About This Conversion
MP4 (MPEG-4 Part 14) is today's dominant video format, offering excellent compression and universal device support. AVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992 as part of its Video for Windows technology. While AVI is an older format, it remains widely used in certain workflows and is supported by virtually every media player ever made. An MP4 to AVI converter is useful when you need to work with software or hardware that specifically requires AVI input, such as certain older video editing programs, industrial equipment with embedded displays, or legacy media servers. AVI files can contain video compressed with various codecs including DivX, Xvid, and uncompressed video. Our free online MP4 to AVI converter runs entirely in your browser, processing your videos privately without any server uploads.
