PNG sequence → animated WebP transparent

Drop a PNG sequence ZIP (the same one Spinly's PNG sequence export produces) or pick individual transparent PNGs. You'll get an animated WebP with full alpha-channel transparency — much sharper edges than GIF, and a fraction of the file size.

Tip: WebP animation is supported in all modern browsers, native iOS/Android, Slack, Discord, GitHub README, Notion, and most CMSs. For very old systems, GIF is still a fallback (Spinly exports those too).
