.
