AVI (Audio Video Interleave) uses uncompressed or lossy encoding and is best for legacy video compatibility — older software, embedded systems, and archival playback. MP4 (MPEG-4 Part 14) uses lossy compressed encoding and excels at universal video playback on any device — phones, smart TVs, web browsers, and social media. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
