Convert MPG to AVI — Free Online Converter

MPG and AVI are both legacy video formats from the 1990s, but they use different container structures and codec ecosystems. MPG wraps MPEG-1/MPEG-2 video with MP2 audio in an MPEG program stream, while AVI (Audio Video Interleave) uses Microsoft's RIFF container to interleave audio and video chunks. Converting MPG to AVI repackages the content for the Windows ecosystem, making it compatible with Windows-centric media players, video editors, and hardware devices that prefer the AVI container.

Many legacy Windows applications, video editors (Windows Movie Maker, early VirtualDub), and hardware devices (DVD players with USB, older car entertainment systems) specifically require AVI format. If you have MPG recordings from TV capture cards, surveillance systems, or DVD rips that need to work in these Windows-specific environments, converting to AVI ensures compatibility.
