Video Formats Explained: MP4, WebM, AVI, and When to Use Each

Video format confusion is common with dozens of options. Understanding the main formats helps you choose correctly for sharing, editing, and streaming.

MP4

The universal standard with H.264 encoding. Excellent compression quality balance. Virtually every device plays MP4 natively. The safe default for most purposes.

WebM

Uses VP9 or AV1 codecs with better compression than H.264. Open-source and royalty-free. Chrome and Firefox support natively. Use alongside MP4 for web delivery.

Choosing

MP4 for distribution and social media. Add WebM for web optimization. Keep source files in native format for editing. Online converters handle format changes without software installation.
