Big-Animation Accelerator

Make large animated WebP / GIF files load instantly in Safari

Problem
Safari handles large animated WebP files poorly: they load slowly and seem to be decoded constantly, tanking performance. One developer had to build a Safari extension just to work around it. Regular users just feel "laggy" without knowing why, and there's no one-click fix.
Solution
A browser extension (Safari first, then Chrome): detects oversized animations, automatically reduces frame rate, decodes on demand, or transcodes to lighter formats, and shows per-page CPU/memory usage so users can see the problem.
Users
Designers, marketers, and heavy browser users who browse GIFs, memes, and asset sites
MVP
Safari extension; detect animated WebP/GIF above a threshold; auto-reduce frame rate or pause off-screen animations; show resource usage per page; one-click whitelist toggle
Revenue
Free basic tier, one-time Pro purchase for advanced transcoding and stats; or affiliate deals with performance monitoring tools.
Why now
Animated WebP and high-FPS content are everywhere in social and AI-generated media, and Safari's weakness remains unfixed—a small tool can show immediate value.
