AVI (Audio Video Interleave) is Microsoft's classic multimedia container format. Although MP4 has become the universal standard for web and smartphones, millions of standalone DVD players, in-dash car stereos, TV USB ports, retro gaming consoles, and legacy video editing suites only support standard AVI video files. Our MP4 to AVI Converter bridges the gap between modern MP4 video clips and legacy hardware devices directly in your web browser with 100% privacy.
