About This Tool

AVI (Audio Video Interleave) is a classic multimedia container format developed by Microsoft. While MP4 is the modern standard, AVI remains widely used in legacy systems, older media players, and certain professional video editing workflows. Some older DVD players, embedded systems, and Windows-based applications specifically require AVI files. Converting MP4 to AVI ensures your videos are compatible with these older platforms and devices. All processing happens directly in your browser using WebAssembly technology for complete privacy.
