Using WebM with transparency

Transparent WebM replaces heavy PNG sequences, Lottie-incompatible effects and GIFs with poor edges. It keeps full 8-bit alpha, so shadows and glows stay soft.

Autoplay it muted and looped in a video tag, and consider an HEVC-alpha MP4 as the first source for Safari users.

Frequently asked questions

Does WebM transparency support soft edges?

Yes — unlike GIF, WebM keeps a full alpha channel, so feathered edges and shadows look right.

Will this work for animated logos?

Yes, that is one of the most common uses.

How big are transparent WebMs?

Usually a small fraction of the ProRes source — often a few hundred kilobytes for a short logo animation.
