Video File Formats Explained: MP4 vs WEBP vs AVI

Video content is everywhere, but not all video formats are created equal. Different formats offer different trade-offs between compatibility, quality, and file size.

MP4 (MPEG-4 Part 14)

The industry standard for web video. Universal browser support, excellent compression, supports HD and 4K. Best for web streaming, mobile video, and social media.

WEBP

Google's open-source video format. Royalty-free, excellent compression, modern features, and growing browser support. Best for open-source projects, web applications, and future-proofing.

MOV (Apple QuickTime)

Apple's video container format. Native macOS support, high quality, professional editing tools. Best for Mac applications, video editing, and Apple ecosystem.

AVI (Audio Video Interleave)

Legacy Windows video format. Wide codec support, simple structure, and legacy compatibility. Best for legacy systems, simple video players, and specific use cases.

MKV (Matroska)

Universal video container format. Supports multiple tracks, unlimited codec support, subtitle support, and chapter support. Best for media centers, video collections, and complex video files.

Choosing the Right Format

Consider target platform, browser support, quality vs size priorities, and feature requirements like subtitles and chapters.

Recommendation

For most web applications, use MP4 with H.264 codec for maximum compatibility. For cutting-edge projects, consider WEBM or AV1 for future-proofing.
