VP8 provides wider compatibility with older browsers. VP9 is especially beneficial for HD and 4K content where bandwidth savings are significant.

WebM with VP9 typically produces files 30-50% smaller than MP4 with H.264 at the same quality. For 1080p video, expect 40% reduction; for 4K content, savings can reach 50%. The efficiency improves with higher resolutions, making WebM ideal for HD streaming while reducing bandwidth costs.

WebM is excellent for web backgrounds! Smaller file sizes mean faster page loads, VP9's efficiency allows high-quality backgrounds with minimal bandwidth, and native browser support ensures smooth playback. Use muted WebM videos for auto-play compatibility and consider providing MP4 fallback for Safari users.

Opus is the recommended audio codec for WebM - it provides superior quality at lower bitrates than AAC or MP3. Use 128 kbps Opus for excellent quality, or 64-96 kbps for good quality with smaller files. Vorbis is the legacy option with wider compatibility but larger file sizes.
