AVI (Audio Video Interleave) is an older video format developed by Microsoft. While still playable on most devices, AVI lacks modern compression efficiency, leading to larger file sizes than MP4 or MKV. It does not support newer codecs like H.265, making it less ideal for high-definition content. However, its simplicity ensures basic compatibility with legacy systems.
A WebM file is a modern, royalty-free multimedia format optimized for web use. Developed by Google, it uses efficient VP8 or VP9 video compression alongside Vorbis or Opus audio codecs. WebM is perfect for HTML5 video streaming, offering excellent quality with smaller file sizes compared to MP4. It's widely supported in browsers like Chrome, Firefox, and Edge, making it a top choice for web developers and content creators.
