VP9 vs H.264 - which codec for web delivery?
VP9 gives ~30% smaller files than H.264 at comparable quality. Native browser playback in Chrome/Firefox/Edge. Creator-platform acceptance is uneven (TikTok VP9 in limited paths; YouTube supports VP9). Choose H.264 unless web-native delivery is the priority.
What differs
| Criterion | H.264 (AVC) | VP9 | Verdict | Origin |
|---|---|---|---|---|
| Browser playback | Universal. | Chrome / Firefox / Edge; Safari limited. | prefer-a | sourced / sourced |
| File size at equivalent quality | Baseline. | ~30% smaller. | prefer-b | guidance / measured |
| Creator platform support | Universal. | YouTube (full), TikTok (VP9 in some paths). | prefer-a | sourced / sourced |
Decision table
| Goal | Recommendation | Reasoning |
|---|---|---|
| Web-native delivery (Chrome / Firefox) | prefer-b | VP9 wins on file size + native playback. |
| Multi-platform creator publishing | prefer-a | H.264 is universal. |
Recommendation
Choose VP9 for web-native delivery. Choose H.264 for multi-platform creator publishing.
