What is AVI to MP4 Converter?

AVI to MP4 Converter is software, app, or online tool that formats your file to MP4.

AVI is an acronym for Audio Video Interleaved file. It is an audio and video file format developed by Microsoft.

AVI files store high-quality video with low compression compared to MP4, MOV, and MPEG formats.

Why would you want to convert AVI to MP4 if it has all these top qualities?

The answer is in its size. AVI files are large, about 3 GB per minute of video. Users with limited storage cannot keep many of these files.

Also, retrieval and playback require experimenting with codecs which are highly inconvenient.
