Convert MPG to AVI Online
Compression efficiency is far behind modern codecs; an MPEG-2 file is typically 3–5x larger than equivalent H.264. Converting to AVI gives you a key advantage: extremely simple container structure that every windows media tool has supported since 1992. AVI is best for storing uncompressed or lightly compressed video for editing on windows-based workflows.

What's the difference between MPG and AVI?
expand_more
MPG (MPEG-1/2 Video) is best for playing legacy vcd and early dvd video content from the mpeg-1 and mpeg-2 era. AVI (Audio Video Interleave) is best for storing uncompressed or lightly compressed video for editing on windows-based workflows. Key tradeoff: MPG's advantage is universal hardware decoding support — every dvd player, tv, and media device produced since the late 1990s can decode mpeg-2, while AVI's advantage is extremely simple container structure that every windows media tool has supported since 1992.
