AVI to MP4 modernizes legacy video files. AVI often causes compatibility problems on mobile devices and web platforms, while MP4 is widely supported and easy to share.
Use this conversion to make older videos play smoothly on modern devices. For web-first optimization, convert to MP4 first, then consider MP4 to WebM.
