常見問題
- Will Safari play WebM?
- Safari 16+ on macOS and iOS plays VP9 WebM. For older Safari support, use MP4 instead — see <a href="/anim/gif-to-mp4/">GIF to MP4</a>.
- Why does encoding take a while?
- VP9 is computationally heavier than H.264. Worth it for size: WebM is often 30–50% smaller than MP4 at the same quality.
